Prospects for modular weapons

The reason for writing this material was the recently published VO article “Why modular weapon there is evil. "

To form a more complete picture, I decided to supplement the topic with arguments in favor of modular weapons.



The place of modular weapons in modern aircraft


Modern warfare is becoming more and more technological - this inevitably affects the requirements for the level of training of both the rank and file and the command.

The low effectiveness of the "urgent draft" has long been evident. What can you teach a person in two years, and even more so in one?

The next logical step was the creation of the MTR (Special Operations Forces) - professionally trained high-level military personnel.

The high level of training allows you to use a much larger arsenal of tactics.
The set of tactics available directly depends both on the equipment of the fighters and on their training. A unit cannot effectively use mines if the fighters are not trained to do so. The commander cannot plan an attack at night, taking advantage of the fact that his fighters have a NVD if they do not have a NVD.

One is interconnected with the other - knowledge, skills, equipment.

Therefore, equipment flexibility is a very important issue for the MTR.

Why do you need different weapons?


Let me give you a simple example. For a long time, the United States fought in Iraq. And most of the operations with fire contacts took place in urban (by Iraqi standards) buildings.

At the same time, in Afghanistan, the militants at some point realized that, using 7,62 calibers against the United States, they were able to more confidently hit their targets. While the forces of the "coalition" were forced to shoot with a smaller caliber.

In mountainous conditions (where there are significant changes in altitude and temperature), the direction and strength of the wind changes in large ranges, so a heavier ammunition will always be more preferable.

In view of this, it is impossible to create one machine gun for the entire army, which at the same time will show high efficiency in all situations. And therefore, we will not be able to get away from creating weapons in different calibers and with different barrels.

The only question is whether it will be a modular option or not.

Tactical demonstration


To demonstrate how it all looks in practice, imagine that you are in command of a platoon, which consists of three squads of eight each.


You are based at Outpost Charlie and there is a small village 20 km away. In addition to you, there are still personnel at the base, but one of your departments must participate in the protection of the base.

To increase your firepower, you arm the squad participating in the protection with 4 machine guns.

Then an order comes - to patrol the road on a section of 10 km. This task is assigned to the 2nd department. The third - remains on the base in a state of BG (combat readiness).

There is also a report that a week ago a patrol was ambushed in a neighboring area, and fire was fired, including from several SVDs.

You decide to arm the patrol squad with a large number of long-range rifles - instead of 1 infantry sniper becomes 3.

Two days later, you are ordered to search houses in a nearby village. Two squads provide cover while staying outside. And the village itself is entered by a unit equipped with weapons with short barrels, more convenient for indoor combat. Including with 2 light light machine guns.

Obviously, to provide the same level of tactical flexibility, a whole arsenal of weapons was needed.

An important factor is the fact that all these weapons must be regularly serviced and monitored for combat readiness.

Next, let's look at the most erroneous cons.

In battle, there is no time to change barrels and it is difficult


Any weapon needs maintenance, cleaning and lubrication. Regardless of whether it is modular or not.

It is necessary regularly partially disassemble and reassemble, which is much longer than changing the barrel.

Much longer.

For an example video:


Of course, in the army, as elsewhere, there are different people and different commanders.

It is my deep conviction that in a professional army, commanders are obliged to monitor how their subordinates maintain their weapons. And also maintain skills, which means shooting and cleaning weapons.

Thus, changing the barrel is not a shuttle launch, but a primitive and typical operation.

Mastering a military profession implies the presence of much more complex skills. And if it is difficult for a person, it will be better for everyone if such a person does not get into the army.

I can also recommend for watching a video about the training camp of the 56th Air Assault Regiment in Chechnya (the legendary 56th Air Assault Regiment goes to work). I cannot include a link to this video in this article, because the commander uses specific vocabulary there, and also explains his position regarding two fighters who did not allocate time to service their weapons.
It also says about the app. trunk.

Modular weapons are expensive


The cost argument can be criticized from two completely different points of view.

1) To train MTR fighters is much more expensive than the cost of one sample of small arms. Arming trained people with cheap weapons is not the most effective tactic.

2) More expensive in relation to what? If we have a “carcass” and 3 types of barrels for it, it will be cheaper than 3 full-fledged rifles with a fixed barrel.

You will have to carry a lot of spare parts with you


On the contrary - 1 repair kit fits the entire armament of the compartment.

What can not be said about the situation when the department has PKK, Pecheneg, SVD, AKSU and Ak-104.

In addition, one long barrel for the entire compartment (worn as a spare) is not only an opportunity to change the configuration of one of the available samples, but also a "repair" one for all.

What do our designers say?


In conclusion to the analysis of foreign experience carried out by specialists of the Kalashnikov concern, it is said:

"The lack of domestic innovative weapons developments of strategic importance, for example, new generation machine guns for the needs of certain units of the Armed Forces of the Russian Federation, emphasizes the presence of problems with the formation of a modern weapons scientific base, adequate to the goals of competitive development of the shooting industry."

That is, in addition to tactical aspects and issues of application, two problems of a production-market nature are formulated at once:

1. A different level of manufacturability of production. It is absolutely essential that our industry and the arms industry be able to produce weapons at a modern level.

2. Export potential. Here, I think, everything is also clear.

General tendencies towards weapon complexity



Looking at the kit above, you might get the impression that this is all getting "too complicated".

The soldier begins to resemble a musician who comes to a concert with his instrument.

Of course, this is of little use everywhere. However, if we take into account the MTR, their equipment already contains a large number of high-tech elements (optics of different magnification, collimators, night vision devices, pbs). One good sighting system can cost as much as a machine gun itself.

Optical reconnaissance systems, duplicated communication systems, army tablets that allow integrating a combat group into a single battlefield.

In the near future, small reconnaissance quadrocopters will be put into service. At the branch level there will be an operator of such drone.

As a result, interchangeable barrels are the least of the problems in the maintenance of the rest of the high-tech equipment.

Conclusions


Modular weapons are an unconditional trend in the modern industry. Dictated not by simple fashion, but by the real advantages in tactical flexibility that modular weapons can provide to special operations forces.

Also, technologically advanced production can be useful for the manufacture of conventional weapons.

It is very good that the Kalashnikov concern understands this. And our army is aware of this as well - the new AK-12 weapons are already entering the troops. And even more - it managed light up in Karabakh.

So far, modularity is limited to 2 barrels.

In the future, we are "waiting" for the RPK-16 to enter service.

      I think, according to our tradition, the decision to replace the barrel at the level of the commander of the MSO will not be omitted. There is the main organizer of actions - the commander of the regiment (brigade, separate MRB), so he will determine, together with his headquarters, who to cut what tasks and what weapons to use at the same time, based on the availability of ammunition, specialists and other related conditions.

      Maybe it will be news to you, but the commander should puzzle over something like that.
      He must assess places in terms of danger, possible threats. Should try to predict the scenarios, how he would attack on the spot of the enemy.
      He must control and make changes to the distance and formation.

      And barrels are an additional tool in his arsenal.

      I can only advise you to familiarize yourself with the VSO concept.
      The concept of the US army developed on the basis of an analysis of the experience of the USSR and the US itself in Afghanistan.
      Much is explained there, including the relatively brilliant ideas for couch warriors to drive armored vehicles onto goat paths and replace people on earth with drones.
      VSO is one of 30 subsections of a more global concept, and it doesn't hurt to study it too.

    "Notes in the margin"
    The low effectiveness of the "urgent draft" has long been evident. What can you teach a person in two years, and even more so in one?

    Of course, even service in the prince's squads (the tsarist army) showed the effectiveness of professional military personnel. An urgent call could be used when the tactics of the battle and the weapons themselves were not difficult. BUT!!! Let us and we draw a distinction between the Armed Forces and the MTR.
    Let me give you a simple example. For a long time, the United States fought in Iraq. And most of the operations with fire contacts took place in urban (by Iraqi standards) buildings.

    In the war "FOR FREEDOM AND INDEPENDENCE" such territory is "cleared" with the help of missile and bomb strikes (with all the entrapment that was there), thereby ensuring the advancement of troops and the execution of tasks without loss of l / s. And in the event of US aggression, such "fire contacts" and other clashes with the local population were inevitable.
    Then an order comes - to patrol the road on a section of 10 km.

    Two days later, you are ordered to search houses in a nearby village.

    Is it the army or the military police? What are the general goals of future wars and how do they differ from the goals of "providing military assistance in order to preserve the sovereignty of the state or the power of a certain circle of people"?
    Modular weapons are an unconditional trend in the modern industry. Dictated not by simple fashion, but by the real advantages in tactical flexibility that modular weapons can provide to special operations forces.

    This is the main point of the article. We realized this long ago. Sophisticated weapons require honed skills that long training provides. It is also clear that small arms (weapons for one person or a small group) should facilitate the performance of various tasks with minimal losses. Only the specificity of hostilities in this case differs from the specificity of inflicting preventive attacks with the use of nuclear weapons.
    The most important thing in this "modularity" is not to go too far. In order not to deal with the components of this "supermodule" in a difficult situation.

    It is very important that all samples of small arms have various observation and aiming devices in different conditions. A thermal imager, night vision device, a collimator sight and a tactical sight with several times magnification are what should be for each weapon and then, trained personnel, with proper planning of the operation, with the organization of communication and interaction, will complete the task.

    For a specialist or drg, modularity is a blessing. For a line infantryman who stands at a checkpoint, patrols on highway armor or simply guards a base as part of a guard, it is not needed.
    Or rather so. Replaceable modules and repair kits can also be available, but the weapon configuration will most likely be done once and for a very long time. And the "extra" iron is stored in the weapon. On account of the fact that to carry with you any of the modules, it seems complete nonsense, with the exception of the barrel for a light machine gun, which carries the main fire load in the unit. To retrain a submachine gunner into a sniper, as well as vice versa, as if no one will. A normal (not city special forces) sniper rifle will always be sharpened for a powerful rifle cartridge, as well as an assault / machine gun for an intermediate one. In the end, modular small arms are unlikely to ever become dominant in the military. And it will almost certainly become the usual equipment of special units.
    Somehow it seems to me ...

        Here at the base, at the stage of preparation for the exit, modularity may be in demand. Directly on a combat mission, this is already nonsense. And all this concerns the MTR. But it makes no sense to save space and weight on the base. Therefore, you can simply select the required weapons from the available modular designs without any there.

    Author, this is when the AK-12 became modular? The barrel cannot be unscrewed there by hand in the field with a minimum tool.

    Otherwise, I agree. For the MTR - a necessary thing, for the rest - hardly.
    For example, the Barrett Mk22 sniper rifle, which has just entered the US MTR. Three interchangeable barrels with calibers - 308 Win, 300NM, 338NM.

    And let's remember the history of the Great Patriotic War ... In October 41, there was a requirement to create a company of machine gunners at the rifle regiments. But the release of the PPSh was insufficient to fully fulfill this requirement, for example, in the battles near Rzhev in winter and spring, the 4 companies of the 46th separate motorcycle regiment, the reserve of the commander of the 30th army Leliushenko, whose combat strength was fully armed with automatic weapons, was used by the port to strengthen the small arms regiments during the assault on the support nodes, and there was a certain battle tactics - before the attack, in the dark, the submachine gunners moved to a distance that allowed the use of PPSh. And at that moment when the Germans opened fire on our attacking lines, submachine gunners entered the battle from a short distance, extinguishing the firing points of the Germans. is not this the use of modular weapons. Further, already in the 43rd, a sniper platoon was added to individual companies of machine gunners of rifle regiments, the tactics of using these companies significantly expanded. For example, 1199 joint venture 354 rifle division used a company of machine gunners in a little-known battle using an underground tunnel under German trenches, but that's a different story.
    Therefore, I think any unit should have a set of weapons that allows them to perform a combat mission with the appropriate specialization of personnel, a sniper, a grenade launcher, a machine gunner. And to redefine the combat purpose by changing the barrels is expensive and not advisable.

    The low effectiveness of the "urgent draft" has long been evident. What can you teach a person in two years, and even more so in one?
    An extremely controversial statement. There are quite enough examples to refute it. Both from a historical perspective and modern ones.
    In addition, the low efficiency of urgent conscription consists of the following parts: a drop in the level of education in the country (a fundamental issue), a drop in moral volitional qualities in society and among conscripts as part of this society (a fundamental issue)
    In view of this, it is impossible to create one machine gun for the entire army, which at the same time will show high efficiency in all situations. And therefore, we will not be able to get away from creating weapons in different calibers and with different barrels.
    Yah! Or maybe you just need to train personnel for shooting training, not saving on shooting in various conditions? And timely replace worn out weapons.
    experts of the Kalashnikov concern, it is said:
    "The lack of domestic innovative weapons developments of strategic importance, for example, new generation machine guns for the needs of certain units of the Armed Forces of the Russian Federation, emphasizes the presence of problems with the formation of a modern weapons scientific base, adequate to the goals of competitive development of the shooting industry."
    The concern's specialists are somewhat disingenuous. There are examples of shooters. And even quite a good shooter. But there is no mass production. Small batch only. Because efficiently defective management is unable to think about the establishment and functioning of production. Neither morally - to give up part of the super profits in favor of the development of production, nor physically - the level of professional suitability in the field of production management has dramatically subsided. And this is a question for the state education system ... sorry, enlightenment. In our country, everything is already so bad as in the Middle Ages that it did not come down to education, accessible to everyone, but to the enlightenment of the diligently oskotinized people. If capitalism had such an opportunity, ordinary literacy would have already passed into the category of elite skills.
    Therefore, everything is sad with production. We can create excellent samples, we can create a small series, large-scale production is a problem.
    Thus, changing the barrel is not a shuttle launch, but a primitive and typical operation.
    A non-firing high-precision tuned target weapon up to the level of a standard army model. From which the author diligently convinces to refuse. And if for a machine gun in conditions of high-intensity combat this is not a problem, then for a sniper weapon it is quite enough.
    If we have a “carcass” and 3 types of barrels for it, it will be cheaper than 3 full-fledged rifles with a fixed barrel.
    That's a very, very not a fact. Three full-fledged Mosin rifles (if we talk about rifles) or three full-fledged sighted Kalash or three of the same sighted AR-15 cover a multi-caliber device at a price (or rather cheapness) like a bull a sheep.
    At the same time, in battle "three full-fledged rifles with a fixed barrel" firing simultaneously - these are three combat units. And one multi-caliber - one combat unit with a bunch of multi-caliber junk to boot. Which cannot be thrown out and interferes in such a way that it is mortally dangerous both for the fighter himself and his comrades. We still do not remember the need for ammunition for all this wonderful miracle. For all calibers.
    Looking at the kit above, you might get the impression that this is getting "too complicated". The soldier begins to resemble a musician who comes to a concert with his instrument.
    Of course, this is of little use everywhere. However, if we take into account the MTR
    What does the MTR have to do with it? The author tried to talk about the army as a whole. There was even a passage about the obsolescence of the conscript army.
    As a result, interchangeable barrels are the least of the problems in the maintenance of the rest of the high-tech equipment.
    This is the least of the problems a fighter (and according to the author's plan, ALL fighters or most of them in a unit) should carry in a backpack. Along with "high-tech equipment", food, clothing, water, first aid kit and other things. And again, remember the ammunition. Such is the low, vile prose of life - ammunition. Not to mention the increased ammunition. For each of the calibers of the proposed multitool. Let the author try and share his impressions. Just let him try not in an hour-long march at the stadium, but in a week-winter. Yes, through the hills, ravines, forests.
    You are based at Outpost Charlie and there is a small village 20 km away.
    Is the author exactly talking about the Russian army? ..
    There is also a report that a week ago a patrol was ambushed in a neighboring area, and fire was fired, including from several SVDs.
    You decide to arm the patrol squad with a large number of long-range rifles - instead of 1 infantry sniper becomes 3.
    First of all, we, as the commander of the MTR unit, believe that patrolling the villages and the roads between them is the task of motorized riflemen (conscription army), not MTR. Well, okay, an order is an order - to hammer in nails with a microscope. We decide to reinforce the patrol with an APC or two. With an anti-sniper caliber of 30 mm or so in the turrets. We also launch a couple of drones with thermal imagers into the vanguard. After all, the author himself says in the article that we have heaps of this stuff in the MTR, right down to the starships. And only with a modular shooter a little bobble, incomplete.

    Eventually. The author began for a massive professional army and that the conscript army is byaka. That modular shooting is required for the entire army as a whole. I ended up examining the highly specialized tasks of the MTR units.

        In the section "Why do I need different weapons?" the author talks about the caliber and weight of the bullet. Says heavier ammunition is preferable. This is more an indication of multi-caliber than barrel length. I proceeded from this.

For the next business trip, you can again redo. Something like this?

    Again delirium pours in full flow. In the army, everything should be extremely simple, reliable, cheap and effective. A modular weapon with a bunch of replaceable junk does not meet any of the above criteria. I'd rather have a good old, reliable AK-74 and more cartridges for it than a modular one with a bunch of replaceable junk and cartridges of different calibers. I have no idea how an ordinary motorized rifleman would carry with him an assault rifle with 2-3 barrels of different caliber, 2-3 sets of different cartridges, different magazines for them. And so in the armored personnel carrier and BMP there is no place inside, and here the author proposes to fill it all with junk.

      I have no idea what the hell is going on in your heads and those like you, and where did you get the idea that a motorized rifleman should will carry with him a machine gun with 2-3 barrels of different caliber, 2-3 sets of different cartridges, different magazines for them. You have something in your head thoroughly crap.
      Nobody forces anyone to do this. Modularity is opportunity, not a duty.
      In addition, at the moment, this is a 50% purely production solution that facilitates production / repair / supply and another 40% - a marketing ploy.
      Combat effectiveness takes no more than 10%
      And so, within these 10%, the maximum that you need to carry with you is a short barrel with a handle, to a machine gun. Everything. Basic automaton one (two can be used - for special equipment, so as not to change the caliber).
      The configuration of the main armament will most likely be chosen once and for a very long time.
      Any unnecessary modules are stored in the weapon.
      Fighter does not solve or change anything! Only the commander can decide to change the modules - if necessary - and this will be done in the place of permanent deployment, with the subsequent correction of the STP or the weapon's shooting.
      The decision to change the caliber is generally the prerogative of the army command - with a subsequent change in the ammunition supply schemes.

          The articles are very good and literate.
          But they do not take into account a number of points.

          Previously, combined arms combat prevailed. When the Cascade set off its first operations, and the guys from its composition took part in the assault on Amin's Palace, it also looked more like a combined arms battle than a special one. operation.

          Now, everything is fundamentally changing
          Even in the FSB special forces, there is more and more division into highly specialized operations.
          The assault on a house, an airplane, a ship, sabotage actions are like doctors. Anyone should know what hemoglobin is. Anyone should be able to measure blood pressure.
          But a person who treats hemorrhoids should not undergo heart surgery.
          This is a logical stage in the development of medicine as a field of human activity.

          And military science comes to the same thing.
          Therefore, the coeff. the mentioned 1,5 is applicable for conscripts.
          And for specialized divisions it is no longer.

          It's like the difference between vocational school graduation or becoming a doctor of science.
          3 years of study or 23.

          These units have a fundamentally different level of tactical and intra-command interaction.
          And the effectiveness of a weapon is measured differently.
          A lot of tactics are built around the machine gun.

          And we just don't have a 5,45 with tape feeding.
          And this is an opportunity to avoid multiple reloads - the time during which the team can move and take more advantageous positions.
          And the position gives much more than the difference in the performance characteristics of the weapon.
          A lot more.

          Ideal of course standardized with store food. Such options seem to have been considered, they are harder and more complicated, but it is possible.

    There is an eternal rule: “The more complex the system, the more it is susceptible to breakdowns.” And also more difficult to maintain. And modularity is a fashionable hobby.

    In view of this, it is impossible to create one machine gun for the entire army.
    It is hardly reasonable to create for the entire army and the same type of units, and, even, as part of one assault group, there will be specialization in weapons.

    It is a pity that in his "refutation", the author did not hear what was said earlier in the comments.

    I have always disliked the logic of clean shooters from the shooting range, and players of various computer shooters. There will be no "modular" weapon more reliable and better for dirt and blood, for real war. Rather than carrying spare parts for the "transformer" with you, the same commando will take more cartridges for a normal, reliable machine gun, for the task for which the group is being promoted.

    Even when "based at outpost "Charlie"", modularity is hardly a blessing. When changing ammunition, you will have to change not only the barrel. In principle, on the same" base ", it is better to have an AKM for 7,62X39 and AK-74 with 5,45X39, other various weapons, of which better choose than "transformers" with a bunch of gadgets.

    Modularity, as a good base for various weapons, is one thing, constructors-transformers, quite another. Therefore, there was a division between what is good and evil.

    Perhaps "modular weapons", like weapons "printed" on 3-D printers, will fill the market and be in demand, but, just for the pros, they are the least suitable. The universal will always lose to the specialized one, especially, this is true for sniper weapons.

    Hammer Afghanistan ambush on YouTube and see what kind of patrols.


    And where is the patrol? A common ambush when clearing in villages or on the road.
    Quote: Alexander Vorontsov
    Squad armament should be designed for everything and always. At those distances, as in most videos, a submachine gun is enough, and not a large-caliber anti-material rifle, especially since the enemy is without armor. On the way, I did not see patrolling on foot. Maybe I should have looked for something else in the video. And what one should admire is the fact that they yell at each other and look into the optics.

    It's impossible in principle

    In principle, everything is there ... or rather, in principle, everything is there, when moving a squad in armored vehicles along the road, there is either an AGS, or an automatic cannon, or a large-caliber machine gun. The standard compartment has a sniper, machine gunner, grenade launcher or MANPADS operator. And in densely built-up conditions, as in Afghan villages, it is more convenient for special forces to use a good pistol, such as APS, than a drin in the form of a machine gun, since the clash occurs at a pistol shot distance - the mobility and the rate of change in the direction of fire is incomparably higher than that of an assault rifle or machine gun .. It was written on the forum that the Azerbaijani special forces took Shusha using pistols, and jump over the fence, and jump from a height, and climb the steep cliffs with a pistol more conveniently. The correct choice of weapons resolved the issue of taking the Shushi fortress, and the pistol can be duplicated, the burden is not large, but the reliability of the weapon increases significantly. Only there is no video, that's what would be interesting to see about the new tactical findings of the Azerbaijani army. And modularity was present there ... in the form of knives - in every joke there is only a fraction of a joke, yes Nikolaevich I?

    This article and the previous one are very sharpened on small arms as such, having opposite opinions, and clashing like black and white, not taking into account other possible options and in both cases, in my opinion, behind the times.

    Modularity is good or bad, in my opinion, such reasoning is relevant when we are talking about police special forces. In the case of army special forces, from reconnaissance to airborne assault units and Special Forces units, I think it is much more important than a system for providing a highly trained or professional fighter with up-to-date information.

    If you have in your hands even the most modern and best model of small arms, albeit modular, albeit non-modular, and the enemy, being armed with a Sudaev submachine gun of the Great Patriotic War, will have a qualitative superiority due to better equipment with information about the battlefield, communication and control systems, navigation , night vision devices and sighting system, etc. Your excellent unit of small arms, modular or non-modular, will become the prey of the enemy, and your ears will be a trophy.

    The cheapening and dissemination of digital technologies, micro and nano electronics, the possibility of spreading and creating relatively inexpensive and mass-scale devices for aiming, targeting, ammunition from relatively simple ones with a programmable fuse to the most complex "smart ammunition" by today's standards, will significantly change the ways and course of wars.
    Let's take the usual and still far from the most common "accessory" in our army. If the anti-splinter goggles of today will become tomorrow, and the samples are already there, a means of information, lighting the situation, aiming, etc. this is already an advantage. In these conditions, the requirement of reliability with the necessary or sufficient accuracy will be presented to small arms, as now.

    In the meantime, we would at least have a normal tracer ammunition, otherwise while we live to see the electronics and systems of the future, our squad leaders, castles and platoon commanders will continue to become targets for target designation.

    I have a few questions to the distinguished author:
    1) Tell me, how do you understand the actions of the MTR in wartime? Until today, I believed that the main activity of the MTR group is reconnaissance and target designation behind enemy lines ... What's the difference with what an individual fighter is armed with in such a scenario, which does not imply fire contact in principle? Maybe you mean counter-terrorist groups in your rear, with stationary warehouses, rembases, shooting galleries, gunsmiths? If so, what does this have to do with the sun?
    2) When changing the barrel for a different cartridge, is it not necessary to bring the weapon to normal combat? How, or rather where and at what time, to do this if the order must be executed immediately? Moreover, what should a fighter do if the transition to a different caliber must be performed directly in battle?
    3) It is no secret that the MTR fighters fire "intuitively" they purposefully develop this weapon skill. How to apply this trained skill, if today you go on a mission with a "barrel" under 7,62x39 (clearing the village), tomorrow they sent you to shoot with "fives" (patrol in the "fields"), and the day after tomorrow we have an exit to the mountains with alteration under 7,62x54R? The ballistics of ammunition and their action on targets (especially behind cover) are completely different in these three scenarios.

      As wide as possible.
      Special operations of troops are blah blah blah ... events carried out by specially designated, organized, trained and equipped forces, using methods and methods of combat that are not typical of conventional forces

      And as I wrote above, there is a tendency towards ever narrower specialization.
      There are many tasks for this.

      2) When changing the barrel for a different cartridge, is it not necessary to bring the weapon to normal combat? How, or rather where and at what time, to do this if the order must be executed immediately? Moreover, what should a fighter do if the transition to a different caliber must be performed directly in battle?

      MTR, among other factors, the level of planning differs.
      And here we must admit that we had some elements since the times of the USSR.
      But as a system ... the United States has gone far ahead.

      For example, it is normal for the MTR if already 4 years ago (I suppose. It's bad if this was not done) a group was assembled that planned and prepared to perform tasks on the territory of Ukraine.
      They are free to spread the Ukrainian language among themselves. Know the area. For them, sets of uniforms of the Armed Forces of Ukraine, etc. have been prepared.

      if the order must be executed immediately?

      Again, if the command was preparing before ... as in the example with Ukraine.
      There is no problem in taking pre-prepared weapons, putting on pre-prepared clothes and going to fulfill the pre-prepared plans. Having several scenarios that have already been worked out.

      If they are caught with their pants down in the toilet, what are the options? Go to war with what is. But here the question arises - is this exactly what the MTR was created for?

      You don't need to switch to another caliber in battle. You need to go before the fight.
      Shoot weapons the same way before the fight. The fighter must maintain skills anyway.


      Quote: DesToeR
      It is no secret that the MTR fighters fire "intuitively" they purposefully develop this weapon skill.

      Here is also a curious moment.
      I am not very much in fire training, but at one time I was at the top world level in "diving" training. Including training in the United States according to methods directly borrowed from their military units.

      When you practice a skill, it’s training in movement patterns. You are sitting in a car ... and if you throw your hand without looking and hit the gear lever, you are familiar with its shape, actuation force, sound and tactile sensations ... you can switch your attention to the outside world.
      Your outfit becomes an extension of your body.

      This is to the question that well, we have AKSU, Ak with lengths of 300 and 400 and RPK.
      Why AUG has 4 replaceable barrels?

      If a person has not achieved the sensation of the continuation of the body ... then it makes no difference to him.
      It makes no difference to me for example. I will shoot from one on "satisfactory". What's on the other
      And for a person who actually spends hundreds and thousands of hours on shooting .... and who has his "carcass" with a handle that he chose for himself, with a butt that takes into account his anthropometry. With his preferences regarding sighting devices. It will make a difference for him.

      Have you ever noticed how weapons bloggers handle guns?
      People who with weapons well ... worked. When they are given a sample, they cannot always switch the fire mode.

      Therefore, ergonomics means a lot for "intuitive shooting".

      And changing the barrel - there is no problem, change it, shoot it.

      Ballistics change dramatically at long range. At the same time, the fighter must still be able to correct the distance. Therefore, intuitively shooting at long distances will not work in any scenario.

How much will the number of vehicles of at least a division increase, how will this affect the stretch of communications, how will the average speed of the convoy on the march change, how much the daily rate of consumption of fuels and lubricants will need to be increased, what will be the number of service personnel. How to protect all these warehouses with "finished products", how to cover the elongated columns from the air? This is a bunch of additional activities flying within the framework of the Armed Forces in a round pretty penny. And plans are good, only in war they are often good before the first shot.

              What allows you to use the term "indulge" in relation to these professionals?

                This is a NAVY SEALS fighter

                He is an EXTRA-class professional.

                Why go far - to see our fighters from Alpha, FSB, GRU - they are all hung from head to toe, and in all interviews they say directly - how they would like to have domestic modular weapons, like SCAR, so that they don't have to dance with a tambourine when customizing your weapon.
                In fact, all the criticism of the local mother's experts comes down to the fact that they (navi sils) are completely incompetent

                Most (perhaps even overwhelming) "couch critics of everything and everyone" at VO are either people unfamiliar with the actual use of military weapons, or those who last held AKM in their hands, during a deadline.
                Therefore, they all "did not read, but condemn." They don't want, you understand, to carry 3 barrels, 2 bolts, and a supply of magazines and cartridges for them. hi

    It's very funny when they say that modular weapons are expensive. Well, yes, the Belgian SCAR is certainly more expensive than the AK-74M, but the price difference is for a different reason. And the Cold War showed that an army armed for a war with another superpower at any time can go to war in some Vietnam, and there it will need other weapons, and re-equipping the army with new machine guns is much more expensive than simply replacing all the barrels, magazine receivers and shutter / shutter mask. And about, the characteristics that supposedly fall in modular weapons, well, there are many types of modular weapons, and that, they all have low characteristics, but not even high, because a good weapon or a bad one depends on how it was designed and made at the factory, and not from that and not only from the fact that half of the parts are replaced on it in half an hour, with a standard set of tools.

      People who write about reliability in this thread do not quite understand the meaning of what they write.
      If you look at it, the cannon has the most primitive design. Or a musket. Muzzle. Charge. Projectile.
      But weapon designers, for some reason ... constantly complicate weapons.

      Those. if you read those who drown for simplicity - you just need to disperse all gunsmiths.
      There is an AK-74 - everything. What else does?
      They cannot understand that solving engineering problems is an ordinary job of designers.
      And the story with the AKS-U, when a 5,45 mm barrel was made under 200 ... it's just the finish.

      In the article I tried to give an example with Afgan.
      But as the author of the previous article, not knowing the real prerequisites, he preferred to come up with - the only reason is the desire of manufacturers to get rich by releasing "crap".

        Yeah, but also very much deliver statements that "modularity introduces additional variety into the range of army weapons"
        Yes, against the background of how many types of MBTs, fighters, helicopters, army vehicles (where Omerike is there) - it sounds very funny. And this despite the fact that modularity greatly facilitates production, maintenance, repair and supply.

          The buzzword is modularity, or a fashionable model, or something else, and what's more, it's a trend (probably from the word tryndet), ... why introduce new concepts if you can use old ones - standardization, typification, unification ... the list seems to be exhaustive, and if here we are talking about a kind of "modular" designer with which you can change the characteristics of small arms depending on the tasks set, then they would say so, for example, in the department, all weapons consist of parts that are unified among themselves and the fighters can be right before the battle on the knee, change barrels, calibers, sights, bolts.
          I think the musicians would also need a "modular" musical instrument, so that before the concert it would be possible to rearrange the violin soundboard to the double bass, and build a drum from the double bass, in accordance with the score

    Again, I have old complaints about modular weapons:
    1) a rare machine gun has sights directly on the barrel, which means that changing the length of the barrel each time will require bringing the weapon to normal combat;
    2) an additional barrel takes up space: isn't it wiser to spend this space on ammunition?
    3) a longer barrel with the same technology of its production will not provide better accuracy, and therefore will not provide a higher probability of defeat, then what is the point in it?
    4) modular weapons are heavier than conventional weapons, which complicates their operation;
    5) long-range shooting requires separate training, installation of optics and a "long" barrel will not allow the shooter to shoot more accurately without the necessary skills.
