How to arm tank support vehicle
First of all, you need to remember the goals and objectives of BMPT / BMOP. Such a technique, as its name implies, is intended to provide fire support to tanks or infantry. The main tank is not always able to fight tank-dangerous targets, and therefore their destruction is assigned to the infantry. However, in some situations, the infantry can not accompany the tanks and help them. It is in this case that BMPT is needed - a special vehicle with powerful protection and advanced weapons, capable of detecting and destroying grenade throwers, anti-tank complexes calculations, as well as light armored vehicles or some fortifications.
Thus, potential targets for weapons BMPT are manpower and a significant part of the combat vehicles for various purposes. At the same time, depending on the specifics of the current situation, the fire support vehicle may be able to attack tanks or field structures. All this places special demands on its weapons and fire control devices.
Bullets and shards
Despite the development of defenses, infantrymen with grenade launchers or portable anti-tank systems are still one of the main threats to tanks and other armored vehicles. Their weapons can, at a minimum, damage the tank and interfere with its operation. Thus, BMPT should be able to effectively defeat “soft targets” that threaten armored vehicles. An obvious means of dealing with such threats is small arms and automatic grenade launchers.
In the near zone, at distances of at least several hundred meters, an effective anti-personnel vehicle is a machine gun of normal caliber. For example, the Russian BMPT "Object 199" / "Terminator" carried one PKTM machine gun with an aimed range to 1500 m. The placement of the machine gun on a stabilized unit and the presence of a fire control system with advanced optics made it possible to realize the full potential of such a weapon. The twin gun mount system on the Terminator allowed the weapon to be raised 45 ° above the horizon, which in a known manner increased the area of shelling of the machine gun and other systems.
The bullet's trajectory limits the combat qualities of the machine gun, preventing it from hitting targets behind obstacles. To increase the anti-personnel potential of BMPT / BMPPs, you can use automatic grenade launchers that can carry out mounted shooting and literally throw ammunition over obstacles. Grenade launchers of type AG-17D are used in several domestic projects of tank support machines. With their help, it is proposed to hit manpower, unprotected buildings and lightly armored vehicles at ranges up to 1500-1700 m.
It should be noted that in the field of "light" weapons there are disputes and improvements. For example, the Russian “Terminators” of the first versions had both a machine gun and a pair of automatic grenade launchers. In the future, the grenade launchers were abandoned for reasons of crew reduction and optimization of internal space. Foreign samples, such as the newest Chinese BMP QN-506, may not have grenade armament at all and can only do with a machine gun.
Artillery fire
The obvious way to bring the range of destruction of tank-dangerous targets to several kilometers is to use artillery weapons. Equipment BMPT / BMOP tank gun or other medium-caliber gun does not look optimal, and therefore this technique should be equipped with small-caliber guns. Tools caliber 30-40 mm have the most successful combination of firepower and size, and also do not impose special requirements for the volume of large ammunition.
Russian engineers for a long time came to the conclusion that it was necessary to use two automatic guns at once. A pair of 2А42 X-guns caliber 30 mm provides a significant increase in firepower, while maintaining a reasonable size of the ammunition. In addition, the installation with a pair of guns is characterized by increased survivability: damage to one gun allows you to continue shooting.
An interesting fact is that foreign engineers when developing new concepts and real samples do not always use Russian ideas. As a result, their equipment carries only one small-caliber gun. This simplifies the design of the combat vehicle, but at the same time leads to understandable consequences in the context of firepower and combat survivability. However, foreign technology, such as the Ukrainian BMPT "Guard", may have a couple of guns.
The 30-mm automatic gun is capable of striking manpower or unprotected equipment at distances up to 3-4 km. At shorter ranges, it also turns out to be a means of dealing with light armored vehicles and various structures. Vertical guidance in a wide sector allows you to attack low-flying slow air targets. Thus, artillery can be considered perhaps the most important element of weapons of BMPT, capable of hitting most of the characteristic targets. At the same time, as events and trends in recent years show, it should be developed in a certain direction.
Light and medium in mass armored vehicles armed with ATGMs pose a serious threat to tanks - quite a few armored personnel carriers or infantry fighting vehicles from different countries now correspond to this definition. To date, most of these machines have protection from small-caliber artillery shells, most often 30 mm caliber. Thus, BMPT / BMPP with an 30-mm gun can no longer be guaranteed to hit enemy equipment before it reaches the line of return fire.
The solution to this problem can be an increase in the caliber of weapons. Now in our country are creating new combat modules with 57-mm automatic cannon. It is possible that the next generation of "Terminators" will receive such weapons, and with it the ability to defeat almost all tank-dangerous objects - with the exception of tanks.
Guided missiles
Working in the same battle formations with tanks, the fire support fighting vehicle has all the chances to face the enemy’s heavy armored vehicles, and this must also be taken into account when forming its armament complex. As already mentioned, the installation of tank guns on the BMPT does not make sense, therefore, to fight against tanks it is necessary to use other weapons. A reasonable response to such threats are guided missiles.
Russian tank support vehicles are equipped with the Ataka anti-tank missile system and are capable of using several types of missiles. Ready-to-use ammunition consists of four missiles transported on the sides of the turret in transport and launch containers. The Attack complex increases the range of target fire up to 6-8 km. Depending on the model of the missile, the tandem cumulative warhead is capable of penetrating at least 850-950 mm of homogeneous armor behind dynamic protection.
Similarly arming machine "Guardian". On its tower four TPKs are transported with missiles of the Bar' перевозr complex. The firing range they declared at the level of 5 km. The tandem warhead is said to be capable of penetrating more than 800 mm of armor for dynamic protection.
Chinese engineers in their project QN-506 used a different set of weapons. This armored vehicle is equipped with a pair of large containers with rocket weapons, which use two types of missiles. First of all, the Chinese BMPT / BMOP can use QN-502 guided missiles with a range of up to 6 km. Also, unguided rockets QN-201 caliber 70 mm can be used against ground targets. Launch rails for unguided rockets are placed on some installations with TPK anti-tank missiles.
Other well-known foreign projects and concepts also provide for the use of guided missile weapons, but from this point of view they are not of particular interest. Missiles are regarded as a “standard” addition to other weapons, and no radical innovations are envisaged.
Arms control
Even the best weapons will not be able to show high performance without effective controls and guidance. From the point of view of possibilities of observation and search for targets, BMPT should not be inferior to modern tanks and therefore needs appropriate means. The commander must have a panoramic sight, the gunner needs his own aiming devices. You must have a day and night channel, as well as a means of measuring distance. In the future, tank support vehicles may also receive other means, such as radar stations or reconnaissance unmanned aerial vehicles. Some new models already have similar equipment.
As development progressed, domestic BMPTs received the entire core set of weapons monitoring and control tools. At the same time, the specific composition of the armament complex led to the need to create a completely new fire control system capable of controlling barrel and missile weapons of all types. The standard equipment of the Terminator provides observation of the entire surrounding space with timely detection of targets and subsequent targeting of weapons.
The Chinese project QN-506, according to known data, involves the use of similar equipment, but at the same time offers an expansion of capabilities through completely new components. Such a BMPT should carry a light unmanned aerial vehicle with a camera on board that has a working radius of 10 km. The presence of the UAV provides reconnaissance at a long distance from the combat vehicle and, as a result, increased crew situational awareness.
Fire in all directions
The unobvious, but important parameter of a tank support combat vehicle is the ability to fire in different directions, including with simultaneous firing from different weapons at several targets. Modern BMPT / BMIP have similar capabilities of this kind, allowing to solve basic combat missions. At the same time, certain problems are possible.
Russian "Terminators" of all modifications are equipped with a full-turn turret and panoramic sights. Thus, the crew can detect the target in any direction and then attack it with a machine gun, cannons or missiles. If the target is in the forward hemisphere, then some variants of our BMPTs can also hit it using grenade launchers. In appropriate situations, the target in front can be fired at once in several ways. With only a turret and no exchange rate weapons, firepower decreases slightly, but the pickup sector remains the same.
You also need to consider the number of simultaneously fired targets. Different situations can arise on the battlefield, and in some one BMPT will have to attack several different targets at once, including in different directions. Some modern combat vehicles are capable of solving such problems, while others are inferior to them in this.
The old modifications of the Russian Terminator had both a turret with weapons and a pair of automatic grenade launchers on their own installations. The architecture of the tower and SLA allowed the simultaneous use of guns, machine guns and rockets for only one purpose. At the same time, a pair of grenade launchers, which had their own sighting devices and autonomous weapon systems, could attack two other objects. Late modifications of Russian BMPTs were left without grenade launchers. Accordingly, they lost a couple of target channels and related opportunities.
Future and development
The concept of a tank support combat vehicle / a fire support vehicle cannot be called particularly popular. New projects of this kind appear regularly, but real samples are rarely built, and most of them are created by just one country. Nevertheless, the military of different armies show some interest in the proposed ideas, and this is the reason for the continuation of the development of the whole class and the emergence of new projects.
Apparently, in the future, BMPTs will change, but their development paths are still difficult to predict. Most likely, the main way to modernize such equipment will be the transfer of combat modules with weapons to new chassis that meet current requirements. It is also possible to upgrade the weapon system. First of all, it should follow the path of using new types of barreled weapons, missile systems, etc. New products will improve the range and accuracy of shooting. It makes sense to further develop fire control tools, including with the addition of existing systems with new devices.
However, the development of the entire class of BMPT / BMIP is limited by objective factors. For one reason or another, this technique is not popular. The lack of orders leads to a lack of competition and, as a result, to the absence of the need for active development of the direction. Nevertheless, BMPT is still coming into service in some countries, and this stimulates their development. The improvement of technology continues, and in the future we will be able to see again the results of such incentives.
