Comparative characteristics of the fragmentation effect of F-1 and RGD-5 hand grenades

Each ammunition has its own purpose. In service with the Russian armies The most common hand grenades, known since the Soviet era, are the F-1 and RGD-5. The first is considered defensive, and the second is offensive.

To have an idea of ​​​​the possibilities of using these ammunition, we will need a comparative description of the fragmentation effect of hand-held anti-personnel grenades F-1 and GRD-5.

An important characteristic of ammunition is the distance at which the probability of hitting the enemy with at least one fragment is one hundred percent. If a person 178 cm tall stands facing forward, then he is guaranteed to be hit by the explosion of an F-1 grenade at a distance of 4,15 meters.

The RGD-5 has a higher probability of damage, but its explosion produces larger fragments. The same figure for it is only 3,05 meters.

Externally, these two grenades cannot be confused. F-1, informally called “limonka”, has a specific ribbed body surface. This design was originally intended not for better separation into fragments, but for a more convenient grip or fastening if it is used for mining.

There is also a difference in the material of the case. In F-1 it is made of cast iron, and in RGD-5 the material is softer low-carbon steel. That is why its body during the explosion was divided into a smaller number of larger fragments, compared to the F-1. And since the percentage of TNT relative to the metal in RGD-5 is higher, the fragments during the explosion of such a grenade fly at a higher speed than those of the F-1.

Thus, RGD-5 has a greater damaging effect, but a lower probability of defeat than F-1.

Well, I remember the NVP textbook :))

The article is for the EG and OBZh generation; for the more ancient ones, this was all “chewed on” in NVP lessons and reinforced in conscript service (and then - as one was “lucky”).

as it is said in one movie: “But the hands remember”...

[Uncle lee]

Quote: Leshak

“But the hands remember.”

Sometimes you pull for a check-
The grenade explosion explodes!
And I hold her hands on her -
And nothing happens to her!

[Alekseev]

The article... How to put it more correctly, is not particularly necessary.
The author, instead of writing theoretically about how fragments fly, should be forced to use the F-5 instead of the RGD-1 in a well-known military exercise (throwing a grenade in an offensive).
He will understand how the fragments fly immediately and, if he is lucky, will remember the difference between hand grenades forever.

[Leshak]

God forbid, of course, but it is very possible that nothing more will be written.

[militarist63]

The fact of the matter is that this is all... in the article - theoretically hypothetical blah blah blah... And how exactly did they calculate it!!!! 4,15 meters, 3,05 meters.... It was necessary to calculate more precisely, down to the millimeter In fact, you cannot predict in advance how the fragments will fly! And then he says something like:

An important characteristic of ammunition is the distance at which the probability of hitting the enemy with at least one fragment is one hundred percent. If a person 178 cm tall stands facing forward, then he is guaranteed to be hit by the explosion of an F-1 grenade at a distance of 4,15 meters

Come on! Let me tell you a case from real practice. At the end of 1988 in Afghanistan, an incident occurred in our regiment. In the 2nd Battalion, one evening, a senior soldier got drunk and came into conflict with the battery sergeant major... The sergeant major went into the battery officers' room to report to the battalion commander...., and this stoned soldier then threw F-1 into the room. .. The sergeant major and the officers were near the door, so they managed to quickly jump out of the room. The grenade exploded. But at this time there was only one officer left in the room - a lieutenant who had recently arrived from the Union as a replacement and was sleeping peacefully on the second tier of the bed. The explosion woke up the lieutenant and he (stunned) jumped out of his bed and ran wildly, in a state of shock... Well, they reacted in time and caught him, otherwise he would have run away outside the outpost, into the night "green".... F-1 rushed off, just about 4 meters from the bed with the lieutenant. But there's not a scratch on it! Somewhere 2 meters from the explosion site there was a Sharp double-cassette player on the table with its handle raised and covered with a plastic bag. One fragment broke the carrying handle in the middle and cut the polyethylene with dust. The tape recorder remained completely intact (except for the handle) and in working condition.
It further states:

The RGD-5 has a higher probability of damage, but its explosion produces larger fragments. The same figure for it is only 3,05 meters.

When the officers and the sergeant-major rushed out of the room, in the corridor of the barracks a stoned soldier began to threaten them with an RGD-5 grenade (without the pin). The battery commander tried to take the grenade, but during the struggle the grenade fell out.... The soldier managed to drop into the officer's room at the last moment. The grenade exploded less than 3 meters from the battalion commander. I received one fragment in the heart area. The fragment stopped literally 1-1,5 cm from the heart. They bandaged it. Because The operation is complicated, the doctors decided to send him to the Union, to Burdenko. Nothing, he boarded the plane cheerfully, under his own power...

[alexoff]

So the author of the channel said all this in the video

[militarist63]

The author of the channel wrote crap! just think about it:

will be guaranteed to be hit when an F-1 grenade explodes at a distance of 4,15 meters.

or into this:

The RGD-5 has a higher probability of damage, but its explosion produces larger fragments. The same figure for it is only 3,05 meters.

Why is the precision discreteness so rough? Why, for example, not some 4,151357 meters and 3,05169 meters?
In fact, with grenades it’s a matter of chance! There is no predictability (let alone a guarantee) of how the grenade body will break and how the fragments will fly! You can stand 2-3 meters from the explosion (both models...) and not get damaged. The most reliable thing (for a guaranteed hit with a grenade) is to cover the grenade with your torso! Let me note, just the torso and without body armor!

[alexoff]

So it is clear that we are talking about a fairly high probability, the grenade may not explode at all, it may fall on a fighter, for example, with a fuse and nothing will hit him. These are numbers from tests where a vertically placed grenade was blown up and holes were counted in sheets of Whatman paper hung around at different distances. It makes no sense to say that “there is a 1%” chance that 0 fragments will hit a fighter standing two meters away, since a 100% probability in war does not give anything, even a dagger’s warhead may not explode

[Arnok]

Many of the “USE Generation” are already over 30 - 40 years old, if that. Let's just say that there aren't many "Generation NOT USE" left. Even though I’m still before the Unified State Exam, I have an extremely negative attitude towards such discrimination.
Now the people you so disparagingly call are fighting and working at the front and in the rear.
Shame on you?
And the children who successfully pass these exams, who study well, try hard, are they also bad, “wrong”?
Where does this attitude come from?
With this approach, we will not sell the elephant, comrades.

[Evgenijus]

This is the first time I’ve heard about mining with an F-1 grenade (we know about tripwires). About the guaranteed defeat of the enemy with this grenade at a distance of 4 meters, this is generally information for factory testers, and not for a soldier in a trench. If the enemy has reached your trench at this distance, then it is too late to throw a lemon. This is unnecessary information about this distance. The author has no information at all about offensive grenades. What kind of “offensive” is this? At one time, we were taught that when using an offensive grenade, it was necessary to move the bag with the gas mask to the “front” position and boldly throw the grenade into the enemy’s trench, which you were ordered to capture. The accuracy of the throw is not always successful, then this bag with a gas mask saves you from fragments of your grenade, from damage to the hip part of the body. It is precisely this defeat of a fighter that immobilizes him on the battlefield. This grenade is used precisely on the offensive.

[Doctor]

The question is whether 2 types of grenades are needed. F1 has been going on since the First World War. It's redundant, IMHO. Rgd, on the contrary, is rather weak.

[invisible_man]

An important characteristic of ammunition is the distance at which the probability of hitting the enemy with at least one fragment is one hundred percent.

It would be nice to write that in order to cause any significant damage to a person, you need a fragment weighing at least 2 grams. But it’s gratifying that when describing the F-1 they didn’t remember about the mythical 200 meters :)

[Ash]

Up to 200, which is both 5 and 50 meters. RGD has up to 30. This is from the school CVP course. But in fact, in 96, at our shooting range, an ensign from a special forces company was making something incomprehensible from 4 RGDs, 15 meters from the tower. Something went wrong, he jumped back 2 steps and collapsed, as a result on the tower minus one glass from the blast wave, he had a scratch on his leg and a hole in his pants, 3 meters from the epicenter. If I hadn't seen it myself, I wouldn't have believed it.

[Andrei from Chelyabinsk]

Yes, the ensign is definitely from the special forces

[invisible_man]

Well, you should have written “up to 1000 meters”, why waste time on trifles? :)

[Monster_Fat]

I read somewhere where the phrase about being hit by fragments of an F-1 grenade “up to 200m” came from - supposedly at this distance, during testing, parts from the fuse were found.

[faterdom]

Where is the Russian Geographical Society? Which fuse is not UZRGM, but a little different? And RG-42?

RGO, RGN have not gone away; they are still produced, but production volumes leave much to be desired. Currently, such grenades are widely used by various special forces.
UDZ fuse (“Shock-remote fuse”). As the name implies, it is capable of detonating a grenade both a few seconds after being thrown and when it hits any surface.
RGD-5 and F-1 are easier to manufacture and, as a result, cheaper.
There is a huge stock of old grenades.

[Dmitry_Likhoded]

I don’t know where RGO and RGN are produced, they are produced at the front from the 80s, others have not come across. Soldiers practically never use these grenades, since the plastic of the UDS fuses crumbles and breaks due to age, or the fuses do not fire.
The best of those that came across were captured American M67 grenades. Much more powerful than ours, the fragmentation field is larger, the fuse is silent.

[acetophenone]

Children's garden - pants with straps...

[NSV]

Current material!!! Right on the topic of the day!!! the author, these truths were set out back in the 80s in the Instructions!!! Only there was also RG-42! The point of such an article on a site where the bulk of subscribers are officers!!!

[bya965]

Lack of education. The author of the article also forgot the shock wave, especially when used in a confined space. In lemon it is much higher. You can also remember about the temperature effect.

In general, all uneducated youth and journalists talk only about the quantity of explosives, but for a landmine, the amount of iron on that explosive is much more important and the detonation speed of the explosive itself and fragments are not the main thing here.
An anecdote on the topic of undereducation:
1) According to the manager:
- The computer doesn’t turn on - I’m calling the admin. The admin comes, raises his hands to the sky, mutters unintelligible words to himself, turns my chair 10 times around its axis, kicks the computer - it starts working. He again raises his hands to the sky, mutters something, and leaves.
2) According to the system administrator:
- I come to the user - this one was spinning so much in his chair that his power cord got wrapped around his leg and jumped out of the computer. I swear to myself, unravel, push the computer further under the table with my foot, turn it on, and leave.

[Parvis rasulov]

A little clarification of the F 1 grenade when detonated, sometimes it is not all but partially destroyed, and often the lower part of the tray flies off in a whole piece and causes damage in a larger piece. Regarding the RGD, it is much more effective than the F-1 when detonated and can hit a person who is lying on the ground than the F-1 grant, but the wounds inflicted are often not deep wounds, and the worst thing is that numerous small fragments remain in the body, which are not removed but remain in the body.

[Vladimir_Tver]

We were taught tactics (1990-1992) - I threw the RGD and covered my face with the machine gun forward. The rest was covered with armor. Thank God I never had to try this method.

[TwilightElf]

what's in the head...if INITIALLY...one grenade is for OFFENSIVE and the second is for defense)) but in principle you can also hammer nails with a microscope

[Jacques sekavar]

The destructive effect of grenades depends on the accuracy of the throw and dispersion of the fragments - their density and direction, and the direction of dispersion depends on how the grenade “lands”. As in tests, that's one thing. In reality, this practically never happens; it can land in any way - vertically, at one angle or another, horizontally. The scattering of fragments will depend on this - in a circular direction, at an angle to the horizon, or if it falls “lying”, the sector and probability of damage will accordingly be different. And most importantly, in a grenade battle they use what they have, and not what is prescribed.

Comparative characteristics of the fragmentation effect of F-1 and RGD-5 hand grenades

It seems that the person has no idea at all on this issue or that Russian is not his native language and he does not understand the meaning of Russian words and sentences made from them. How can you compare ammunition with completely different purposes and damaging effects? One grenade is defensive, used only and exclusively in the presence of cover, the second is offensive, mainly for a confined space, implying almost immediately following it into a trench or room while the enemy is stunned or shell-shocked. Why are there such articles on this seemingly serious and adequate site, and even at such an amateurish level? You don't have to read beyond the title.
