Funny story... In basic training for the US army, we had grenade training. We used training grenades that had the fuse, but no explosives and a hole in the bottom to allow gases to escape. We had multiple training scenarios we had to train on. One was tossing (you don't throw a grenade) into a mortar position. I had removed the thumb clip, twisted and pulled the pin, then tossed the training grenade at the position. It had spun, as I was used to putting spin on football after playing for years, and landed bottom first straight down the tube of the fake mortar. Once the grenade went off, the gasses launched it back out and flew almost 50 meters down range. We had to stop the exercise and find the hull, as they are reused and must be collected. My DS said it was the weirdest thing he had ever seen in his career. 5:05

[@NOTSOSLIMJIM]

@@DrSardonicus ok... I'll try to explain this as best as I can. You don't throw a grenade like a baseball. There are two reasons for this. One, you want to toss the grenade from behind cover. If you were to throw it like you traditionally think of throwing, you would have to be upright and your head exposed. Two, grenades have a 3-5 second fuse. If you throw it directly at a position, it can get there too quickly and have time to be tossed back. By tossing it slowly on an ark, it has a longer travel time. As for what is "tossing" or lobbing, it is overhead "throwing" of the grenade. This allows the individual to be able to toss it when laying in their side only exposing their arm, while standing and not exposing their head, or even underhand into doors when breaching.

[@FlyingFox333]

@@DrSardonicus Your right, they are interchangable terms. Tossing is usually an underhanded throw, like the initial action of a tennis serve. Throwing is a more general term but usually infers an overhanded throw that imparts more energy to the object then a toss would.

The Tiger tank was equipped with a demo charge for insertion into the barrel when abandoning the tank. Most crews discarded it because the commander didn't want an explosive charge stowed right next to him (Otto Carius, for example, carried a bottle of schnapps in the container for it instead). Without the charge, the way they used to disable the gun was to drain the recuperators then fire a round. This would cause the gun to jump its trunnions and destroy the recoil mechanism. You can see this in some WW2 photos of abandoned Tigers. In Germany, I once saw a Chieftain tank deliver cans of beer to infantrymen in their fighting positions, by sliding them down the barrel.😁

[@a.karley4672]

An ex-military friend told me that, while returning to the UK from Germany, they stocked up on a certain brand and bottle size of Schnapps which fit very snugly into the tank barrels without a Customs-alerting rattle. Duty-free fags by the ammo box full, with a decorative layer of belt ammunition ... Very likely, the Customs knew all these tricks (some ex-soldiers join them, after all) and just didn't care.

[@EuroScot2023]

The thermite grenade down a barrel was a standard technique used to disable enemy guns in WW2. It was usually done when an artillery position had been captured but there was a likelihood that the enemy could recapture it. It would work just as well with an abandoned tank which might be recovered to make it unusable. As others here note though, it would be a likely suicidal thing to attempt if the tank was manned and operational.

[@501Mobius]

The stated way in the M60 and early M1 manuals to disable a tank that the crew abandoned was two thermite grenades down the barrel.

[@robertp452]

A thermite grenade is very different than a fragmentation hand grenade designed for use against personnel. A frag grenade wouldn't destroy the barrel, much less the tank. Thermite grenades are incendiary grenades. They don't explode, they BURN white hot and melt or burn through whatever they are placed on. They are used to destroy equipment that is being left behind so that it can't be used by the enemy.

[@CrizzyEyes]

Thermite grenades were built for this exact purpose. Thermite burns right through metal in a slow controlled reaction; it isn't an explosive. A frag grenade, while probably not good for the barrel and would fill it with some shrapnel, wouldn't destroy the breech block. The reason why you see the tank erupting in flames in the video from Syria is because the grenade went through an open breech block and blew up the ammo in the crew compartment

[@robertp452]

Exactly, but the question is referring to frag grenades, not thermite grenades. Frag grenades wouldn't do anything to the barrel.

[@scottwatts3879]

My father was a 105mm gun mechanic in WW2 and his battery was overrun, they were out of 105mm ammo, and he was directed to destroy the guns. He first destroyed the gun sights with a sledge hammer and had the pieces thrown into nearby farm ponds. Then he pushed grenades with the pins out and the spoons off down the gun barrels with the cleaning rammer. The grenade would go off and screw up the rifling in the barrel, making the gun wildly inaccurate if the enemy did find some ammo. The rammer would be pushed out and the process repeated. Finally, he removed the breech blocks, beat them up with sledges, including the locking surfaces on the guns, and then had the breech blocks thrown into a mud pit and covered up. The enemy COULD rebuild the guns....but it wasn't going to be fast. IF they had still had ammo, his plan would have been to load one round in the gun, with the fuze set to impact, wedge another shell into the muzzle set to impact, point the whole shebang into the ground, and pull the lanyard with a LONG rope, hoping to petal the gun.

[@allen_steel1236]

I know that the point is to deny the use of the weapon again, however it seems like it's excessively I'm assuming job, you're probably going to be overrun. Most gun replacements for issued thermite packs, there were to be placed on the transversing gear and in the muscle. I know in the case of the self-propelled howitzer. There is usually multiple thermite rounds in a special box, that's designed to be somewhat bullet resistant and Flame proof. And our size specifically to fit the barrel. You're supposed to load the specialized grenade into the barrel close the breach block and pull the cord. This detonates the grenade inside the barrel with a breach closed. It Wells the breech block to the barrel. Or the muzzle I should say and there's no way you can even open the gun. Then if time allows the other gmailing charges that are in the box, look something like a cotton flour sack. They're supposed to be laid on top of the barrel before the Detonator is pulled. These bags the underside will become molten while the top of the bag glows bright red. And she basically calls the barrel to fall off. It's a melting and cutting charge. In training we were taught to deploy both of these and do this in less than 2 minutes. Preferably you did it simultaneously as you didn't want to be near the end of the barrel when the thermite slug was going off at the breach. It's quite a bit of flame smoke and other nastiness would come out. After that we didn't care about hydraulic lines and tires. Occasionally tires would be shot. Or someone wanted to damage their bayonet they would try to stab it through the sidewall. However most military tires are many fly of Steel belts and rubber. You're going to have quite a bit of difficulty and jamming a knife through them. But again the point is disable the weapon by whatever means possible supposedly during World War II one gun crew in the Pacific. Intentionally blocked the barrel of their gun, by slamming another round into the end of the muzzle. And then firing the gun into it. When the two shells met each other. It caused the barrel to peel open like you see in a cartoon.

Sometimes "lead gunners" were issued with barbed "nails" designed for "spiking" the guns. I expect modern guns have some such mechanism designed in form the drawing board.

I read once that in the German Army Field Manual in WWII on infantry anti tank tactics in the absence of proper dedicated anti tank weapons, one rather clever way to at least significantly reduce the effectiveness of a tank in acquiring visual targets was to tie two smoke grenades together by a length of cord or rope or wire or whatever you could find, and toss them like a bolas OVER the barrel of the tank, where they would continue to emit smoke that would disrupt the vision through the optics for the gunner, and potentially through other viewports on the tank as well depending on where the barrel was pointed and which way the wind was blowing.

The wagon that got knocked out by a grenade down the gun barrel was an abandoned vehicle, with a bomb load of ammo, and its MA breach was in the open position. One of our guys did the same to a T-55 by chucking a British L2 frag in to the turret. It did go up, full bomb load. (Op Granby 1991)

[@silverjohn6037]

My vote for the T 72 is it was staged with an abandoned tank using C4 (preplaced on a couple of discarding sabot rounds to sweeten the blast) with a remote detonator of some kind because: 1. The delay between the grenade being thrown and the explosion was only about 3 seconds which is very short for a grenade, 2. Grenades produce fragmentation but little in the way of a fire ball and tanks are specifically designed to survive internal spalling (when a round strikes the armor, doesn't penetrate but causes flakes of metal to scab off the interior hull plate), 3. Throwing a grenade all the way down the length of the barrel at that angle is something a major league baseball player couldn't pull off and this guy barely patted the end of the barrel let alone winding up for a throw, 4. While the secondary jet of flame looks like what you'd get from gunpowder burning off, the initial blast which triggered it was too large for a grenade and too small for a catastrophic failure of stored HE tank rounds.

[@muskokamike127]

[@orlock20]

On older Soviet tanks, the engines are protected by a grill on top of the base of the tank. A grenade placed on top of the grate could destroy the engine and even start a fuel fire. Russia is using such tanks now in Ukraine and Ukrainian drones have been able to destroy Russian tanks by hitting the grill with bomblets. Russians tend to leave their tank hatches open so tanks are getting destroyed from that weakness too.

@@WardenWolf especially for smoothbore guns, which most tanks built today use for a variety of reasons. Given that most shells now are fin stabilized, it's entirely possible that if a grenade went off inside the barrel, the sabot wouldn't even notice, and the dart coming out would be completely unaffected.

Destroying tanks you're incapable of recovering makes perfect sense.

Nice done, as usual. I don't know for the T72 but I know same kind of thing about the french B1bis. French "after action reports" often mention the fact that 37mm anti tank rounds from the Pak36 entered into the barrel of the 75 mm hull gun of the B1bis. The famous B1bis Jeanne d'Arc, received over 150 unpenetrated hits from the pak36 but the 75mm gun has been blocked by a single round. Digression: The high rate of fire of the pak36 hammered the B1bis armor. In addition to destroy everything prominent on the hull (antena, sighting blocks, coupola) this heated the metal to fusion point. The armor broke into hot metalic pieces into the tank, damaging the mecanics and injuring the crew. This have been reported by two different crew from two different divisions who received two different lots of production. (Bernard Lemaire from 4DCr at Abbeville 28 of may, and crew of the 1DCr at Flavion 15 of may) The B1bis has a complex oil system (Naeder) into the drive sprocket. It always spit oil, the B1bis has the flanks covered of oil... The oil takes fire when heated by hundred of pak36 rounds. So, this to say: B1bis is NOT invicible, even face to small unpenetrating pak36

I did a few years as a tanker. . . This all really depends on several factors. Is there a round in the tube? If there is not, is the breach closed? . . Not much else matters. IF there is a round in the tube. . . depending on the round type and how they are made. . On the US Abrams tank, it would most likely result in igniting the rounds propellant and "shooting" the round off. This is actually kind of done on purpose sometimes when rounds get stuck. The type of round the Abrams uses is made out of a plastic paper mache, which OFTEN melts to the tube after firing so many rounds making the tube hot. . . IF for some weird reason the tank crew cannot fire this round off. . . EOD gets called out to "blow it out". . . which is similar to the scenario. .. just goes out the tube and no damage. IF there is no round in the tube AND the breach is closed. . . it will blow, and the shrapnel will go out the tube. . resulting in virtually no damage. IF there is no round in the tube AND the breach is OPEN (rare scenario, but we'll play the game). . it would likely roll into the crew compartment of the turret. In an Abrams, the crew may be able to get out fast enough, but it would blow up and damage some electronics and that maybe some hydraulics and that would be the extent. . . Virtually no chance of reaching the ammo. Now in many of the Soviet designed tanks though. . they have auto loaders and an under floor carousel for the ammo. . . you might pop the turret with a hang grenade when the tanks ammunition also goes off, assuming the grenade hits just right and avoids blast panels. The crew of these tanks would also have a difficult time getting out, because the hatches are smaller (I know this for a fact, I helped Kuwait transition from T-72s to the Abrams and got to "play" with the T-72) I can barely even fit in the turret of the soviet designed tanks and cannot fit in the drivers hatch.

Well Johnny, you forgot about the most obvious problem with tossing a grenade down a tank barrel to destroy it. As a USMC Viet Nam Veteran, I’ve tossed many, many grenades at enemy. Our practice in Viet Nam was to bend the “spoon” back and forth several times to break it off before tossing it a the enemy. By tossing a grenade down a tank tube before doing this, the l “spoon” will not have enough room to fly off and arm the grenade. It’ll be just a grenade sitting in the tank barrel without the cotter pin.

Combat Infantry Vietnam vet here - two tours. After the pin is pulled, the spoon flies off instantly once it is released/the grenade thrown. There is no way the spoon would stay on long enough to make any difference in any situation. Of course, in the real world that person would have been dead long before he got close enough to an active tank to do this. AND, you can't reach the barrel from the ground so you would have to: 1 - avoid all the machine gun bullets from that and other tanks and, 2 - toss the grenade from ground level into an (approximate) 120mm diameter hole. Yeah, right! FWIW In certain combat situations sometimes the spoon was released (intentionally) before throwing the grenade to allow the fuse to burn down for a couple of seconds to reduce the chance of the enemy throwing it back before it detonates. We did this in combat on occasion but it was NEVER a "taught" or recommended practice.

[@KaiSong-vv7wh]

Answer: depends. All tanks use explosive-driven projectiles. Thus, at regular use, there are man-made explosions in the barrel. Now, if the barrel-reloader is automated (usual case), the barrel is always closed. If it is human-driven, it is open when the new projectile is inserted. If you were to toss a grenade into the barrel when it is opened on the inside end, then the grenade would explode inside and kill everyone asap. Otherwise, it will explode in a closed barrel and launch out of the barrel just like a usual projectile.

[@bobblacklodge]

That sounds plausible. If the breech block is closed, only the barrel might get some scratches from the metal shrapnels.

[@LetsPlayBojangles]

The barrel is already meant to deal with high pressure, and a tank round charge is way bigger than a grenades explosive. You could pit and mar the inside of the barrel which could mess with accuracy a bit. To actually kill off the tank, it would have to have it's blast door open so the grenade could go off inside and cook off rounds in the tank. If the blast door is closed you could ruin the barrel if you managed to detonate a round that's primed, the barrel is meant to deal with the powder charge, not the detonation of 4KG of explosives inside of it. The blast door would save the tank as it's literally there to save the crew from a round misfiring and exploding in the barrel but it would render the tank combat ineffective.

[@inductivegrunt94]

The risk is great and the payoff is not worth it. So it'd be best to open the top hatch and dropping it in rather than down the barrel is a much better way to do it. Another great debunking video on Hollywood vs reality. And another great use of Girls und Panzer, I really liked that part.

That T72 footage almost certainly shows the stored ammo in the turret being detonated with the hatch open. It could have been initiated with a grenade but more likely an improvised device or charge of some sort. Since this tank has no blowout panels the visible eruption of flame is just the explosion sending propellant and hot gasses out through the open hatch(es). If they were closed at the time the turret could very well separate from the hull, an event known as a "turret pop" which was observed in the early days of the Middle East conflict, notably during the Battle of 73 Easting in 1991 and "Thunder Run" in 2003.

Thermite is fairly easy enough to mix up but normally not ignited with a grenade unless it was a not a frag grenade in the first place. I don't think there was much of any rounds as far as explosives are concerned. Could have used up its rounds before being abandoned or they were taken for other uses. Tossing in a flare or thermite grenade into the top would be hard and you seen how big the tank was so someone dropping it in and running off would be dead or very heavily injured.

American tanks are usually scanning for target of opportunity so they would always be moving. That being said, I did see a tank fire with a muzzle boresight device still in the end of the gun tube and it did split back like a banana peel. another time a guy drove the gun tube into a tree and plugged it with 8 inches of wood. They shot and cleared the barrel, no problem. In Desert Storm, we took a nose dive into a anti-tank ditch and the gun tube plugged up with about 3-4 feet of sand, which we expelled by firing the cannon with a sabot round in the tube. No damage to the gun. I've also shot many items stuffed on the end of a round, just for the fun of it and everything shot down the barrel just fine. Those gun tubes can take a lot of abuse.

Thermite will result in a lump of iron fused to the inner barrel

[@edi9892]

@@AdrienLegendre However, it will take time. If you fire the cannon within 1s, it will probably eject everything.

[@alanrobinson2901]

In 'Band of Brothers', they used dynamite set off by German stick grenades to blow the barrels, they knew a grenade alone wouldn't do the job. I doubt any standard anti personnel grenade would produce pressures capable of destroying a barrel.

[@DustinDonald-cz9ot]

Nah the pressure from the shell alone is far more than any antipersonnel grenade could do would be like throwing a firecracker down a metal pipe won't do nothing.

[@alanrobinson2901]

@@DustinDonald-cz9ot Yes, and no. IF an American frag grenade went off in the barrel, it MAY obstruct the barrel with enough fragments that firing a round COULD case jamming of the fragments in the barrel bands and therefore increase barrel pressures and cause a massive over pressure of the chamber. NO good gun crew would fire with that possibility. Barrel obstruction is a major concern.

Just ask Vulcan Raven back at Shadow Moses..

[@thephilpott2194]

I reckon the Syria footage is most likely of a disabled tank that has been abandoned. The opposition most likely got inside, opened the breech, then popped in a grenade from a position of relative safety outside. Praising god afterwards was superfluous, then again they're probably just the local rabble making a PR video rather than soldiers taking strategic or tactical action.

[@igorgiuseppe1862]

5:00 there was no one helping protect the tank so it might be fake

[@user60521123]

I think you’re completely correct. I don’t see how a grenade can obstruct the bore if just rolls or slides down. I think the most of the shrapnel, debris and blast will just shoot out the muzzle. Although the shrapnel and blast would probably do damage to the bore. Even bore obstructions aren’t always catastrophic. Anyway, really interesting topic. As for the Syrian footage, if the breach is designed to handle a tank round how could a grenade, which releases much less energy even damage the inside of the turret? The footage looks like the magazine exploded instantly, which rockets don’t usually do-it’s more than likely fake.

[@Gracefulwarrior2124]

If the breach was opened, the grenade would literally land in the middle of the carousel of ammunition. This would be able to damage ammunition. Of course I thought a T-72 and later had an autoloader which automatically works the breach, so what am I to know

[@JoFa876]

A breech that is open, could allow the grenade to enter the tank, and possibly set off secondary explosions. It is probably unlikely in most cases and the Syrian incident could well have been just a whole lotta luck.

[@user60521123]

@@JoFa876 Okay, I didn’t even think about the breach being open, but they would have to drop the germane just as the crew is starting to load the main gun, since I’m sure it’s usually closed. I know in WWII, the Soviets destroyed Tiger tanks by throwing Molotovs into the engine compartment-why not throws a germane there? Less risky than running in front of a tank.

[@MichaelLlaneza]

You hear machine gun fire after the first grenade, there's someone in there.

[@n00bist723]

​@@MichaelLlaneza You mean the machine gun fire coming from behind the camera? The machine gun fire that a matching sound profile of can also be heard mixed in with other celebratory shots after the tank is on fire? Also the "it fired a shot after the first grenade failed" proof that it's not staged falls flat too that "shot" "happens" when the insurgent is directly under the barrel that's some serious concussive force potentially fatal but he doesn't flinch, cover his ears, have his clothes move and no dust is kicked up/no muzzle flash. Top of all that you can hear the audio slightly cut and a quick fade out of an "aloha akbar" a split second before the tank "shoots" as well as what sounds almost like the trailing end of the same muzzle retort cut in abruptly as if the start of the audio clip the editor used got cut too early while recording back to back shots from another clip(note as well the video doesn't skip or have any oddities at this point so this is only the audio track). I did 2 years of video classes in HS and still regularly edit shit on my free time and was/am good with granular audio editing stuff, this is clearly as day sloppy audio edit to me. I am extremely certain this was a demolition of an abandoned un-crewed T-72 where the first attempt to cause a ammo cook off failed and the second succeeded and was staged to look like a hero insurgent killed this tank in active combat as a propaganda piece.

[@alexrockey3730]

Here is something I've been wondering for a while: what if some form of high-explosive round is loaded and someone managed to fire a bullet down the barrel? Could it be able to set it off?

[@PrebleStreetRecords]

No, the detonator of an HE round is only enabled after the round spins a bunch of times. Same with 40mm ammo.

[@broadsidestorm]

I certainly didn’t expect a clip from Girls Und Panzer here. Very nice

[@drazenbicanic3590]

The t 72 series has an automatic loader, in wars it has been shown that a hit that would not normally destroy a tank can cause an explosion of ammunition in the loader. a grenade inserted into the barrel can cause a similar effect, especially if the breech is open.

[@mansourbellahel-hajj5378]

Another great video you know in band of brothers during brecourt manor they blew the guns using German grenades and rendered the gun useless so it is a possibility to apply it to the tank however the tank is higher in height for that to happen it requires someone who is definitely careless about his life to do that or he has no choice what so ever.

[@AC4ace]

At Brecourt Manor the grenades weren't directly responsible, they were used to detonate blocks of TNT that had already been shoved down the barrels.

[@rusty9097]

for the whole ammo blowing up thing, most modern tanks have blast doors that seperate the ammo compartment from the crew meaning the grenade would only strike the crew and/or the breech, barrel, though if the door was left open maybe a very slight chance it hits a round but if the crews fine they possibly could close the door quickly and let the blowout panels (if the tank has any just using modern abrams as an example) do the work before exiting

[@HoztileMANIkyn]

good thing that grenade was nice enough to patiently wait for that guy to climb out

[@AndrewTranBaseball]

Still surprised of how small the fighting compartment in the Leopard 2 is.

[@bobcohoon9615]

One of the first King Tiger tanks in WWII was destroyed by a small 2" hand carried mortar. The mortar put a round right on top of the engine covers and started a bad fire in engine compartment. The tank slowly became an inferno
