How does a grenade launcher work? - All about grenades Part 2

(7min mark) the way the 40mm has a safety mechanism with the bearing acting as a detonator block is the coolest thing ever. Whoever invented that is a pretty smart guy.

My buddy who was in Vietnam loved his M-79 "Blooper." Once, though, when he had it resting on his hip, he accidentally fired a round straight up. All the guys were looking up to see where it would land. Luckily, it landed at a safe distance. We miss you, Robert. ("Bobbie" R., 4th Inf. Div., 1967-69, around Pleiku, Dak To, etc., two tours) -Old Guy

[@ThatSockmonkey]

I was in the Australian army in the 90s and I've heard people call them the blooper, pooper, poop gun, poonka, and supershotty! I love the sound, and with practise, you can get pretty good accuracy. One kid on a recruit training course I was working landed a grenade right into his platoon commanders bush hat at 100m. (Aussie tradition, the COs bush hat get put on the range during grenade training. Usually results in a few frag holes and some laughs, it's good for unit cohesion and morale) I've fired many, many smoke and illum rounds from these on exercise, and a couple of grenade variants on the range. Probably the most fun range day of all the weapons I ever worked with. Excuse me, I gotta go listen to Bruce Springsteens Glory Days and talk myself down. "I'm not 22, I'm not 22, I'm not 22...."

[@fratercontenduntocculta8161]

Grenade launchers are my favorite support weapons. Something about the arc trajectory of the projectile makes sense to me, and even at extended ranges, I have no problems getting a shot in thru a window or door. If you really think about it, the magic is in the ammo itself.

[@samuelclayton4405]

I am an Infantrymen. I carried a m-203. Perfect Weapon for several different applications. Anti-Personal/ Anti-Material. Several different type of round were used. There was a HE, AP ( would go thru a door or a hood of a 6×6) Lightly skinned Vehicle, and APers (Anti Personal).There was a Shot round. It was like a shotgun shell full of .30 Caliber shot, and then there was the Flechette round. It kicked like an 8 Guage shotgun.

[@ralphgreenjr.2466]

The old M-79, "Thumper", was an ambush buster. A good gunner could have a half dozen rounds on the way before the first one hit. The shot round and flechette round was devastating up close. The gunner also carried a 1911a1, .45 acp. Gun of my youth.

[@Brodrich]

Not sure when it came about but the "defence" problem mentioned at the end of the video forgot to mention that they made 40mm buckshot rounds. It basically makes a grenade launcher into a blunderbuss. And while I already knew about it this explains to everyone why EA made it so the grenade launchers in battlefield don't go off when you shoot an enemy with it at point blank range.

[@aperson336]

The buckshot and flachet rounds were terrible in the m79 due to the m79 using low pressure chemical explosive rounds, whereas flachet/ buckshot are high pressure This causes the range to be terrible as well as velocity and spread

[@Brodrich]

@@aperson336 Explains why they are so terrible in Arma 3. Thank you.

[@paulredinger5830]

I used a M203 when I was in the army in 1982. Beautiful weapon. Kinda weighty especially carrying the grenade and the M16 rounds though.

[@VictorW23]

The centrifugal fuse to arm the explosive in the 40mm was genius

[@pretzelogic2689]

So when our company got to pull Green Line duty for 2 or 3 days on a remote LZ, we would play a little game with these on guard at night. You put one in the tube and 2 on the sand bags in front of you. Fire the first at a high angle, reload the 2nd and fire medium angle, and the last at low angle. The winner was the one who got all three rounds to impact at the same time. It was called H&I, harass and interdict, so it was "officially" approved.

[@mechadonia]

Thank you for the explanation of High-Low! I remember reading about it when I was in middle school and just never being able to visualize how it actually looked inside a 40mm casing or how it actually worked. Still never really grasped it until now.

[@upandaljm]

The tough part is keeping the thing on target while you're laughing your ass off because you know what's coming.

[@jamesdoesitmatter]

Thank you for covering the high-low. Most have no idea it's not like a bullet. Close but not the same.

[@thewheezychieftain5488]

Actually the Russian RPG is a 40mm grenade, since the inside of the tube is 40mms, whereas many widely different warheads that sit outside of the barrel can range from 40mm Anti-personnel shrapnel rounds or 90mm enlarged armor penetrating warheads.

[@anthonyc417]

[@dabprod]

In 1964 I was stationed at Ft Benning GA and assigned to the US Infantry Board. I tested small arms weapons and the M-79 was one of them. We had our own ranges because everything was classified and all personal held top secret clearance. The M-79 was my favorite of all. We worked on modifications to the weapon.

[@bob_the_bomb4508]

Great explanation and excellent graphics :)

[@thebookwasbetter3650]

Knew a Vietnam vet who had a cool story. He said a guy in his platoon shot a tiger with a blooper (grenade launcher) He said the thing was running at him and he shot it. The reason it didn't explode is because it was very close and the safety mechanism worked with centrifical force. The round has to spin something like 40 times before the centrifical force disengages the safety. So the round didn't detonate and pretty much acted like a big shotgun slug. The guy had a picture of his platoon posing with the tiger with a four inch gash in it's side and he wore one of it's claws around his neck. Sorry if you like tigers, but I thought it was a pretty cool 'hunting' story.

What you didn't mention is that high-low propulsion system was developed by Germany in ww2 for anti-tank guns (the PAW 600 and PAW 1000)

[@KalanYore]

You missed one detail of the 40mm being armed as it takes 3 revolutions after firing within the launcher tube of the M-79... there is a reason for this so when a solider accidentally drops the munition will not explode to cause death or injury... the max range is 400m beside the fragmentation grenade there is other types like white phosphorous and smoke... In the army we trained with M-79s, just for familiarization while the actual M16A1-M203 attached grenade launchers for training using training markers rather than real frags - the targeting aperture is actually called the 'Leaf-Sight'... I was at Ft. Dix back in 1987 for boot camp - the only live munitions we used was 5.56 NATO, .50 cal BMG, 7.62, and live hand grenades... everything else was non-live training munitions or simulators... claymore mines we used real detonators [wired blasting caps] for training but the mine itself was a dummy... still wired blasting caps were dangerous can remove some fingers or even the entire hand from 'static' energy - have to be well grounded when using wired caps... training grenades used live fuse detonators as well - I and a few others were assigned to screw in all fuses and also load all 20 & 30 round magazines with fresh ammo including tracers when we had night fire exercises. Spent 8 years in the army... got out as the Clinton Administration was destroying and reducing the entire military and cut programs and pay to freezing promotion slots to slow and reduce E-5 & E-6 slots and NCO school intake - I had enough of the BS and ETS out.

They felt that the enemy knew about the discovery and would try to recapture the weapon’s .

[@jeffyoung60]

The Imperial Japanese Army from 1932 to 1945 developed and employed the effective intermediate distance Type 10 and later Type 89 grenade 'discharger'. It is surprising no other army adopted this effective weapon. It would not be until the Vietnam War that the U.S. Army deployed its own M79 grenade launcher, which proved successful and popular. Post-Vietnam, the U.S. Army went one better. It withdrew all M79 grenade launchers and replaced it with the M203 system, a combination M16 with a modified M79 mounted beneath. The M203 proved effective, successful, and popular.

[@Stirl2]

It's not "millimeters", just "millimeter" in this instance.
