 grenade play I was really hoping for one of these idiots to drop one. |
All the neat things you (sorta) learn in SGT's time.  Of course, there wasn't any info, even a SWAG, as to how much delay you'd have per layer of duct tape. ETA we were taught this in case we had to abandon our MI vehicles during battle-I imagine it'd be even more effective if you could get the prepped grenade into a fuel tank. |

Grenade in the middle of JP8? Probably wouldn't do too much. Why? No igniton source since the fuel surrounds the explosive. And the dispersal of the fuel would absorb much of the energy. Foogas uses explosive on one side of the flammable liquid, forcing a cloud of vapor and having one side of the cloud open to the explosive blast where it can ignite. Fuel vapors have an upper and lower limit on flammability. Too much fuel and not enough air and it will not burn. To little fuel is self describing. Fuels like jet fuels, diesel and gasloine typically have limits at 3-12% for flammability. Fuels like acetylene and ethylene oxide are much higher, 2-90% As far as the original video, those two idiots are begging to frag themselves. Just how they got on the battlefield where they found grenades. |

I used to work for a retired AF Colonel who flew C130s in Vietnam. He told me that they would put frag grenades in glass jars and pull the pin. As long as the jar wasn't broken it would hold the spoon so that the grenade wouldn't explode. They would put a few of them in a box and shove it out the back onto enemy positions. He didn't know if they ever killed anyone by doing this, or if it even worked but he said it made them feel better just fighting back with something. Luckily they never had any accidents with them while they were still inside the aircraft. I didn't have any problem telling him how crazy the whole thing sounded to me, but he said "you had to have been there to see why we did it". |

Peter: Carter, hand me my thinking grenades! Crater: (Hands Peter grenades) Peter where did you get these? Peter: Shhh! Carter, I'm thinking! (Throws grenade out window and it explodes.) Peter: Uh huh. (Throws a second grenade and it explodes.) Man: (outside) Oh my God! He's dead! Peter: (oblivious to his actions) That might work. (Throws another grenade and it explodes.) Man: (outside) What's happening? Peter: I've got it! (edit) |

Who are you guys kidding? You just wish you got to play with live grenades with a nice big happy BMP to take refuge behind while you did it, too. Hollywood never gets grenade play right. Other than "Heartbreak Ridge", I've never seen a movie that includes the sound of the initiator popping after the spoon flies away. CJ |
I doubt it. Did you see how the camera caught several exploding on the ground? That is risky. But you are correct about the M67 filling. But those might also be picric acid that had been exposed to water. It really gets weak but it also can become sensitive when in contact with metal. I doubt any EOD would touch such junk. |
| Germans in WW1(and, likely british and Americans as well) caused much havoc and death by removing the standard fuses and placing short(immediate) fuses on grenades to be captured by the enemy. These soldiers should be more careful, assuming that those are captured munitions. |

I've heard rumors of fuses that had reversed timing numbers on them. The number that indicated a 5 second fuse (5, I think it was, which was logical) actually was a zero delay fuse intended for booby traps. It'd blow up the moment you tossed it. I think the Russians did exactly that to some captured German grenades, which later found their way back into the German supply lines. If I have my story correct. CJ |

I have seen stupid stuff from my own guys I hope they are not. I am pretty sure the eastern bloc countries didn't mess with picric acid. The only ordnance that I know of that you have to worry about picric with is Japanese. Japan was the only ones who used it in large quantities some old U.S. tank rounds contained Yellow D that was a derivative of picric but it gest less sensitive or time. The URZGM fuse can be used as a booby trap by pulling the spoon lever away from the body because the tip is just a fork holding a firing pin away from the primer. They also come with time delays between instantaneous and 20 seconds for the sole purpose of booby trapping, They're labled but the numbers don't correspond with the time. |
I agree with my EOD brother, the Japanese were biggest users of Picric acid based explosives and all Japanese WWII munitions should be treated as containing Picric acid based explosives till positively ID'd. The US used Ammonium Picrate otherwise known as Explosive D in Armor-Piercing bombs and Armor-Piercing projectiles during WWII. I blew up several AT projectiles at Ft Irwin. The RGD-5 has 110g of TNT filler and the F-1 has 60g of TNT filler. |
