Have you ever been present when a weapon was accidentally discharged?

At BCT during our first ftx. We were sitting on the ground listening to our first sgt. A guy thought he had his weapon on safe... It was on burst and he it fired off. It was a good lesson for all of us about being aware of our weapons. Yes life sucked for him the rest of the day.

Active duty exercise, a guy Kuwaiti soldier shot the exhaust port of my m113 with m60. I was in drivers seat and ducked inside as rounds whizzed past. One round went down in my fan tower and you would hear it rattle around sometimes.

I was infantry on active duty. The 1st annual training I went to for guards was artillery. The colonel took me to a firing battery to watch them shoot. He said,"if you look down the tube here. You will see the round leave." He walked over to the TOC. The 1st volley went off the howitzer blasted threw the trees and branches flew everywhere. A "plate" came off the back of the round and rattled in the trees. Someone came out of the TOC and yelled "CEASEFIRE" everyone exited the guns and we were waiting for range control. So I decided to see if I could find that "plate". I never did. When I walked back. People were getting chewed out. I had thought to myself,"wouldn't shooting that low change the path of the round? Maybe at that velocity it doesn't matter." I didn't ask anyone because it was pretty bad situation. Later back at battalion TOC I asked the colonel and he said,"you saw the misfire?" I have infantry background that was 1st time I'd seen one fire. It was a miracle I was there. Turned out to be a bad round not crew error. The round landed in the Mississippi River. Some people were fishing nearby. Luckily no one was hurt.

Yes, we had a couple of ND's (both involving blanks) in OSUT. One was into the ground at the CTA (all ammunition should have been long gone at that point), and one was inches from a soldier's face on our FTX. We had a full memorial service for him (as if he had actually died) and the offending soldier had to write good letters to all of his family explaining how he had killed their loved one.

USS Mahan DLG-11, off the P.I. in the missile test range, 1968. I was assistant ship's photographer. Got permission to observe and photograph a missile launch. the missiles usually shot off the rail like a bat out of h%ll. This time it dip like a plane coming off a carrier, went out about two mile and the second stage started while still attached to the first stage. Two of the bolts holding the stages together blow off. Now the first and second stages are running full blast at a 45 degree angle from the intended flight path. Fire Control blew it up. Forgot all about the photos. I wanted to watch but wasn't sure if I should.
Turns out the telemetry was warmed up on the launcher rail without a missile.

Yup ... BCT

If you clear your weapon with a loaded mag in you are an idiot. Now you if you pull the trigger because you like the feel of it and you don't know where your muzzle you are going to hurt yourself or someone else.

I have seen misfires, but never accidental discharges.
