I read a few that make me think "what the hell was he thinking?!" But then there are others that are accidental. Like there was one where an officer decided to fake a knife attack on one of his soldiers to train his squad on deflecting the attack. He surprised his soldier, who, in the heat of the moment reacted instinctively and shot the officer. IMHO I don't think that an accident like this belongs in the same categorized list as others like where a man tried to weld a live grenade to a chain.
With the rocket one, I think the 10 meters is an exaggeration, but it is quite possible that the man was thrown a little bit and then staggered further away before he released his last breath. My question is who was at the detonator that allowed the rocket to hit this man.
