Speaking of grenades, this reminds me of a book I read about some 101st Airborne LRRPs in 'Nam.
They were patrolling and came across a VC body that had been booby-trapped. Thinking they'd turn the tables on the Cong, they took a smoke grenade fuse (no delay) and screwed it into a standard frag grenade. Then they pulled the pin and wedged it under the body with the spoon held down.
Well, it turns out they got recalled a few hours later because a line unit was going to sweep the area. Not wanting to leave their booby trap and the Cong booby trap to hurt American soldiers, they went back to set off the booby traps. So they figure the best way to do it is to tie a rope around the body's arm, get back, and pull the rope so the body slides off the booby traps and sets them off. So they tie it off, and one guy gets back as far as the rope will allow. So then the guy
YANKS the rope as hard as he can and ends up falling on his ass...... because the body had been rotting out in the jungle for about a week and the guy ended up pulling the arm OFF!
