The details waiting fpr class.
The smoke grenade stories remind me of one. IIRC the old NCO academy at Ft. Bragg had a night defensive position problem. It may have been someone else but we were assigned to probe the positions. I noticed a machine gun position. When the gun fired I couldn't see any muzzle flash so I determined that it was improperly placed behind the military crest. Note: I don't think I would do this with real live pop-up shoot back targets with live ammo. Determining that I could safely crawl to within grenade range of the gun I did so and launched a smoke grenade in the direction of the gun. Dayem!! I hit one of the crew right in the chest with the grenade and singed and scared the shit out of the crew!!. I stealthily withdrew just in case some one in authority didn't think it was the proper thing to do.
