I saw em making coffee in my early days on KP. Take a 30gal pot boil water and pour a couple pounds of no name coffee grind in, bring to rolling boil, turn off heat, ladle out what's above the crap on the bottom. Never had a drop til I was a PSG punching Infantry studs still at fourty years old. Prolly pretty similar to Gordie Howe playing hockey at 50yrs. Yer body is broke up from one to many bad parachute landings and being mortored a few to many times.
Smokin just dumb, good way to get round thru yer knot and the boogers can smell you in bush 50yds away.
