Hey I even liked the coffee they made an Army bivouac that you ladled out from a huge pot. A Chaldean friend once made Turkish coffee for me and it tastes exactly like the Army coffee.
C-rations coffee powder in a canteen cup, heated on the vehicle heater vent on the floor along the front of the track,assuming your heater worked,lol.
Nothing like the tang of diesel with your coffee to wake up to!
