Food Story:
The "Frank's original red hot" was a southern thing from the guys from the Carolina's and Georgia. Tabasco was from the Louisiana/East Texas guys while I was at Ft Polk, LA in '68.
Never had any of the WW2 K-rats in Viet Nam, but had lots of C-rats from Korea, 1954/1955. Guys from the southwest would have Tapidero shipping in, Yankees Tabasco and Mid-westerner A-1 sauce. I was there during the "Sargent Majors" period where the top enlisted men in country were selling our food on the black market (and to officers' clubs) and feeding us (Army) rice and surplus food from the Philippines. Ended up with over 20 E-8's and E-9's going to Leavenworth prison.
Our unit was next to a LRRP unit and we would raid they for the early freeze dried rations to take on missions. Actually it was very good with water and heated with C4. Problem was it didn't have any fats, so with we share "Ham and Lima beans" to keep going for another day.
