IN 1968 I was in Viet Nam, my unit was detached from the main unit. We ate a lot of C-rations. Ate all of them, like most units the eggs and ham, ham and lima beans got tossed in another box. When things got tight and chow was scares they got eaten. The best way I found to heat a meal was water in your helmet and heated with a chunk of c-4. The pecan coffee cake was pretty good heated. We took 4-5 pack of the instant coffee and boil up a gallon of water, it was drinkable. We got a couple of Viet Namees rations dehydrated rice, shrimp and veggies. Hot bad, but go real easy on the red pepper flakes cause you are going to feel them again.
State side I work a strange night shift, my guys and I would get meals from the in flight kitchen. lots of good fried chicken and bag lunches. Sure could go for some SOS with two over easy eggs and some hot sauce, cold milk and black chow hall coffee. That a meal to get you through a long night of pushing pallets and unloading aircraft.
Spam... No Spam ever again ate to much to often; there is no way to prepare spam that I have not eaten it. I can't stand the smell.
Care package form home while in Viet Nam included Vienna sausages, smoke sardines, tuna fish, hot sauce, those little glass jars of cheese. gouda cheese, crackers and a small canned ham. gum and Kool Aid. pop corn was used as packing but that got eaten first.
