C-rats are what we ate in basic and then at my first duty station when we went to the field. I am pretty sure I still have my P-38 on my dog tag chain. Then came the MRE's. The dried hamburger patty and dried potatoes were a little hard to get used to. Dried fruit was good. Did like them when heated ala Thailand sun but didn't heat up very well in Korea during the winter.
C-rats were ok. Tried the can in the helicopter turbine exhaust trick (after it was shut down, didn't need a can to go flying into a tail rotor) and worked well. Some strange combos and lots of tabasco made them edible.
