Take a look at some of the rations from other countries. Somewhere in there I remember it saying the going trade rate for French rations was 5 to 1 (5 MREs = 1 French) since they are very good quality. I think that was on some peacekeeping mission or other.
Check out the Russian rations. "I would not eat the ration again. The taste and quality were not good." I thought it was just exaggeration that they were bad!
I had some British 24 hour ones too. Some good stuff in there, but holy moses talk about sugar! Their sugar package is probably 3 times the size of our sugar packages (you know, the paper ones you get in restaurants). Plus, even if you added one triple-size sugar to EVERYTHING that could possibly take sugar, you'd STILL have some left over!
Even the desserts are really sweet. The treacle pudding was not bad but I had to stop eating cause my teeth were starting to hurt it was so sweet....
