As I have a bottle of snake sitting next to me at the moment, I am inclined to disagree eith you on this one.
I belive bottles of water handeled by infadels, and a steady diet of menu 22 from the MRE warehouse would be better.
FYI, Menu 22 (the ham and shrimp jambalaya) is the absolute worst of any MRE menu, completely inedible. There are tons of them laying around, as no one want to eat the damn thing.
Civilian reaction to one:
