I don't think they're military, but I've been eating SOS Labs (?) survival rations all day.  Gonna see if I can eat the stuff straight for another day before I stock up some more.  Canned food is just too bulky and since I move a lot, it's a pain logistically.  If I have to go 30 days on my supply, I'm sure I won't be complaining so long as I have something to eat.
