a military repo ration outfit sells these in a Altoids
style box with some sort of WW2 label..and a refill tube
comes with it..they say something like "survival tabs..as
in keeps you alive but expect to be hungry" or something
like that..i would think if you were in a life raft or
not active in some sort of shelter..basement..cave..??
and had nothing else these would keep you from not
starving as fast as nothing at all..
]Yeah. Thats what got me on this search for some sort of compact ration that is shelf stable at car trunk temperatures (80-100deg)for use in a car BOB or as a light weight backup to regular food while backpacking. That was the WW2 concept behind the emergency rations. A ration that I really liked is the U.S. Military Food Packet Survival General Purpose- Improved. It has good variety. 6 bars. 2 Shortbread bar. 1 Granola bar. 1 cornflake cereal bar. 1 Chocolate chip desert bar. And 1 Wintergreen bar. The Wintergreen bar a 1"x3"x1/2" certs like breath mint. That was the hardest to eat but very refreshing. It also comes with a packet of ice tea and a bouillon packet. Rated at 1147cal total for 5 days. I ate the whole thing in one day. I think the variety made me
feel better. They are hard to find. My local gunshow sometimes has 2004 dated ones for $5. Shelf life is 5 years @ 80 deg. They can also be found here:
Life Support International but I've never bought from these guys.
