There are many interesting and special-purpose rations detailed in the document released by US DOD yearly : a copy which can be found here
http://everyspec.com/ARMY/ARMY-General/ ... 012_49978/ or just google natick pam 30-25 , such as the entire UGR family, MArCs, MREs for religious purpose and Tube foods etc
Why have none of these rations managed to "fall off the truck" or somehow or other manage to get into the hands of civilians ? And if they have, why haven't they made any reviews to share with the ration community?
I have yet to see a review of an UGR of any sort or a review of U2 pilot's tube food
