First Strike Rations.
http://www.youtube.com/watch?v=76ba-uQCVuUWeird, First Strike Rations are meant to be high density energy rations. In the video, you can spot Fat Free Mayonnaise

.
Apparently Kraft make a Fat Free Mayonnaise Dressing for fat people. Could it be the same stuff?
Where are the pringles and Slimfast milk shakes when you need them.
BTW what ever happened to the ration the folks from Natick developed, that you could urinate on to rehydrate. Must of been a salty affair.
