A terran Ration can provide half a day's nutrients... Calories, Vitamins, Carbs, you name it... in one bar, and one canteen.

It tastes, quite ironically, like licking a rat, but for nutrients and survival, it can't be beat for its size.

I don't know what Caelondian rations are like. Probably not nearly as advanced as what I'm used to, but still... Military rations are made to pack as much punch into as small a package as possible. If we can find a stockpile of them, we can feed just about anyone for a month or more.

... They won't be happy, but they'll be alive.
