I have a rather different intepretation to offer:-

1) First of all, it seems that the sergeant is telling them that they should eat it in 7 days' time, not immediately, and that they should only cook it once after that 7 day period. The 7 days makes a lot of sense actually, as farmers routinely "hang" their meats in chilled environments for up to 3 or 4 weeks so that the bacteria and enzymes can get to work and predigest the meats, making them softer and easier to absorb. Leaving it out for 7 days in a hot environment would speed up that process, turning it into rotting meat, which incidentally many hunter-gatherers eat in quantity in raw form(Inuit and muktuk etc. etc.).  Plus, many rawists have eaten rotting meat that has been left outside for 7 days or even more, without issues, so the notion that aged, raw meats are so dangerous is rather unlikely.

Anyway, one of the main tenets of rawism is that, if one has to eat cooked foods, that reheating foods which have already been cooked  is even worse. Not only do the amounts of heat-created toxins rise in the twice-cooked food as a result, but the idea is that bacteria are only really unhealthy within a toxic environment such as cooked foods or grainfed meats and the like.

"The Sergeant says, "don't laugh, in 7 days you'll be eating 
that". Aghast the recruits go and do warfare training. A week later, the 
baboon is hauled down. "OK lads, if you are stranded and starving, you 
might have the good fortune to come across a nice fresh carcass like this".
 
The baboon is cut up and cooked (not sure if boiled or roasted). The 
recruits all eat it up. It does not taste good.
 
"Lads, you can eat the animal once, but you must NEVER try to reheat 
some of it later on". Once is all you can eat it. Try it again, and you 
might die"."
