My Army Aviation unit still ships pilots out to SERE school, although there are three levels of course, SERE 1 which is an online course, SERE 2 which is a 1 day course with only a little hands on training, and SERE 3 which is mandatory for pilots, 1 week spent implementing everything you've learned in a simulated training environment.

Supposedly they give you a rabbit, and you have to keep it like a pet for a few days, then they instruct you to kill and eat it. Shock value I guess. I've also heard they're allowed to break small bones in your hands and such during the "interrogations"
