Yeah, correct me if I'm wrong, but wouldn't most ex-military astronauts come from the Air Force? They might be good physical specimens, but I don't think they'd get extensive survival and hand-to-hand training.
Not all of us. I happen to be an exception.
But for the record.....in order to become a pilot in any branch of the military you must be an officer. And to become an officer you must have a college degree. In the appropriate fields mind you.
And once you become a pilot--there's a basic hand-to-hand combat course you take (a watered down version of NavySEAL combat which is a mix of krav maga and aikido).
Just throwing that out there. So the astronauts will be able to take care of themselves. So you got brains plus a mean chokehold.
Astronauts still win.
