Notes: Some Alien autopsies said to have been performed at 29 Palms.

I'm not familiar with most of these places, but the company I was assigned to, had to go through training there.
As far as I could tell, it was just an infantry team integration and training center and maybe a test sight for new infantry, mobile/mech infantry
weapons.
I've never seen or heard anything about aliens there.
