... without stripping one from a body?

Hi guys. I've checked the wiki and it only lists two locations both of which are on dead bodies. I don't want to do that from a role playing point of view. So I guess I'm out of luck but I thought I'd ask anyway. I've just been aboard the Prydwyn and I though there must be one laying around, or I'd be issues one or I could buy one from the quartermaster but oddly no. Do they become available later on?

I do have field scribe fatigues I bought from Scribe but I want one of the groovy brown ones.

Cheers guys.

I think the first time I got one was after the battle at the police station and there was a dead body lying around. It wasn't there in another play through, but there are always more than enough Vertibird crashes to loot from.

He did say without stripping one from a body, you know?
