AMC pool pilots   

To walk into a base with a crew you don't know and they don't you.  If you have good EMS experiance, it's easier to do.  But if you are right off the street and trying to do this job, without making a bunch of people mad, good luck.

Also, isn't it funny that if you get assigned to the base you have this long, drawn out orientation requirement.  But if you're filling it, they basically throw you the keys and say good luck.
