Greystone was a name change for BlackStone, I think it was called. Remember they were in Iraq and the liberals had kissy fits about that.
Blackwater. A bunch of Scott Coleman type characters.
You were referring to Blackwater, and their new name sounds like a cologne, XE. One of my college fratmates worked for Blackwater previously. Tells me if you’re an adrenaline junkie, this is the job and they damn well know how to shut up.
