Major Hackett (*Spoiler*)
So what was Major Hacketts deal, cause when Sgt. McRose catches him in the act of betraying the team and stealing the accounting Documents he asks him how much he was in for and Hackett says something like $10million bucks. So was he stealing the documents to cover his own arse so nobody would know he had any dealings with Cash, or were the documents actually worth money to external buyers hence why he was stealing them?
