Stitchblades, honest question, what the hell is CPO, Chief Petty Officer? 

Most men I've ever talked to if they are going to talk about a man who is in command of the they will only say C.O (Commanding Officer) never once have I heard them do an abbreviation of rank, the only time a rank is abbreviated is in writing. 

Not nit-picking, (Ok well I am, not intentionally rant just came out, maybe a little cause its 12:30 A.M and I haven't slept since like 6 AM yesterday.) but its just something I'm checking out, and probably at the moment sounding an ass about....
