Navy, all the way. We don't "butt rape" each other in the Navy, by the by... we just beat the shit out of each other and make a bunch of gay jokes. We like to get drunk, too, but that's more of an all-around military thing, not just Navy.
Seriously, tho, the Navy's a sweet deal. The Army ain't bad, tho- the Army and Marine Corps are the ones who go on the battlefield and shoot at the bad guys; we just get 'em there, provide support during their stay, and pick 'em up when it's time to go home. So we're not really the 'heroes' of any war by the traditional sense (but tell me how the fuck they'd survive over there without our support).
