Well, I'm not too much in favor of the Air Force since we haven't won a war since the got away from being the Army Air Force. They were much better when they were, "Down we dive, spouting our flames from under" than, "We took the blue from the skies and a pretty girls eyes".
The Army is just a bunch of ground pounders and why march when you don't have to? The Navy provide free transportation. As far as Marines go, they're the guys who were'nt smart enough make it the Navy.
For those reasons, I go NAVY - all the way!
