Bold words are key. Join the service you want, then, for the service, not the aircraft. I know guys in ROTC that switched to Marines because they thought it would give them a better chance to get jets (since lots of Marines want helos). Guess what they got... wasn't jets.I'll be happy flying anything, but I want to be in a fighter or attack class of jet or helo and the Marines seem to be the way to go for that.
Marines also have the JSF coming so going Marines wouldn't keep me from my true dream.
Anyway, if you really want the fighter/attack aspect, you'd probably have a better chance in the Marine Corps. But keep in mind all the other aspects of being a Marine and what they involve ..
