What is the most intelligent branch in the armed forces?

Holy loaded question, Batman! :)

None! People are smart not the branches of service. But if I had to chose a branch I'd say the AirForce because they broke off from the Army and said: the hell with going to the field; the hell with organized PT; and the hell with dealing with those smartass Warrant Officers. Well I don't know if this makes them smarter but it definitely makes them different than the others. Just a little humor y'all!

Going purely by medical ratings, there are medics and there are Corpsman. Gotta Go Navy! Still have crazy respect for my brothers and sisters in emergency medicine across the services.
