There is no doubt at all in my mind that, of all the Services, the Air Force has the most intelligent enlisted people. This is not just theory, it's provable fact:

Take a look at the Army, for instance. When the stuff hits the fan, the young Army private wakes up with a bellow from the First Sergeant. He grabs a set of BDUs out of his foot locker, gets dressed, runs down to the chow-hall for a breakfast on the run, then jumps in his tank. Pretty soon, the Platoon Commander arrives, gives him a big salute, and says, "Give 'em Hell, men."

Now take a look at the Marines. When the stuff hits the fan, the young Marine recruit is kicked out of bed by his First Sergeant, puts on a muddy set of BDUs because he just got back in from the field three hours before. He gets no breakfast, but is told to feel free to chew on his boots. He runs out and forms up with his rifle. Pretty soon, his platoon commander comes out, Gives his Marines a Sharp Salute, and says, "Give 'em Hell, Marines!"

Now take a look at the Navy. When the stuff hits the fan, the young Sailor is eating breakfast in the messroom. He walks 20 feet to his battle station, stuffing extra pastries in his pocket as he goes. There he sits, in the middle of a steel target, with nowhere to run, when the Captain comes on the 1MC and says, "Give 'em Hell, Sailors! I salute you!"

Finaly we come to the Air Force. When the stuff hits the fan, the Airman receives a phone call in his off-base quarters. He gets up, showers, shaves, and then puts on a fresh uniform that he had picked up from the BX cleaners the day before. He jumps in his car, and stops at McDonalds for a McMuffin on his way in to work. Once he arrives at work, he signs in on the duty roster and proceeds to his F-16. He spends 30 minutes pre-flighting it and then signs off the forms. Pretty soon the Pilot, a Captain, arrives and straps into the Plane. He starts the engine. Our Young Airman stands at attention, gives the Captain a sharp salute, and says, "Give 'em Hell, Sir!"
