Fly. Fight. Win.
That mission is clear-cut and direct, the U.S. Air Force will fly, it will fight and losing is not even in the equation. Some may call it arrogance, and cockiness, however, the Air Force has more than earned it. Never in Air Force history have they had a negative casualty rate, because when your battlefield is the blue horizon, and your target is largely tiny dots or ants below you, with armaments so lethal the U.N. has to step in on how they're used, I think I'd be cocky too.
The Air Force possesses many missions, the Amazon of the armed services, the "Chair" Force remains the superior force of the skies, that much is certain that there is no equal in firepower, the Army has tanks, the Air Force has a tank with wings called the AC-130, the Navy has massive warships with 120mm guns, however, they're limited to water that's deep enough. Sky's only limit to the Air Force and the pilot's ability.
Since September 1947, the United States Air Force has Flown, Fought, and Won.
Today they will continue to Fly, Fight and Win.
