The A10 Thunderbolt II (Or more commonly known as the warthog) is the USAF's close air support legend, now coming to the S.T.A.F. The A10 is so good at close air support mainly because of one thing: It's 33mm gatling gun. This thing fires 70 rounds of AP/high explosive/incendiary ammo the size of bottles in one second. That's what makes it's iconic BBBRRRRRRRTT sound.
