If you are a 11B US Army Infantryman, and have attended airborne school. Can you attend air ault school? As far as air ault regiment or unit (im not to sure how you call it, im not in the army yet) is the helicopters you're primary transportation? Or they move around alot in Humvees? For you guys that's been through it, what is the most exiting part of the air ault?
