The largest contingent of A10s are based out of Whiteman Airbase in Knobnoster, Missouri. Its also the same base that houses all the stealth bombers.
My friend is actually home on leave and thats where he is stationed. If anyone knows anyone going into the airforce, tell them NOT to go there if they have a choice. He says its the worst ran base in the US.
The A10s are bad ass though.
