Groundcrew - AAC groundies tend to be 'streamed' now. Gone are the days of jack of all trades, master of fuck all. They can be streamed as signals, drivers, refuel/re-armers, stores/logistics. AAC is a Combat Arm so you get to do all that stuff whilst ragheads try to reduce your life expectancy. Slighty further into your service, you may be selected to become and Aviation Rearcrewman (Door Gunner) so you can actually shoot the ragheads if you want. If you are especially handsome and hung like a baboon, you may be selected to become a pilot.
If you tell me that was a bone answer, I'll find where you live and fuck your dog to death.
