Uhhhh Herluf.....why go AF Reserve when you can go Air National Guard?? Air National Guard takes guys that haven't had previous military flying experience. And this is for all ANG units, not just some, unlike the Reserves. The Unit you get into will send you to SUPT (Specialised Undergrad Pilot Training). As long as you're not eliminated through ordinary pilot training, you're gauranteed the airframe your unit flies once you get your wings. ie If you're sponsored by an F-15 unit, halfway through your wings, you're gauranteed the T-38 track (fighters), then IFF (Intro to Fighter Fundamentals), then an F-15 FTU (Formal Training Unit), then you're in your unit flying F-15's. All you have to do is pass, while the Active Duty guys are fighting for who gets the highest scores to go to fighters, etc.
With guard, you spend a few years full time, then you can go off to do airline flying, but come back to fly fighters/tankers/etc on weekends. That means the fantastic pay of airlines, and the exciting flying of the Air Force, put together! And if you can't get an airline job, you can be a "Guard bum", which means you stay at your unit after your full-time is up, but still try to fly every flying sortie available. You can get a fair bit of flying and a decent salary as a guard bum.
Personally, I'd rather Active Duty. But most enjoy ANG's options.
