My two cents
First, one question. How old are you??
You've already gotten some great advice. The only thing I would contribute is that you compile a list of every Guard and Reserve unit out there. Contact every one of them. Certainly have your preferences, but you never know which unit will need someone yesterday. For instance, we had a guy drop out of OTS last year. He was replaced as quickly as the system allows because we have several people interviewed and ready to go.
One other thing. Pardon me if I step on your toes, but do you want to serve your country and quite possibly get shot at?? The Reserve Forces are great furlough protection, true. It is much much, much more than a job, though. There's a pretty gosh-darn good chance you'll spend a significant amount of time in the desert. You'll quite possibly miss birthdays, holidays, and other events.
Anyway, I wish you the best of luck. Our nation's Reserve Forces are a top-notch organization. You will work with true professionals, make life-long friends, and serve your country.
One big difference you'll notice between this and the airline world is the camaraderie in a squadron. The airline is a job. True, you make some friends there but it is still just a job. Your unit is a brotherhood. I don't think any of our Reservists/airline pilots would disagree with me.
By the way, that is a magnificent avatar!!
