Gotta say, I agree with BDGERJMN... the grass is always greener on the other side(or over the septic tank). Gotta do what's right for you. I bailed really early and really enjoy what I get to do. over 15 years in and haven't missed a Santa's delivery yet(knock on wood). The airlines paid the bills while the guard fed the ego. I just didn't want to be at the end a career and no fallback so that is why I went early. Did the active duty thing, the GS thing(very short) the traditional guard and the airline thing. All of them have their benefits. I really enjoy the time off the airlines allow and not doing the 9-5 thing. I have a lot more time with the ankle biters now than before. That's just me. The only problem with being a GS at a fighter squadron would be the physical problems. Flying till you are 55 in a high G airplane takes it's toll. A lot of neck/back surgeries and mucho deployments. IMHO go ugly early.... beat the crowd.
You can still get some type of military retirement along the way. Good luck
