Bunk,
Here is a rundown of the ways to get paid on the Green side, I cant imagine Blue side being too different.
1-drills the one weekend a month, as mentioned above you make O-4/30 x drill periods (4 is normal, 5 is also done if you work friday night
2-AFTP Additional Flight Training period-this is a "I come in to fly" on the green side it is TMS dependant, for rotoray wing guys 1.5 hours of lfight time = one drill so most guys fly a 3.0 and get paid two days of base pay and flight pay as an O-4 (around 400 or so)
3-RMP- its late cant remember the acronym but it would be like I came in to do ODO or something else = 1 days pay for one days work
4-ATP-Aviation Training period, i.e came in to be on a stan board etc 1 days pay for one days work
5 ADSW-Active duty Special work, you come on Active Duty for a set period of time to do something airshows etc. You rate bsaic pay, flight pay and if over 30 days BAH. IF you are over 50 miles you get per diem and a hotel room
6 Annual Training-your two weeks a year, you make O-4 and flgiht pay
I am sure Blue side is similar (bet all the accronyms are slightly different), your drills and AT are yours and not dependant on the Commands money so do those last. ADSW AT and RMP depend on a given budget. ADSW is attractive to furloughed Airline guys and if you have a good rep it will be offered to you first.
Hope this helps, our unempoyed/underemployed guys make between 35-50K doing reserve stuff.
Edit: Flyspy beat me to it, sounds like the two are similar
