These are the current military pay tables. You can derive everything you need to know from there.
Raggio knows way more about the reserve pay system than I ever did as a butter bar

irate:
Now, if you're a "reserve bum", you won't be making as much money as your peers on active duty. The reserve pay system is really designed for someone who works a full-time civilian job and just does the military gig on the side. Yes, you can work two, four-hour periods on a single day in exchange for two pay days (basic pay plus incentive pay, no BAH or subsistance allowance, etc). Without those extra allowances, two additonal flight training periods (AFTPs) or just "double teeps", really work out to be about 1.5 times an active duty day worth of pay. Plus, we're currently limited to 48 AFTPs per fiscal year (of which 24 may be AGTPs ["ground teeps"], and further limited to 16 AFTPs per quarter--8 AGTPs). In additon, reservists are guaranteed 48 UTA periods per year and 15 days of annual [active duty] tour. The annual tour and UTAs are mandatory participation, i.e. "one weekend per month, two weeks per year" you always hear about in recruiting ads. The AFTPs/AGTPs are optional, plus you can (are are usually 'encouraged') always put more into the unit's mission. For example, assuming you're out of UTAs/AFTPs/AT and the unit still needs you to fly a mission, there are other ways to fund you--either through Military Personnel Appropriation (MPA) "active duty money" or Reserve Personnel Appropriation (RPA) "AFRC money". At the end of the day, a reserve "bum" probably winds up with the equivalent of 20-25 days of active duty-equivalent compensation per month, or maybe a little more depending on how motivated they are. My point-the government really get it's "bang for the buck" with reservists, because we're only getting paid when we work. If we come in to work every weekday in a given month, Monday thru Friday, we'd only be paid for those days (not Saturday and Sunday like the active duty while they're on their regular "pass", unless we actually went to work on Saturday and Sunday). The advantage, however, is that reservists have alot more freedom over their lives. They have the freedom to pursue other callings in the private sector, or be wherever they want to be without taking "leave". And of course, reservists can say "no" if they're given a trip they don't want. If you're on active duty, Uncle Sam owns your rear end, period dot. The disadvantage is, of course, if you're a bum, chances are you've put just as much (if not more) into your job as your active duty peers, yet you're only paid essentially by the hour. Some people who wish to make the reserves their full-time occupation opt for the air reserve technician (ART) program; they're doing the same jobs, but they're wearing a full-time civil service hat too.
That's probably more than you wanted to know, but I hope you (or at least FrogFlyer) got something out of it.
