Some icing on the long-term orders cake
"Long Term Orders": You can go "Active duty" in a Reserve unit either voluntarily or involuntarily. Currently in our C17 world these orders are available in 3, 6, and 12 month increments for volunteers. The paycheck is exactly like the paycheck of a person on Active Duty.
By far, the most money you can make is by being on orders. You will most likely get what we call a cha-ching, or tax free/hostile fire pay each month if you enter Iraqi or Afghani airspace. It can be worth about 5-6 hundred for a 1LT or Capt. In addition to that, you can expect about 8-9 hundred per month in per diem from your "stage trip".
Each situation is different, and worth researching carefully. You also have to use a very accurate Magic 8 ball to determine what the future is going to hold for the unit that hires you - how long are orders going to be available? Who is in line to get them should they be reduced or dry up?
Regarding the post above - 8-9 hundred/mo might be a good ballpark estimate, but it depends a lot on where you are spending that month. Will it be Al Udeid, Manas (both just a few dollars a day excepting the first) or Ramstein (close to a c-note/day)? Find out where the units you are interested in are spending their deployments.
Also worth noting, if you make your home of residence more than one hour away from your unit and don't drive back and forth too much (called putting yourself in 'commute' status) you can get mileage and tolls to and from your house, per diem while you are at work _at your home unit_, and housing based on your zip where you live, not the unit. You can also get reibursed for your hotel stays while at work. We've got some guys who have been at hotels for 3 years! They don't get paid the mileage back and forth, but have mega hotel points. I choose to maximize my time at home and don't play that card. IMHO, it seems a little to close to fleecing... If you are going to be a UPT input like the initial poster, you will probably want to live close to the unit because you will be on a prog tour for a while after upt, but your mileage may vary.
Many many variables to consider. I would cast a wide net, make your package look as professional as possible and do what you can to get to know people in the unit. Just because they are willing to hire you, doesn't mean you'll be happy there. I would also have a backup plan/job. Advice I still haven't taken...
For disclosure purposes, I'm on orders at a non-deploying heavy unit.
