Depends on your base pay and the D of State authorized uplifts for your deployed location.
IT geeks (like me) are making betweek 250K - 300K per year in Iraq and Afghanistan.
Pilots can make the same or more - depends on your background. The top tier military pilots w/ initiative do quite well.
Its an adventure and if you want to have a second life doing something dynamic, exciting, and with a group of people dedicated to making the world safe for all mankind we'd love to have you.
Its not all about the pay- right? If you like / want an adventure this is the time to embark on one.
