I'm an enlisted member of the USAF currently stationed at Hurlburt Field, FL under the AFSOC command (AF special operations command).
To start with um you getting a commision, successfully completing OTS, and becoming a pilot flying anythgin in the USAF is going to take some time. The fact is I have not heard of any Officer leaving after only 5 years, the shortest I have heard so far is 9. I am not aware if these are personal choices but I know if you go Officer a 10 year commitement is most likely. If youw ant to be out by 5 go enlisted.
Even as an Officer you are not guaranteed to become a pilot! I am not sure of all the requirments but i know 20/20 vision is one of them. I have heard of ppl going to OTS to become a pilot and now they are sitting behind a desk, why? AF needs come first it is one of the first things they teach you (just like how I wanted to be stationed ont he west coast). If you do become a pilot They once again choose what you fly! B1's, B2's, F-22's are awesome and all but don't de dissapointed if you get assigned to C-130's =p.... My best friend who i joined with is a crew cheif on the B1-B Lancer in Dyess Texas and i'm a jet engine mechanic on the MH-53 Pave Low helicopter, i wanted straight jets such as the f-22
You are pretty much correct on the pay a 2nd lieutenant makes that starting out I have a chart somewhere but I can't find it. Room and Board um ok if you live in base housing you don't get anything, your house is paid for and you eat free only on base. If you live off base you get BAH (basic allowance for house) and BAS (basic allowance for supplements) each depending on the area that you are stationed and your rank!!!! For example here in northern floria and as an E-3 i make a certain amount living on base, if (when) i move off base I will get that base pay along with $500 for BAH and $250 for BAS a month. SO $750 to pay my rent and eat which isn't too bad considering average apartment rent is $550-650 here. Most people get roommates and get a 3 bedroom house for $850 and end up pocketing a lot of the extra money.
All in all I do not regret being in, I signed up for 4 years then swithed to 6 while still in basic training. I do plan to get out after 6, open my own business and go to school.
If you any any other q's or if I missed anything just PM and ask.
