Here's the ugly truth: the AF can and will do anything to you that suits it's interests. They will change the rules on any contract/agreement, to include retirement and BAH for married members. They can force you to stay beyond whatever commitment you signed. You are nothing but an unimportant cog in the machine that is the AF, replaceable and of trivial value.

What I'm saying is don't go active duty under any circumstances, and for the love of god don't sign anything that says they own you for 10+ years. It's not worth the pain.
