Army Men(and Women)

Well, my youngest son is home for two weeks for Home Town Recruiting before going to Korea for his first assignment in the Army. While here, his older brother decide he is going to join up and has signed up for 6 years. He leaves in 10 days for South Carolina. They took their friend to talk with the recruiter today, and took our 16 year old daughter with them. She came home and is saying she is going to join up when she turns 17 and graduates from high school early this fall. While I don't have anything against the Army, why can't at least one join the Air Force! And why all three pretty much at once!
