I don't know how large a town/city you live-in, but if in the USA, go to Government Offices-United States in your local telephone book perhaps near it's beginning pages and see if there is a Recruiting Section under U for United States. My Verizon phone book lists two numbers in two different towns locally for the US Air Force. There are phone numbers also for the Army (they have an aviation branch) also as well as for the Navy (ditto), the US Marine Corps(ditto) and the Coast Guard(ditto) also. Other telephone companies may differ in their phone books. Good luck and I salute you for your early career planning. I was in US Naval Aviation-aircrew from 1950-1959. .
