US Air Force 1976 to 1980, US Army 1980 to 1984. I don't think I ever mentioned this before, but yes the first four years of my enlistment were spent in the USAF 30750 E4 Sr Amn. My last duty station was as a Tech Controller in Turkey. Once I realized you could not get promoted in the USAF and I had no desire to remain an E4 Sr Amn then an E4 Sgt (everyone except the high command thought that was weird) before being eligible to test for E5 SSgt. I transferred directly into the Army after my enlistment was up with no disruption in service (This wasn't as easy as you might think). I made E5 SGT in 1981 and E6 SSG in 1983. My last assignment was attached to a USAF security unit in are you ready??? Turkey! I requested Fort Shafter Hawaii LOL. They called me Pops, I was 26 but the only person anyone in the unit had ever seen that served in both branches. Be careful what you wish for. After my second enlistment I got out. I still have all my uniforms both USAF and USA.
