Technical sergeant, “tech sgt” or “TSgt” in informal parlance, is the sixth enlisted rank (pay grade E-6) in the U.S. Air Force, just above staff sergeant and below master sergeant. A technical sergeant is a noncommissioned officer and abbreviated as TSgt (with no period in official USAF and other military correspondence). Official terms of address are “technical sergeant” or “sergeant”,[2] although many use “tech sergeant” in informal situations.
