how long does it take to become a tech sergeant in the air force
Technical sergeant Within air force enlisted ranks, promotion to technical sergeant has historically been the second-most difficult rank to achieve[citation needed] (only the rank of senior master sergeant, capped by federal law, has lower promotion rates[citation needed]) and is the most difficult promotion that most career air force members achieve[citation needed]. A staff sergeant must have served at least 23 months in grade to be considered for promotion to technical sergeant[citation needed]. It normally takes 10â€“12 total years of service to attain this pay grade[citation needed]. Technical sergeants mentor junior enlisted personnel while preparing themselves for promotion to master sergeant, the entry rank of the senior non-commissioned grades.[citation needed]
United States military occupation code A United States military occupation code, or a military occupational specialty code (MOS code), is a nine-character code used in the United States Army and United States Marines to identify a specific job. In the United States Air Force, a system of Air Force Specialty Codes (AFSC) is used. In the United States Navy, a system of naval ratings and designators was used along with the Navy Enlisted Classification (NEC) system: however, on September 29, 2016, the United States Navy discontinued enlisted ratings after two hundred and forty-one years of use. Naval service members thereafter were to be referred to solely by their rank and would hold a Navy Operations Specialty (NOS) instead of a rate.
