MOSMilitary Occupation SpecialtyThe U S Army used alpha-numeric codes to identify a soldier's Military OccupationalSpecialty.Basically, an "MOS" is the job in which the GI was stringently schooled and trainedto perform.The MOS that a soldier was trained, tested and qualified in, was called the PMOS(primary MOS).The DMOS (duty MOS) was the job description they were actually performing at anyparticular time.MOS coding systems were different for Enlisted Personnel, Warrant Officers andCommissioned Officers:Enlisted MOS codes consisted of five Alpha / Numeric characters.The first three indicated a job description.The last two digits indicated rank or relative level of expertise.xxx10 (E1-E3)xxx20 Specialist 4 /Corporal (Specialist 4th Class, E-4)xxx30 Specialist 5 (non troop handling E-5)xxx40 Non-Commissioned Officer (Sergeant E-5, Staff Sergeant E-6, Sergeant FirstClass E-7)xxx50 - Senior Non-Commissioned Officer (E-8, E-9)When the individual had advanced schooling or held a special training skill, a"Special Qualification Identifier" (SQI) replaced the last digit of his MOS.This letter indicated the individual's special qualification.(e.g., If an MOS was 11B4P, this indicated that the soldier was an Infantryman [11B]NCO [4] Parachutist [P].)Warrant Officer MOS codes were 5 Alpha / Numeric digits.The first four Numbers the Officers position, the last character was available for anSQI suffix letter.Commissioned Officer MOS codes were all numerical.Four digits indicated his MOS (e.g., 1542, Infantry Officer)
A PREFIX SQI numerical digit was added to indicated a special qualification (e.g.,71542, Jump-qualified Infantry Officer).Special Note to Post Vietnam Personnel:During the 1980s, The U.S. Army changed the MOS code structure.So, the MOS codes which you see here are now history.Vietnam-era MOS CodesMOS codes starting with:00,000,000060, 600, 600010, 100, 100070, 700, 700020, 200, 200080, 800, 800030, 300, 300090, 900, 900040, 400, 4000Special Qualification Indicators50, 500, 500000, 000, 0000 000General Military Duty0001Duties Unassigned0002General Officer0003"Relieved From Duty, Sick in Hospital or Quarters"0005ROTC Officer Awaiting Entry On Active Duty0006Student Officer0009Special Assignment001A Unqualified in Authorized Warrant Officer MOS002A Patient0030Postal Officer0030Sports Specialist003A Student004A Duties Unassigned or In Transit00BDiver

During the 1980s, The U.S. Army changed the MOS code structure. So, the MOS codes which you see here are now history. Vietnam-era MOS Codes MOS codes starting with: 00,000,0000 60, 600, 6000 10, 100, 1000 70, 700, 7000 20, 200, 2000 80, 800, 8000 30, 300, 3000 90, 900, 9000 40, 400, 4000 Special Qualification Indicators
