Military Occupational Specialty

Military Occupational Specialty (MOS) codes are the categorical arrangement of members of the military.  These codes defined the primary job of the soldier.  These codes greatly expanded during World War II, Some codes changed or evolved, but they are an important but oft overlooked tool for the researcher.   If you have a discharge (DD-214) of a family member, look at box 30.   The code and name for that code are located in this box.   This is the primary job that the person was trained to do.   Maybe you have a copy of a document, for the Army maybe it was a General Order or Special Orders document.  Besides some of the names on the document you might see a 1-4 digit number in ( parenthesis ), these denote their MOS.   Visit the following page for more help with researching a veterans history.
