Beginning with a small number of African American units in the Regular Army and National Guard, the AGF organized and trained many more, including the African-American 92nd and 93rd Infantry Divisions, and the 2nd Cavalry Division.
When the M3 anti-tank gun proved to be a less than optimum anti-tank weapon, the Army began development of tank destroyers - self-propelled tracked vehicles which mounted a gun capable of engaging a tank, but which were faster and more maneuverable because they had thinner armor than a tank.
