The M151A1C was used widely in Vietnam and a large number can be seen in period photos. By contrast the M825 (M151A2 base vehicle) was made in fairly small numbers. With the TOW missile launcher being installed on the M151A2 as early as 1970. The desire to have the M825 lessened, with the US military transitioning to the TOW over the 106mm Recoilless Rifle. 1973 looks to be the last year of production for the M825 (for US use). M825s were made for other foreign governments post 1973.
