duty history for a 1903A3.
WW2. most 1903A3s that were actually issued, were issued to non combat troops. a lot of Black troops got them, most of the file pictures of A3s in combat during WW2 are with Black troops holding them, security detail, truck drivers, ect, very few actually were issued to {front line} use.
Korea use. mostly the same, some were used for grenade use.
many were also sent to other countries during the Lend lease program,
