MAT-49 [SEP] service entry
MAT-49
The MAT-49 was a submachine gun which was developed by French arms factory Manufacture Nationale d'Armes de Tulle (MAT) for use by the French Army and was first produced in 1949.
Development.
In 1949, after evaluating several prototypes (including a collapsible design from Hotchkiss), the French MAT factory began production of the MAT-49 9 mm submachine gun. The MAT-49 used a machine stamping process which allowed the economical production of large numbers of submachine guns, then urgently required by the French Government for use by
Army, French Foreign Legion as well as airborne and colonial forces. 
Production continued at Tulle until the mid-1960s, then switched to the Manufacture d'Armes de St-Etienne plant (MAS), where the weapon was produced until 1979. In that same year, the French armed forces adopted the FAMAS 5.56 mm NATO assault rifle, and the MAT-49 was gradually phased out of service.
Usage.
The MAT-49 saw widespread combat use during the First Indochina War and the Algerian War, as well as the 1956 Suez Crisis
