The Chauchat-Ribeyrolles 1918 submachine gun is a French prototype automatic weapon.
In 1918, they presented a "pistolet-mitrailleur" (submachine gun), meant to be used for close-range protection for the French tank crews. The weapon is based on the RSC Mle. 1917 semi-automatic rifle mechanism. The first trials used a Mannlicher–Berthier clip holding eight cartridges. The trials continued until 1919 with a weapon using the same magazine as the Chauchat. The results were satisfactory but the weapon was too powerful for the intended self-protection use. A mix of standard and tracer bullets was planned to be used to assist in aiming.
Due to the fact that the weapon was a compact carbine meant for self-protection use, it could be considered the first personal defense weapon of all time.
