The Machine Rifle Model 1915 CSRG (French: Fusil Mitrailleur Modele 1915 CSRG), more commonly known as the Chauchat was the standard light machine gun for the French Army during World War I. It was one of the first light, automatic rifle-caliber weapons designed to be carried and fired by a single operator and an assistant, without a heavy tripod or a team of gunners, setting a precedent for several subsequent 20th-century firearm projects, being a portable, yet full-power automatic weapon built inexpensively and in very large numbers. It is infamous for being prone to jamming and its heavy recoil. Despite this, records show the weapon was instrumental to modern tactics later in the war, especially for clearing machine gun nests and providing supressive fire.
The Chauchat combined a pistol grip, an in-line stock, a detachable magazine, and a selective fire capability in a compact package of manageable weight for a single soldier. Furthermore, it could be routinely fired from the hip and while walking. However, its many design flaws resulted in its replacement in both US and later French service by the BAR M1918 and Mle 1924, respectively.
Like many of the expansion's weapons, the Chauchat has higher damage but slower fire rate. Though offering a three-shot kill at close range, it is outperformed by many other light machine guns at longer ranges.
