CHAUCHAT

The Chauchat was a French machine-gun produced from 1915 to 1924, and used by the French, American, Greek (as the Gladiator), Polish and Belgian armies, despite the fact that it was a poorly designed and badly made weapon which jammed constantly and subsequently required an almost complete disassembly to rectify. The Chauchat was chambered for the 8 mm Lebel French round, or the 0.30 US Service round. Various other calibre versions were produced. It had a rate of fire of 250 rounds-per-minute and was fed by a 20-round box magazine.
