Of French manufacture, the Chauchat 8mm light machine gun was developed in 1907 and subsequently modified in 1915._ It became the French army's standard infantry weapon, and some 250,000 were produced during wartime alone. Weighing under 10 kg the Chauchat suffered from the requirement that as many as four men were required to transport its ammunition (in drums)._ It suffered too from a high unreliability factor, a fact blamed on poor manufacturing standards._ Until the delivery of the Browning machine guns the US army also bought and used the Chauchat guns (having bought approximately 34,000 in 1917). The above description of this gun: was very mild and understating. See, during WWI, the US military in Europe were issued this machine gun, which, among other things, was also made in such a way that the parts were NOT interchangeable. If you saw the cartridge you'd immediately see a problem with the design when you add the trench war factor. Not only that, but not any of the manufactured Chauchat's were exactly the same in performance!!! Why didn't the US issue more of their Browning's (BAR) guns, which were superior? Well, according to archives and History Channel (which is where I am getting all of this) the US thought the Browning SO successful that they were afraid the Germans would get a hold of it, manufacture it, and use it against us. I thought it was perfect example of politics not belonging in military. To this day, they do not know how many lives could have been saved by a simple replacement of the guns.
