The Saint-Chamond was the second French tank to enter service during the First World War, with 400 manufactured from April 1917 to July 1918. Although not a tank by a strict definition of a heavily armoured turreted vehicle, it is generally accepted and described as such in accounts of early tank development. It takes its name from the commune of Saint-Chamond where its manufacturers Compagnie des forges et aciéries de la marine et d'Homécourt (FAMH) were based.
