— Bonus Materials Weapons description.
The Chatellerault is a French light machine gun only available during the mission "Baptism By Fire" in the hands of Vichy French forces. It is more powerful than the MAS 38 submachine gun that the player also has access to, but tends to have a lot of recoil when not aimed down its sights, especially when standing up, so it can be hard to use accurately.
