Char B1 Bis n°552 on the assembly chains of Renault, June of 1940.
Char B1 was a specialized break-through vehicle, originally conceived as a self-propelled gun with a 75 mm howitzer in the hull; later a 47 mm gun in a turret was added, to allow it to function also as a Char de Bataille, a “battle tank” fighting enemy armor.
