Char B1 bis

Upgrading the Char B1, the Char B1 bis had thicker armour and an APX4 turret with a longer-barrelled (L/32) 47 mm SA 35 gun, giving it more anti-tank capacity alongside the 75mm hull-mounted howitzer. French experiences during The Great War influenced their belief a breakthrough tank would be needed in future conflicts, hence the design of the heavy Char B1 and B1 bis. However, slow speed and high fuel consumption made it ill-adapted to the more fluid style of warfare being fought at that time. With the fall of France, the victorious German military captured 161 Char B1 bis tanks and repurposed them under the nomenclature Panzerkampfwagen B-2 740 (f). Several were also converted into flame-throwing tanks.
