Char B1 Bis

The Char B1 bis was a major upgrade to the original Char B1, incorporating thicker armour and a new APX4 turret fitted with a longer-barrel 47mm SA 35 gun. Designed as a breakthrough tank, its concept was heavily shaped by French experiences in World War I. This powerful combination of a hull-mounted 75mm howitzer and turreted anti-tank gun made it one of the most formidable tanks in the early stages of World War II.
