Along with the T-34, the KV series of heavy tanks played a vital role for Soviet forces in WWII. This precision plastic model recreates the KV-1B variant, which was up-armoured compared to the original KV-1, on account of fears about improved German weaponry. The bolt-fastened 25–35mm applique armour gave total armour thicknesses of 120mm on the turret front, 110mm on the turret sides and hull front, and 75–110mm on the hull sides. In combination with the imposing 76.2mm main gun and a 550hp diesel engine, this made the KV-1B (manufactured from July 1941) a daunting proposition for enemy units.
