The KV series of tanks were known for their extremely heavy armor protection during the early part of WWII. They were almost completely immune to the guns mounted on the early Panzer III and Panzer IV tanks fielded by the invading Nazi forces. Until better guns were developed by the Germans it was often the case that the only way to defeat a KV was with a point-blank shot to the rear. The ""S"" variant was a lighter variant of late 1942 with higher speed, but thinner armor. A new, smaller, cast turret and redesigned rear hull were used. Kit consists of over 430 parts.
