During the defense of Leningrad a well laid trap resulted in a spectacular victory with just 1 tank taking out 22 German Tanks and 2 Anti-tank guns.  Zinoviy Kolobanov commanded his KV-1 to deal a crushing blow to the invaders.  In total, in and around "Tank Alley" 5 Russian KV-1s destroyed 43 tanks.  Despite being repeatedly hit, the thick armor of the KV-1 was key to the success of the operation.
