Use of captured equipment has obvious benefits and less-obvious drawbacks. When Axis tanks were captured and could be repaired for use, they were often used in deception operations. A common tactic was for a Soviet tank unit to approach a German position using one or two captured German tanks in the lead. The hope was that the German defenders, recognizing a "friendly" tank, would not fire, or would delay their fire long enough for the Soviet unit to make a close approach.
