The German Panzers had a unique system for numbering. Each vehicle received a three-digit number painted on both the left and right sides of the turret. The digits represented the vehicles position within the organisation of a panzer regiment: Company, platoon, and vehicle number. The Panzer IV in the photo would be the fourth vehicle of the fourth platoon in the seventh company.
