Background
Based on requirements laid down in 1934, and first seeing production in 1937, the Panzer III was fielded as the primary battle tank of the Wehrmacht at the outset of World War II. Upon engaging the Red Army’s T-34’s and KV-1’s it was evident the Panzer III was at a significant disadvantage. The E-, F-, and G- models were retrofitted with a larger 50mm main gun, which became standard on the –H model along with additional armor bolted to the rear, glacis and front superstructure of the hull. The Ausf. H also received an improved transmission and redesigned sprockets and idlers. Of an initial order of 759 Ausf.H’s, only 308 were produced until April 1941.
