However, the T-34 with a crew of 4 has a RoF of 5. This to me seems to be quite incorrect. It should be 2 along with its counterpart, the KV-1.
T-34
Ergonomics
The T-34/76, like many other contemporary tanks, had a two-man turret crew arrangement. This required the tank commander to aim and fire the gun while having to coordinate with other tanks and potentially also being a platoon commander, and proved to be inferior to the three-man (commander, gunner, and loader) turret crews of German Panzer III and Panzer IV tanks, which allowed the tank's commander to concentrate solely on that job.
The loader also had a difficult job due to the lack of a turret basket (a rotating floor that moves as the turret turns); the same fault was present on all German tanks prior to the Panzer IV. The floor under the T-34's turret was made up of ammunition stored in small metal boxes, covered by a rubber mat. There were nine ready rounds of ammunition stowed in racks on the sides of the fighting compartment. Once these initial nine rounds had been used, the crew had to pull additional ammunition out of the floor boxes, leaving the floor littered with open bins and matting and reducing their performance.[
The problems created by the cramped T-34/76 turret, known before the war, were to be fully corrected with the addition of a three-man turret on the T-34-85 in 1944.
The Germans also noted the T-34 was very slow to find and engage targets, while their own tanks could typically get off three rounds for every one fired by the T-34.[
