No not the stuff I am talking about.
True that the T-34 was a shock to the Germans, but the 50mm gun was not a counter to the T-34, they were added earlier as a result of experiance from the battle of france. Both the Panzer 3H and 3J series was put into production before Barbarossa began, October 1940 for the 3H and March 1941 for the 3J, both were armed with the 50mm L/42 guns. They took part in the invasion though to be honest how many made up invasion force compared to the 3Fs I really dont know.
No thats the problem, the The makr 3J panzer has 50mm L/60 gun aka the long barrel series, which were not put into production until December 1941, which means they didn't show up at the front till at least January 1942. I am talking about the J series with the 50mm L/42.
As for the Panzer 4F, I meant the short 75mm variant not the F/2 long barrel variant. Its just from playing the CM series the variants are kind of lacking in this game. Given I have to use the short 75mm as my TD, would be helpful to have the extra armored versions. Both the E and F series were produced in greater numbers then the C series I am currently using.
