I want to offer the interesting idea. OT-34/76 tank (Fire-throwing Tank). Those who played Company of Heroes Eastern Front? You remember. There was a T-34/76 Tank fire-throwing? and so I will show you. I think it is necessary to give to improvement of T-34/76 "the fire-throwing case".
And here historical reliability! OT-34/76
How to you my idea? Whether improvement of T-34/76 needs to add against infantry?
