First of all shermans penetration is 140 and they buffed it from 120 pen to 140 second the 76mm gun itso ne round is good vs infrantry exremly good vs medium tanks and its reload time its crazy can kill an OKW panzer iv with half health
You're right about the pen being max 140. My bad, but that's still more than sufficient to deal with p4s considering how shit p4s are for their price. In your other posts you're stating the 76mm destroys p4s with ease. Indeed it does. So I don't understand why you would like this to be added non doctrinally. It would make USF once again imbalanced to the axis.
