You have take in account all the merits of a tank not just one when you discuss efficieny. so i dont understand your logic.
So don't ignore actually meaningful pintle(it does more then you make it sound), don't ignore its armor, don't ignore its range and its penetration.
I'm sick of these double standard comparisons, you guys will make flawed, biased selective comparisons focusing on ger unit weaknesses, completely ignoring the strengths only to enhance your inaccurate one sided opinions.
I swear we WILL have a "Tiger up compared to SU-76 because range" qq thread eventually, because this is the direction you take regardless of how illogical or plain silly you sound, you'll stick to it like it was some holy artifact or ancient scroll of knowledge.
