I was just wondering about why the pen is so low for it? Like I’ve Seen some sources and some say either ~430 MM to maybe 300? Like if its too OP couldn’t it just be a separate ammo rack with a limited carry amount?

also its still a solid tank but suffers really bad at frontal engagements

because gaijin has nerfed u.s ammo for no reason

that explains a lot
