Sure, we can take out barrage from Zis and give it pak firepower or make it cheaper!!!
You are quickly reaching Nullist-level silliness. The post is about when you can't use AT guns.
I don't really think this is an issue since soviets already have a major advantage is close quarters combat thanks to conscripts and their molotovs. While I agree it makes for some boring gaames on Kohlodny, giving soviets strong handheld AT would make it impossible to use German T3.
