Why is everyone hell bound on putting anti tank in soviet T1? German T1 doesn't have anti-tank ... why must soviet have it? If you want to spam Penals because they're boss, what's wrong with just picking Guards/M42 doctrine, building T2 for AT guns, or going for SU76? I don't get why everyone is forcing an AT option into soviet T1 ...
Edit: this just came to me... why not just let Penals have access to AT grenades?
While I myself am uncertain that this Penal PTRS upgrade needs to happen too, I am pretty sure AT grenades on Penals will ensure no one will want to build Conscripts ever again. Molotovs and Merge alone are definitely insufficient reason to built Conscripts.
