Imagine cheap shock troopers; however, it only gives three out of six the PPSH.
So if your up against an Ostheer who has set up good positions and you have conscripts with the package and swarm them in numbers they are a nightmare. That is, if you have support like mortars or an SU-76 around. It might be also useful for going up against OKW players who start off heavy with Sturmpioneers.
Now Penals are now good at killing infantry, but giving your conscripts the package increases their close-quarters combat.
My experience with them is limited, since I mostly play USF all the time. However, I do hope someone will probably come into this thread and tell you their experience. One of the best commanders to have for the PPSH package is the Advanced Warfare Commander and since it has the PPSH package and the T-34/85 it is a good combination with the conscripts. There are other commanders who have this such as the Guard Rifle Combined Arms Tactics, Shock Army, and Conscript Support Tactics.
Isn't it 4 ? i don't remember quite well, it has been ages since i haven't played ppsh cons
