proof of concept the NKVD Disruption Tactics sucks.
un upgraded conscripts loose to everything German. what to do? blob against them? big mistake. did you think about using penal battalions? huge manpower drainage. snipers. i have always bad luck with snipers stupid storm(bad luck), sigh. this game was slow. stupid and too simple to be interesting, no big plays, no special moves, just plain unit vs unit combat. hence the name. choosing this commander is dropping your advantage to the enemy.
Unupgraded conscripts are indeed not an option, so if you choose a doctrine that has neither shock troops nor PPsHs, you have 3 options:
1. Rely on snipers to do the killing and only use conscripts as meatshields.
2. Go early T2 and get 2-3 maxims to back up the conscripts and settle engagements in your favor.
3. Use penals as main frontline infantry. This is perfectly viable provided you don't attempt to reinforce them - if you do, they'll indeed drain your manpower. Instead, merge them with conscripts and reinforce those. It takes a bit of extra micro to do so, but otherwise you lose nothing as the basic model for penals has the same stats as the one for conscripts and they do receive better rifles after merging.
I'd say between those 3, there's enough options to make NKVD tactics legit. It might take a little training to figure out which one works for you. Don't judge it based on just a few games.
