Disable Oorah ability when LMG upgrade is bought. I think a DP-28 upgrade for Cons in one commander wouldn't hurt the game. I'm all for diversity.
Don't forget there's Panzerfusiliers who can upgrade to 3x G43 AND pick up up to 2x LMG. They're pretty terminator but they don't brake the game.
This is what I'm bringing with my ideas.
NKVD Rifle Disruption Tactics v.2
0 (PASSIVE) Radio Intercept
Intercepts enemy radio transmissions providing valuable intel on enemy actions.
1 - Commissar Squad
The Commissar provides extra offense and defense to nearby infantry.
2 - (PASSIVE) Conscript Long Range Package
Conscripts can upgrade to replace their rifles with DP-28 Light Machine Guns for better long-range firepower.
Only one DP-28 is allowed per squad and Conscripts lose their Oorah ability.
6 - Fear Propaganda Artillery
Airburst propaganda leaflets make targeted soldiers question the morality of their actions.
8 -Scorched Earth Policy
For the duration of the ability, enemy units in owned territories are bombarded with multiple rockets.
