Ahhh bless....if you read the changelog more carefully, you will notice these bonuses are GLOBAL, meaning they affect ALL infantry. Insignificant? I think not... These are in addition to their own vet bonuses units get . This is why a Command squad is such a significant unit in the soviet faction
Yes, I'm aware they affect all Infantry. 15% damage is not significant. Command Squad abilities are important to the Soviets, but these bonuses are not. Its not going to let Strelky contend with Elite Armour Grens, even with their individual bonuses. You're going to need a Sniper, Mortar, or Tank for that regardless. Strelky Vet is basically:10% Accuracy0.75x Received Accuracy while moving32.25% Damage
how is a 15% bonus not significant !?! All of your infantry on the map are now either 15% tougher or do 15% more damage on top of there normal vet.
