Veterancy gain is identical for Cons and Grens.
Its 75% from dmg done. 25% from dmg received.
Grens and Cons do almost identical dmg, and have almost identical survival.
No, and no. In the context of actual gameplay the Grens can spend a good bit of time shooting at suppressed squads that barely even shoot back. And they have rifle grenades that do a lot of damage on impact, whereas a molotov does a very slow burn over time effect that is easily negated even if you don't dodge it. Plus if they get a reasonably priced LMG upgrade their damage output increases exponentially. So for no doctrine and easily affordable munition expenditures they have far superior firepower immediately and a huge increase in survivability at vet 2. Even with a 2 CP doctrinal upgrade the conscripts are still inferior pound for pound and because of the reasons I just listed so they will surely be losing the veterancy war.
We don't want to simply compare LMG performance to vanilla Cons in a "vacuum", do we.
No, we compared them to literally every infantry unit the Soviets have, including upgraded Cons.
If you want some more credibility go play Soviets for a change, your German-only stats qualify you to be nothing more than a theorycrafter.
