yup. knowing that you can send that mg home and take the engagement is just huge
To be honest, theres a lot I like about NKVD- radio intercept and commissar are great, and scorched earth is a super cool ability.
But I dont really like the AT overwatch ability, unlike AT loiters it's not guaranteed to do damage if you pull out right away(that's what she said), resulting in a somewhat expensive but very niche ability. Maybe not underpowered but not really great in 1v1s due to that niche nature.
The KV-8 is also one of those tanks that looks super cool on paper but in practice just doesnt have a place. To elaborate:
As your first medium with Sovs(and tbh most factions), 4 out of 5 times you will be grabbing a generalist medium-and basically for the same reasons all other factions get a generalist med as a first tank. But the T-34 has piss poor AT so unless you plan to swarm with them, your next vehicle is going to need to be something with a bit more anti vehicular punch, the Su85. This leaves your THIRD tank open for the KV8, and that is assuming you didn't lose either of the other two before you have the resources. On the other hand, the KV8 doesnt work well with the T-34 swarm because of its poor mobility.
I would recommend replacing the KV8 with a KV1 or some other medium-ish heavy or medium tank.
I know this has gotten a bit off topic from just the commissar abilities.
