Tanks don't have icons displayed over them. Infantry do.
Well, I'm addicted to tac map, so its likely I'll see icon first vehicle second.
It's no secret that CoH 2 is terrible at communicating important information to the player: we're talking about a game here that has one slot weapon icon per squad yet lets squads pick up two. Most of these problems are too baked in to fix at this point.
This supposed problem with the T-34/76 however is very easily fixed: all that's needed is to remove the fuel tank variants which were added a year or so ago.
Reread that slowly.
But to the point:
It was not an issue for however long time.
It suddenly is, because someone can't tell the difference.
The game should have more variety like that, not less.
If someone is losing the game, because of this, maybe that someone is not the most competitive player around.
I have no issue telling the 76 and 85 apart, the turret's all I've ever needed. I also quite like the visual variety with some having fuel tanks and some not: it's a nice touch like the different voices. But it really is causing confusion I wouldn't lose sleep over going back to just the plain 76.
Taking any flavor like that, that does not even matter for balance is a painful blow for the game.
Same thing with female partisans(never forget).
