The Brummbär does almost no damage against the emplacement. A OH Panther also turned out to be insufficient, it does almost no damage to the emplacement and is easily penetrated.
Paks take ages when blindshooting and get then easily countered. (Maybe if you get a Sniper with Holdfire to spot.)
Another Idea would be the bunker down ability for tanks, it increases their range, so they should be able to kill is more savely. Didn't test this.
After some time the OH Artillery killed it, but probably my enemy was bad at repairing.
He also didn't had it in reach of a VP, so besides capping the other 2 I could also cap the mid one.
Btw, is the counterbarrage ability still useless?
wasn't he bracing his structure then? bcs it is ridiculous if the Sturmpanzer doesn't have any effect at all.
About counterbarrage, it can be useful in some situations, mainly in camp/arty-spam maps or situations but that is just a personal opinion.
what about the brumbar sturmpanzer IV, wasn't it designed to deal with fortifications like this in the war? though i know it is a bit tricky to get it soon enough since t4 as ostheer is hard to reach, but in teamgames it should be possible i think.
