I don't get your point Jorg. We're talking about AT weapons. And I don't really think that tank will be at "nade throw" distance most of the time. PTRD is in game for a reason.
Right now germans don't have any effective ranged infantry AT weapons. PzB 39 is laughable against T34, GL has very short range and is not effective either. Rifle grenades coupled with GrB 39 seem quite obvious choice for specialised AT role in german team. Especially on maps where tanks can create some space between them and infantry or where approaching flanks is nearly impossible thanks to enemy infantry.
Russians can take out Pz III/IV from 250-300m with side shots. Germans can't actually do anything outside 30m range, unless they just aim for the optics - the only vulnerable thing in T34.
Oh, BTW, I destroying tracks german heavies with PTRD in standard RO was IMO too easy, because german or russian tracks were held together by 1 very long bolt that went through many connecting parts.

Unlike shermans which had those "links" on the sides of the track (so it was possible to tear a track down by destroying 1 "link").
So, if I'm not wrong, PzB 39 is useless even against T34 tracks even if someone manages to score multiple hits to 1 bolt ( since bolt is round and thick I don't think it would get broken in multiple pieces, more likely just dented here and there).
Please correct me if I'm wrong.
