A decent advice. I use alot of volks myself but i prefer wurframen as an efficient AI weapon. Sturmtiger has nice antiblob capabilities and can be used against it successfuly, but it depends somehow of how carefull is your oponent to. He will instantly hit the retreat button when he will see your Sturm. What I don't undesrstand is how you succeed in late game to keep pace with soviet armor just with a jagdpanzer and some volks. In 1v1 it may be a solution but passed that, you will probably face dual 85s + IS2 more likely and what you have will not sufise in my view. It's also true that your partner should not sleep. As for jagdpanzer I would like it to have some of Su-85 behavior. More speed and some enhanced view.
In some ways, I get lucky with the Jagdpanzer and Sturmtiger alike- as well as anti-infantry.
It's probably worth clarifying that this build works with the droppable commander Scavenge for the OKW.
The Jagd gets range from Jager light, which has obscene view ranges. Same goes for the sturmtiger- which has a firing range just longer than the usual view range of an infantry unit.
Recon setup team, load shell, remove setup team. It's not a huge hit on a blob, but losing one MG/At gun per minute really, really starts to stack up in the long run.
As well as that, my Volks get infiltration nades- cheap anti-blob and garrision that packs a hell of a punch.
As it happens, though, I'm a 2v2 player through and through. Duel T-34/85 are actually not much more dangerous than T-34/76: most of my AT is infantry based, and 85's suck at killing infantry in the general sense. Keep the Jags spotted for and plink away- if they push, the volks punish them hard.
ISU's/IS2's can be a problem, certainly. Sturmtigers, though, do massive amounts of health damage to them- hitting can be hard, but if you can, well worth it.
Really, by the time the late game rolls around, I hope to be having the fuel for a KT- or at least another Jagd. Scavenge means I can pick up a lot of extra fuel and muni for shrecks and nades- and once I have the shrecks I need, toggle on fuel transfer. The infiltration nades are only 10 muni a pop, thankfully.
If I know it's an IS2 commander I'll sometimes trade the sturm for an ostwind, and mop up infantry that way, so I can get heavier AT. Adapting to the late game is always difficult with that much infantry, but hopefully my Jagd is vetted by then, and vet 4+ Jagds are just scary, scary beasts
