Read the post again: Go for panzerwerfers if you can. I play 2v2's mostly, where the SU-85 is much, MUCH more spammable, and sdkfz 222's can still outflank the enemy snipers, especially if you send a recon run out there to survey. If the SU-85 shot your scout car before you shoot the sniper away, then you are doing it wrong.
Many times, simply killing that one sniper will discourage the player for building another one, for fear of losing that much manpower. Without snipers, maxims can be taken out with indirect fire barrages and smoke. In fact, smoke will most like force the SU-85 to back up or relocate, because it loses its true advantage: range.
Fist off panzerwerfers are t4, so much too late for the SU-85 stage of the game. I was referring to Pripiyat. On Moscow i dont have trouble with su85's that much, they are still irritating but at least there is room to flank.
The snipers on pripiyat can be hard to deal with since your 221/222 cant really chase them if he has su-85's.
Mortar halftrack, meh i like them, but they are in crappy doctrine and i dont have collectors edition. I much prefer the other doctrines anyways.
All i can think of is using more tellers mid game to stop su85's advancing. This however requires me to secure much of the map early game(so i can plant at the chokes without him seeing) which is a bitch. Using regular mortars vs the infantry and maybe smoke to advance can also work. Perhaps i will have to revert to strafe spamming but i dont like using abusive stuff that will prolly be nerfed in future.
I have said this over and over, it is not that the su85 supported with maxim/sniper/htd scripts or guards on pripiyat is impossible to counter. It is just that it requires more skill to counter than it requires to use, which imo makes it a fairly abusive strat.
