That my original plan but sadly i spend so much fuel on Puma and Luchs and trying to tech to Panzer4
If you end up in that situation again, skip the P4 if you haven't already teched and focus on your infantry force. JT is just such a damn good unit in most 2v2s and this case in particular it really shines.
And i had try to lEIGs, no damg, and got counter barrage to dead and also Soviet Big ass mortal
That's why you have to knock out the forward assembly first. The damn thing heals nearby emplacements passively and makes it difficult to do lasting damage. What it might mean as well is you need more leIGs. If they've sunk like ~2000 manpower to defending their sim city, feel free to sink MP into 1200 MP worth of leIGs yourself, but generally I find 3 to do the job no matter how big the city gets. As to the Soviet mortar, you might just need to displace after barraging.
i try moving up the raks but yeah got own by mortal and infantry(rak can't shoot without having to spot for it and my infantry can't take bofor shots for long),
Use the rak's cloak. Its cheesy as hell, but you can move 3 up under cloak (and I wouldn't suggest getting all those if you're the guy buying the leIGs), one volley an SU-76 then hoof it before the Bofors can do its thing. Its a last resort, you're better off luring the SU-76s out to barrage your arty then killing them while they're away from their Bofors cover. The best way to use a Rak is to cloak and spot for your leIGs though.
i kill like 5 SU with puma but the thing is he still had strong brit camping power to stop the push, even used the breakthough tactic arty on them, miss everything the shell that hit caused no damg
Probably had fuel caches to keep up his production. Depending on the map, you could snipe them with the Pumas. As to breakthrough arty, the best thing about it is the smoke afterwards. You and/or your teammate can use the smoke to run in Volks and flame-nade everything they can.
