Replay is gone now, didn't save. It was Road to Kharkov, I tried pushing mostly up the left. I decided to do double sturmpio build for extra rifle AI, so I had 3xVolks, 2xSturms & 1 Kubel. For the first few min mostly pushed up the left and a few units to harass the mid & right. Then obviously my volks harassing are pushed off by superior riflemen so had to retreat. Then brought all my units over to the left to push him off there, which he then does too and my kubel is focus fired to death in 1 second, I didn't know he had a m20 at this point. But because I got the extra sturm pios I didn't have schreks yet since my t2 was still setting up. So then I had to retreat because of M20 and too many rifles (mostly all in the green cover stone walls). Then I get puma out by the time he is nearing my base chasing down my retreating troops after another push on the mid/right, I chase down M20 with puma then 1 shot dead from mine. ragequit.
OKW get really powerful mid/late game if you keep your loses at a minimum and dont let your opponent cap the whole map and stack mad resources in the early game. Basically do your best to survive and dont try to outright kill him until you have a KT and a health army of infantry to support it. Once your kubel was destroyed you should have backed off, got out an mg34 or two, and just try to cap the map or at least harass his cut off, fuel, and munitions. Getting a puma was a good idea but you shouldnt have quit after it hit the mine. You probably had the munitions for schreks by then and you could have gotten a raketen or two.
