And how play with this doctrine against OKW?
A good question, and one that I've been trying to work out with mixed success.
Conscripts are still fairly good against small groups of OKW starting infantry, especially with molotovs and good use of cover/flanking. PPShs will definitely help against volksgrenadiers, and maybe even ubers if you can rush them. Maxims may be needed if OKW infantry is blobbing. The strafing run will also help against late game blobs.
A decent OKW player will usually try to catch Soviet infantry off-guard with a Luchs at about 9-10 minutes. Flak half-tracks are less common, since they're harder to use currently. Mines will usually go a long way on tight maps, but you probably need to get an AT gun or two up fairly quickly, as well as AT grenades. OKW also can't build tanks as often as Soviets, so t34 ramming may be particularly effective against panthers and jagdpanzers.
AT guns are quite good against OKW structures, and will help protect your t34/85s, which are less likely to get disabled by AT nades against OKW, although more likely to hit a mine.
