Thanks for the nice feedback Domenic
I love OKW, they're definitely my favorite faction - plan on getting my top 10 back when I'm back in town!
Anyways, I think aggressive OKW play is mostly hampered because of the M15 AA HT being just completely nuts at the moment. Not to mention that aggressive infantry being locked behind expensive tech (Obers) or CPs (Fallshirms) makes being aggressive early on difficult.
That being said, I'll work on a more refined aggressive strat next week but I believe something like: Kubel, 2nd Sturm, Kubel, Volk, 251 Flak, Raketen could work - at least once the M15 is brought more into line (hopefully a range nerf?). The 251 Flak is amazingly strong against Lt openers, plus it is great at camping cut-offs. Unfortunately the M15 just takes the 251 Flak to #RektCity.
The goal of the build would be to send the first Kubel + Sturm to their fuel, the second pair to your fuel and then have the Volk cap up the rear/give support where necessary. Both Kubels could run around protecting each other and forcing retreats really quickly, plus you'd have plenty of repair power around. You'd want to keep them off fuel as much as possible to delay the M20/M15/AT guns as long as possible (since either of these will totally wreck Kubels). Hopefully you could have your 251 Flak in a good spot, guarded by the raketen + 1 schrek'd up Volk. Other muni would probably be put towards mines to further entrench the cut off. I think it'd work really nicely with that fortifications doctrine. In theory you could use your 2nd sturms to wire up your side of most maps to force them into fighting on your terms. And the combination of MG34 + 251 Flak + raketen + mines everywhere sounds fun.
