Hmm I'm really a foolish noob but I got some impressions after winning some matches playing as OKW:
- be very fast in early game
- use the Kübel for annoying enemy capturing units
- use the Kübel suppressing availabilities for "reserve" a capturing point
- attack aggressive (low distance) with the Sturm Pioneers
- always bring all units to a high vet level (micro)
- hold breath until you can order the fat tanks
It would be nice to hear some opinions about these ideas and get further hints from more experienced players as well.
