Mobile Defense, Mechanized Assault, Ostruppen.
Ostruppen I feel is pretty obviously taken for the Ostruppen for a strong early game.
Mechanized is taken after a strong early game to get an anti infantry tank without teching and this commander leads to a strong late game with a late game heavy tank.
Mobile defense gives a strong early-mid game from increased capping, Ostruppen, Pumas, and the P4 command tank. The defensive smoke is nice to help in armour engagements as well.
