Basic German build

This is a build I tested a good bit during the original closed beta release. I used a x3Volk x1HMG opening with a medic bunker, then to tier 2 level. Its a defensive doctrine strat build order from CoH1, but slightly adapted to fit CoH2. The idea is to pick an area of interest, or "AOI" on the given map. This area offers you an advantage, be it higher resource points and or key choke points. This area is where you will be giving the most focus to controlling and defending. The CoH2 doctrine I prefer with this is the Panzer Support doctrine (proper name?). I find the smoke screen and mortar halftrack very useful. Here goes...

Tier 1
x1 Gren.
x1 MG42
x2 Gren. -(Hold off on upgrades early game)
-(Use en masse to capture and defend "AOI")

x1 Bunker -(upgrade to health regenerating)
-(place far enough back to avoid
-Upgrade engineers with flamenwerfer)
-Lay mines on probable enemy routes on the flanks of the "AOI".)

Tier 2
x1 251H/T -(Use conservatively as a mobile reinforcement point for your infantry)
-(If moment of opportunity arises use as fast transport for a infantry (esp. flamethrowers) on flank attacks)
x1 Pnzr.Gren. -(Upgrade with Shreck)

-Remake engineer squad if gone)
-Upgrade lmgs on Grens)

Tier 3
StuGs & Panzerwerfers my friend
x1 Pnzr. Gren (for inf control)

Many things are game specific and im aware of its weaknesses. This strategy has brought me decent success. Any thoughts or ideas for improvement are appreciated.
