Oh... yes. Put the StuG E to Osttruppen and Commando-Panzer-4 to Community-Defence is better. I was simply in love with the idea of StuG E in hull-down with extra range.
Community-Defense-Commander (Ostwall-Commander)
-Osttruppen (able to build sandbags, wire and light-bunkers)
-Heavy Fortifications (concrete-bunker, tank-traps maybe concrete )
-Commando-Panzer-4
-PaK43 ***
-Sector-Artillery
***Maybe "hull-down" instead of PaK43? In my opinion it overperforms in that commander. Hull-down is a decent ability and it doesn't eats pop-cap. With tank-traps also StuG becomes usefull in hull-down.
Osttruppen-Commander
-Osttruppen (able to build sandbags, wire and light-bunkers)
-Artillery-Officer
-Supply
-StuG E
-Gustav
StuG E should lose the critical-shot-ability. As alternative ability it should get a hollow-charge-burst with 3 shots. Used as Brummbär's bunker-burst with 60range, it performs like old leIG18 hollow-charge. Small aoe, but acceptable pen and damage (maybe like Panzerschreck or like Piat).
Edit: -Osttruppen (able to build sandbags, wire and light-bunkers) infects also relief-infantry and Puma-Osttruppen.
This sounds really neat. I'd love those two commanders arranged like this.
If you want Hull Down on the StuG-E you could stick it in as an ability replacing the inappropriate Critical Shot. A self-hulling down lockdown mode similar to CoH 1.
