Ostheer huge T1 into T3?
Yes, that works on some maps, but OKW gets owned everytime, before they can get their ultra-vet.
On the maps I've mentioned Ost can hardly benefit from their long-range T1 arsenal (cons just YOLO in), and because of the Ost muni sortage getting lmgs and healing/sweepers are delayed. The cost of the teching and the mp drain of the grens is just too much IMO, I always try to keep them in green cover, but the cons just overwhelm my boys
Maybe I need to practice more or stick with osttruppens.
About the T1 --> T3, a quick soviet T2 can deny the armor advantage. Later the call-ins just rolfstomp Ost T3.
