People keep saying that OKW needs the LiG to make up for their lack of a HMG but most OKW players play a commander that provides them one. People also seem to forget the Kubelwagon.
The gun kills better than the best Soviet mortars of the same value and also instantly suppresses units making infiltration tactics impossible on smaller maps and massing infantry to counter OKW blobs near impossible on all maps.
Only because they're the nicest commanders for OKW with the best utilities. Like fortification doc with Pak43 and bunkers and s-mines
