Huh? That´s the "Zeltbahn" camouflage.
The Ostheer Grenadiers would look sOOOOOOOOooo much better if they actually look like the pictures you showed (minus the one picture that is the model of the unit obviously) but there's details that they lack that don't make them look like that... like.... the camouflage in the images you showed looks more like it's on this bad-ass jacket instead of their uniform while the model of the grens looks more like... it's just spray-painted all over their clothes x.x
which... this design does not look very cool at all because of it...and closer to being "silly".... (in what i'm sure is just my opinion of course)
which is sad, because i like Ostheer's weapons and tech and faction design (and that they have more commanders then the OKW) but i just can't get past the way the grenadier models look... i'm weird like that...
you know... looking on those pictures... the camouflage pattern might be different but that jacket thing looks very similar to what the OKW Obersoldaten wear.... What is the exact term that things called? if...anyone knows....or it even has a name....
