I do not get why decorative variants of Black and Grey helmets are so present in the customization in all campaigns when both Tunisan desert and winter white stahlhelms not.
Here I present you how it would look like with an use of editor:
Only issue with those decorations is just that the winter helmets have a totally different model and they aren’t that compatible. So because those are clipping together I guess it would be easiest to take a newer version of stahlhelm and replace the texture to white for it to fit the helmet decorations
(A khaki version instead of that yellow helmet ‘harness’ would look great on those white helmets though)
