This reminds of what our history teacher in secondary school did. He always accurately referred to all parts of the German military branch before, during and after World War 2 by name. Luftwaffe was Luftwaffe, a Wehrmacht Soldier was a Wehrmacht Soldier.
What I mean to say is, if possible the writer of an article should be as accurate as possible. A great benefit of doing the necessary research is that anachronisms and other details like wrong equipment can be pointed out to the reader. It adds to the quality of a page and guarantees that no one will be offended. Watching Wehrmacht soldiers with FG-42 parachute into Alaska with Russian helmets and French camouflage uniforms probably isn't that obvious at first
