In the article found here http://www.feldgrau.com/norway.html , this is written:
An interesting and unique national unit actually formed by the German Heer was the Wachdienst Norwegen, formed in 1942 as an auxiliary guard unit of older Norwegian men. Its history is very obscure, and its combat value obviously very insignificant, but the fact that is was formed at all is interesting enough. Other than the Wachdienst Norwegen, no other national units consisting of Norwegian Volunteers was formed by the German Heer.
Correct in a way, except that this unit only consisted of Germans, and no Norwegians at all. To the best, "Volks-deutsche" who had lived here before the war.
