Foriegn Volunteers did not just appear late in the war. Several units made up from Western volunteers appeared fairly early.

In the Winter of 1940, hundreds of volunteers from Denmark, Norway, Holland and Belgium were incorporated into two new units. When the flow became so great SS Regiments Nordland and Westland were expanded into the new division named 'Wiking'.

Wiking was in the forefront of the German invasion of the USSR from the first day.

Lets also not forget the foriegn troops serving in the Wehrmacht at the same time too...
