IOW, the people in question are all independantly wealthy and highly eccentric wankers who are in "ukraine" fighting for the Nazi cause there because they feel that is the right thing to do.....
That was a silly post, you don’t seem to know anything about men volunteering to fight for causes they believe in and fighting Russia is a long time cause for volunteers.
The foreign volunteers in Ukraine are officially part of the Ukrainian armed forces as were the Canadian volunteers who joined the American military during Vietnam or the men who joined the Rhodesian or South African forces or the men who join the French Foreign Legion to fight for France.
