One fact I learned recently was the number of former Waffen SS that fought for the French Foreign Legion. I have heard 80% but I don’t think the percentage was that high. But certainly many would have been combat veterans, used to discipline, and eager to get away from a ruined Europe, so it makes sense. And also some were in the US army fighting Guerrilla Warfare against Viet-Cong, eg
Laurie Törni / Larry Thorne.
A Finn who fought soviets during in 1938, later joining the Waffen SS to continue the fight.
Then ended up in US Special Forces during the Vietnam War. Seriously badass guy.
