And you would assumed wrong
I don't know if you know this but back in the 80's there was a international treaty call NATO it stand for North Atlantic Treaty Organization to combat the Warsaw Pact, the "communist threats"
Us Canadian Airbornes regularly excercides trainings side by side with U.S. Marines in W. Germany so I can confidently say that I know what I'm talking about.
NATO goes a lot further back than the 1980's. It was made in the late 1940's or early 1950's.
And I have to tell you that US Marines do not regularly train next to Canadian Airborne troops. I was in the Marine Infantry and we never trained with any Canadians. Have Marines trained with Canadians? I imagine they do from time to time.
But when you really dropped the ball was when you mentioned W. Germany. Marines were never stationed in West Germany. Particularly during the Cold War each service had an area to cover. Where Europe is concerned the Marines would deploy to Norway and cover the Mediterranean Sea with their Amphibious fleets. W. Germany was the US Army theater and Marines were not stationed their except maybe a few liasion officers. We trained in Norway regularly as well as various places in the Med.
