TW, that video is BS, it misrepresents reality.
The "502nd in their blue UN berets" are a component of the 101st Air Assault Div, as for "UN" troops training in the US, We have been supplying training to other countries that lack space for about 60 years.
As for the Germans ? there have been Panzer (Trning) Div stationed permanently at the NTC and in Canada since Reagan was in office. They don't have enough space for the type of live fire training these areas provide and their Govts pay for it.
And when they talk about "Never before on this scale". It's an out right lie worthy of a democrat.
http://en.wikipedia.org/wiki/Louisiana_ManeuversScope
The Louisiana maneuvers involved half a million men, in 19 Army Divisions, taking place over 3400 square miles (8,800 km²) of Louisiana during August to September 1941.
Around 400,000 troops were divided into two equal armies of two made-up countries. The countries' names were Kotmk (Kansas, Oklahoma, Texas, Missouri, Kentucky) and Almat (Arkansas, Louisiana, Mississippi, Alabama, Tennessee). The armies were also called the Red Army and the Blue Army. These armies were fighting over navigation rights for the Mississippi River.[2]
[edit] Blue Army
The Blue Army set up headquarters in the town of Kinder, Louisiana at the Kinder High School and there is a roadside marker at the location.
