History share of an article describing the "Louisiana Maneuvers" which was a large-scale mostly live, but also constructive training exercise that featured combined arms training in the Southern US in 1941 in Louisiana. In this training exercise, the Blue forces prevailed and showed the promise of proper air support to American Army forces would be critical for an engagement against Germany in Europe. As Army General George Marshall noted, he wanted mistakes made in Louisiana rather than in Europe, which would be at the cost of American lives. Enjoy!
