West German soil resounds again to the tread of marching feet and the rumble of armored vehicles--but this time for the preservation of peace. The film presents an eye-witness account of training activities of the Royal Canadian 27th Infantry Brigade stationed at Hanover--Canada's forceful contribution to NATO ground forces for the defense of Western Europe. A sight-seeing tour of German countryside, an intense mock ground attack, and a military parade on Hanover's public square are the main features. Everywhere in the background is the mute eloquence of the last defeated aggression.
