This publication was prepared by a number of German officers after the end of World War II. There were a number of these publications, many of which are in publication in the German Report Series by Naval and Military Press. They are all of significant importance in understanding the way in which the war was fought, particularly on the eastern front. This publication deals with improvisations. 157 of which are described. They range from tactical improvisations such as coping with mud, those imposed in desperation and those demanded by special situations, such as during Operation Citadel. Both offensive and defensive operations are covered, as well as troop movements, and all arms are included. Supply and transport also appear, together with technical improvisation (particularly the pamje wagons and the corduroy road), bridging. deception and movement across frozen lakes. Technical improvisation includes training for arctic conditions, and weapon and equipment ad hoc modifications. Special units and the Luftwaffe Field Divisions are also included, as well as some of the last ditch expedients forced on the Germans at the end of the war. There are 6 black and white maps to illustrate salient points.
