German general Hermann Balck (1897–1982) was considered to be one of World War II's greatest battlefield commanders. His brilliantly fought battles were masterpieces of tactical agility, mobile counterattack, and the technique of Auftragstaktik, or "mission command." However, because he declined to participate in the U.S. Army's military history debriefing program, today he is known only to serious students of the war.
