Amidst tumultuous international politicking and world war, General of the Army George C. Marshall organized and led Allied forces to victory in World War II. Soldiers, statesmen, and world leaders respected Marshall for his strength of character, political savvy, and strategic prowess. As the Army leans forward into the 21st century in a complex global community, Marshall's strategic leadership still sets a high bar. His personality traits, cognitive approach to leadership, self-development, and achievements validate current doctrine and theories on strategic leadership. Specifically, this monograph examines his words and actions leading up to and through World War II as compared to current Army research on strategic metacompetencies, current Army leadership doctrine, and organizational psychology leadership theories.
