Part Three addresses organizational and strategic leaders in additional detail. Both organizations and strategic leaders are still direct leaders. This part describes what makes organizational and strategic leaders unique from direct leaders.

You have to lead men in war by requiring more from the individual than he thinks he can do. You have to lead men in war by bringing them along to endure and to display qualities of fortitude that are beyond the average man's thought of what he should be expected to do. You have to inspire them when they are hungry and exhausted and desperately uncomfortable and in great danger; and only a man of positive characteristics of leadership, with the physical stamina that goes with it, can function under those conditions. -General of the Army George C. Marshall Testimony to the U.S. Senate Committee on Military Affairs (1940)
