This monograph examines the importance of a commander's ability to sense the terrain. The discussion relates this ability to the commander's ability to act faster than the enemy. This agility is critical to tactical success. As agility is one of the four tenets of the U. S. Army's fighting doctrine it is important that the Army determine means to improve tactical agility. Developing a sense of locality is one way to promote tactical agility. This monograph examines the relationship between these two concepts and shows that a sense of locality is essential for tactical agility. The discussion begins with consideration of the theoretical and doctrinal aspects of terrain, a sense of locality, tactics, and agility. It includes an examination of the elements of a sense of locality, a definition of tactical agility, and an analysis of the relationship between a sense of locality and tactical agility. To illustrate this relationship two historical battles are briefly described and examined. The first illustration is of Major General Thomas J. (Stonewall) Jackson at the Battle of Winchester during his Shenandoah Valley Campaign in the Spring of 1862. The second is of Major General Norman D. Cota at the Battle of Schmidt in November, 1944. The discussion draws conclusions as to the commanders' exhibited senses of locality and tactical agility. Additionally, the discussion and illustrations provide valuable lessons on means or developing a sense or locality and promoting tactical agility. Finally, the discussion presents suggestions for today's commander on how to apply the noted lessons. The lessons reinforce the need for a thorough study of available information on the terrain and force capabilities, for personal reconnaissance, and for reflection prior to battle on use of the terrain during battle. Additionally, suggestions for training are presented; and the study suggests that commanders view the terrain in terms of its offensive and defensive potential--as a weapon available to him or the enemy.
