This publication is about winning in combat. Winning requires many things: excellence in techniques, an appreciation of the enemy, exemplary leadership, battlefield judgment, and focused combat power. Yet these factors by themselves do not ensure success in battle. Many armies, both winners and losers, have possessed many or all of these attributes. When we examine closely the differences between victor and vanquished, we draw one conclusion. Success went to the armies whose leaders, senior and junior, could best focus their efforts—their skills and their resources—toward a decisive end. Their success arose not merely from excellence in techniques procedures, and material but from their leaders' abilities to uniquely and effectively combine them. Winning in combat depends upon tactical leaders who can think creatively and act decisively.
