How does MCDP 1 differentiate between strategy and tactics?

MCDP 1 distinguishes between strategy and tactics primarily by emphasizing the nature and scope of each concept. Strategy encompasses the overarching plan or approach designed to achieve long-term objectives and determines the overall direction of military efforts. It involves comprehensive analysis and consideration of various factors, such as political, social, and environmental influences, in order to formulate a cohesive plan.

On the other hand, tactics are concerned with the execution of specific actions and maneuvers that occur on the battlefield or within specific operational contexts. They detail how forces will engage the enemy and are often responsive to the immediate situation at hand. Tactics translate the strategic vision into action by determining the means and methods used to accomplish specific tasks.

This definition aligns with the recognized military doctrine that strategy is about the "what" and "why" of military actions, while tactics deal with the "how" and "when". Thus, the correct answer effectively captures the distinction between the broad, long-term planning associated with strategy and the immediate, practical execution that defines tactics.
