According to the principles of LT/LD (likely referring to military leadership and tactics based on the context of the excerpts provided), a commander's number one priority is to ensure the success of the mission while maintaining the effectiveness and welfare of the force. In the citations mentioned, which draws upon historical military texts and figures, including the principles of Sun Tzu and the actions of Dwight D. Eisenhower during the Vietnam War, this balance is highlighted by the need to manage troop movements strategically (avoiding needless exhaustion), to gather intelligence effectively, and to make critical decisions that could put the force at risk to achieve victory.
