Final answer:
Army Leaders use several variables to analyze the Operational Environment, including the Moral Law, Heaven, Earth, the Commander, and Method and discipline. They also consider the level of discipline, strength, training, and constancy in rewards and punishments. Adaptation to changing circumstances and political constraints are also important in operational planning.
Step-by-step explanation:
The question delves into understanding what variables do Army Leaders use to plan, prepare, execute, and assess operations when analyzing the Operational Environment. Drawing inspiration from the strategic principles voiced by Sun Tzu in 'The Art of War', key variables for military planning include: The Moral Law, which binds the people to their ruler; Heaven, indicating the natural elements like weather and climate; Earth, relating to the geographical aspects of the battlefield; The Commander, embodying leadership qualities; and Method and discipline, which covers the organizational structure and logistical aspects of the military force. Additionally, considerations of the advantages derived from environmental factors, discipline enforcement, the strength of the army, level of training, and the consistency of rewards and punishments are crucial in the variability of tactics and in predicting outcomes of military engagements.
Furthermore, the structure of modern military forces, with a dedicated general staff, and the focus on achieving strategic superiority, highlight the importance of long-term strategic planning and adaptation to changing circumstances, another variable in operational planning. The considerations extend not only to military but also to political constraints, such as the power and decisions of individual leaders, which may affect military operations at the state or national level.
