Final answer:
To accomplish PRT missions, NCOs must provide guidance and leadership, adapt to circumstances, maintain discipline by enforcing orders, and show confidence in their men while insisting on obedience to commands.
Step-by-step explanation:
To accomplish the Physical Readiness Training (PRT) missions, NCOs must provide guidance and leadership. This involves setting a positive example for physical fitness, instilling discipline, and understanding the principles of military tactics and strategy. Ignoring the physical fitness of their subordinates, promoting a sedentary lifestyle, and avoiding leading by example would result in poor discipline and could potentially lead to mission failure.
Effective leadership includes adapting to circumstances and employing officers wisely, as well as ensuring that orders are enforced to maintain good discipline (REFRAIN from the violence of fist, tongue, or heart). Moreover, it involves careful estimation of the enemy's strength and not underestimating the importance of the natural formation of the country which could help leverage a tactical advantage (the natural formation of the country is the soldier's best ally). It is also critical that a leader shows confidence in his men while also insisting on obedience to commands, fostering mutual respect and an efficient fighting force (If a general shows confidence in his men but always insists on his orders being obeyed, the gain will be mutual).
