He must ensure that they have the proper tools and equipment to perform their mission. But even more importantly, the leader must see to the individual morale and personal welfare of each of his troops. So then, a leader must set the example in job proficiency, devotion to duty, and integrity. Furthermore, the leader must assure that his soldiers are cared for. But leadership is more than this, too.
Leadership is selfless service to one's unit and country.
Leadership is putting one's troops ahead of oneself. Leadership is keeping one's personal affairs in meticulous order. Leadership is stalwart professionalism in the face of adversity. Leadership is all these things and a thousand more. Such a leader will so motivate and inspire his subordinates that they will not only follow him into the pits of hell and back they will be glad for the opportunity to take the trip.
