"Each and every noncommissioned officer who sustains the Army of this nation has taken an oath. With the swearing of that oath, you enter into a sacred agreement to support the nation. They support the nation, your leaders and your subordinates through your service. This is reconfirmed in the Soldiers’ Creed, which says, “I will serve the people of the United States and live the Army Values.” Through these acts you have chosen to become first a servant, and through time-in-service and increases in responsibility, an NCO and a servant leader. Servant leadership is one of many approaches to leader development. The term servant leadership has been in use since Dr. Robert Greenleaf wrote the essay, “The Servant as Leader,” in 1970, which focuses on the areas of ethics and ethical leadership. The idea of the servant leader can be traced back even further—more than 2000 years—to China. This can be documented in early Chinese writings: “The sage has no invariable mind of his own; he makes the mind of the people his mind,” Lao Tzu wrote in Tao Te Ching."
