"A commander must genuinely love his men and win their affections in return, and when the time comes, he must use that love to cause his men to willingly risk and even sacrifice their lives to accomplish the mission. Here lies the moral imperative of leadership. The leader is entrusted with the lives of his men and accepts unlimited liability for their welfare. The task of bearing such a burden requires more than passive preparation from organizational schooling and mandatory training. Such a task demands passion. Here I speak of passion in the medieval Latin sense of the word: to suffer for love. The passion of a commander is equal parts love, zeal, and a quiet wrath: love for the men, zeal for the lifelong study of the profession of arms and the behavior of men in battle, and the quiet wrath to make the nightmares of our enemies come true."
- Colonel B.P. McCoy The Passion of Command
