"Physical fitness comes under competence, the third of my three basic ingredients of leadership. It plays a great part. My own earlier training at Fort Leavenworth, Fort Benning, Fort Sam Houston with the 2d Division, with the 33d Infantry in the Panama area, and with the airborne paid off in battle-first as a division, then as a corps, and, finally, as an army commander. Because of strenuous and unremitting physical training, I was able to keep up with the best of my troops in the hottest sec- tors and the toughest terrain and cli- mate. Let me mention briefly what I think the standards should be for commanders of large units. The division commander should have the physical endurance, stamina, and reserves of his best infantry battalion commanders, because that is where he belongs- with them a good part of the time; the corps commander, those of his infantry regimental commanders; and the army commander just about the same. And remember this, since no one can predict today when you may be thrown into combat, perhaps within hours of deplaning in an overseas theater-as happened to thousands in Korea, and as I have no doubt to many in Vietnam-you will have no time to get in shape. You must be in shape all the time."
