Complex organizations, such as the armed forces of a particular state, require the most effective and most learned leadership. Leaders or commanders of armed forces must be a professional, truly honorable patriot, skilled to lead the units, both in peace and in the war. The units are trained in certain doctrines and principles, but the success of the unit depends not only on the degree of training. An essential component in leading the squad to victory is motivation of the members. The key role of motivation of the subordinate should have commanders. When the army is trained and motivated, the victory will be lighter and slower. The old folk proverb says "There is no rule in love and war"; which means that victory over the war is not enough, neither motivation nor training is enough. In this paper, through an example of the leadership of the general Erwin Rommel, there will be a failure in the war in spite of the high level of training and equipment, and the maximum level of motivation of the units. The reason for the failure of the war, in Rommel's case, was the lack of understanding the strategic goals of the superiors.
