From watching Bonzo Madrid, Ender learns both from what Bonzo lacks and what he does well. Bonzo's skill is in organization and discipline. When he becomes a commander, Ender incorporates an emphasis on order and hierarchy into his system with Dragon Army. However, Bonzo is also short-tempered and acts tyrannical, such as when he makes the foolish rule that Ender cannot participate in the battles in spite of his skill. Ender's approach to leadership is different in that, after a short period of drill sergeant-style behavior, he generally shows respect to his subordinates and trusts them to carry out the assignments he gives. He does not allow his emotions to overcome him or affect his relationship with his army. Ender is capable of thinking of the same person both as a model and as a warning.
