Yes, Ender was an extraordinary commander of Dragon Army. Before Ender took over, Dragon Army had the reputation across Battle School for losing all of its battles. The name was even considered to be a sign of bad luck for any commander. To make things harder, Ender was given an extremely inexperienced team. He had practically no veteran students to use as leaders. Regardless of these disadvantages, however, Ender was able to create a new set of strategies, including creating smaller teams, and encouraging Bean to use his experimental tactics with wires. This allowed Ender to build a team that was never defeated, not even when the Battle School leadership put the army against unfair odds. Ender was even able to lead Dragon Army to defeat multiple armies in a single day.
