Who are Ender's squadron leaders? How do they fare on the simulator?
"How can I work with squadron leaders I never see?" (273)
Much to Ender's surprise and delight, all of his squadron leaders are his most trusted friends and allies from Battle School. The list includes Alai, Petra, Dink, Crazy Tom, Shen, Bean, Hot Soup, Fly Molo, and Carn Karby.
Specifics are not given on each student concerning their ability as squadron leaders, but generally speaking, they are not only the best of the best, but the exact people that Ender can work with to their fullest potential. Bean is, of course, the most like Ender in his thinking, therefore he is relied on far more than anyone else. In many ways, he acts as another think-tank with a brain that functions much like Ender's. Petra, at one point, falls asleep at the controls because she has been pushed too far, and Ender notices other leaders grow sluggish as well.
Both Dink and Alai are mentioned once or twice for consistently good work, but overall, the projected success rate of the group is essentially that failure will not be an option. And, alas, they are successful.
