Wait, what? When did I say the at-st's beside fighters? I don't have AT-AT'S. If you let me have them, I'll just send them to the planet and kill the enemies.

Because you can't just "Swap out" AT-AT space to add additional fighters. An AT-AT hanger isn't designed to take TIE fighters and vice versa. Getting rid of the AT-ATs from the compliment just means no AT-ATs :P
