Kilfeather glanced at the Whirlwind. "You'll need to be able to get this thing up and down the hill, whether under its own power or by pushing, though pushing might cost you some style points. Anypony, or anything, not in a team section in the trench is still considered 'in play' for the purposes of scoring. That'll be important if you have to mend it mid-fight. Of course, there are some general pauses where nopony's fighting anyways, but those will be too few and far between if you have a breakdown."
