spoiler: R D is the kid who is with the operator in most of the missions, hes closely related to the resistance leader and the operator as far as I know, I think the operator is the leader's daughter as she does call him otoh-san [father] after that jester kicks his AC. R D Steals that mech later.,. /spoiler but that's as far as I can figure out. though I did make an AC thats as close to his as possible, because the grindblade is really fun to work with. You unlock R D's emblem for beating all of the order missions. Unless that is the resistance leader's emblem. As far as I know, in mission 00 you help stop the Leader figure, but after that he's your CO. As for control scchemes, I run with basic, the only thing I have a bit of trouble with is backwards knee charges
