I've gotten an A rank on every mission without buffing a scout and rushing. I find scout mobility slightly less important in this game, now that Scouts can command other units to travel with them, and the APC can carry units etc.

I make sure to kill every enemy ace and kill as many units as possible for the bonus weapons and money.

By the way, there is actually more to A ranking missions in this game. They grant royal weapons based on other conditions, such as clearing enemies. So they actually do reward other strategies besides speed, just through overpowered weapons.

With all that said, Minerva and Odin have personal skills where they get DOUBLE movement. Just something to keep in mind. And there are AP increasing accessories.
