I also use a RedDragon Perdition gaming mouse with 12 side button. I use the mouse side buttons to change helicopters, p/u troups, settings, radio signals, and zoom in and out in 3rd person view.

In the General Settings set the sensitivity to what you are comfortable with.

I hope this will help you if you are using a joystick.
