Rates are the little-known fastest moving battle armor craft in any squadron of the Battura fleet that appears in both Star Luster and Star Ixiom. They are also good at breakaway attacks, but additionally they are the second strongest offensively after Disruptors. Fortunately, they aren't too common. Getting a Rate in your crosshairs is a difficult endeavor. Your best bet is to chase after one with your thrusters while it is flying away from you and fire at it's back.
