One lesson the nations of Earth learned quickly during The War was that gravitic warheads carried by anti-fighter missiles were simply insufficient to penetrate starship deflection grids unless deployed in truly massive numbers. But most fighters lacked the ability to power a gravitic cannon until the Peloran opened up their entire bag of technological gifts for us. That is when so many nations added hyperspace drives and gravitic cannons to their starfighters, and the Texas Rangers followed that trend with their own F-2 Star Furies. Keeping the peace was their primary mission, and sometimes breaking enemy skulls from unforeseen attack vectors was the best way to do that. The Rangers did so with a relish that terrified both enemies and friends alike at times. They considered it their job to teach everyone to never mess with Texas after all.
