The Republic of Texas Space Force is the primary space combat arm of the Texas military. If you have any doubt of that, simply ask them and they will remove that doubt with great haste and vigor. Their fighters and bases defended Texas installations on Earth and beyond for decades as we entered space and then went on to the stars. All other space faring craft were built to support the Space Force in that mission. The Navy was their taxi service. The Army and Air Force fought under their protection. The Marines did… whatever the Marines did. The Space Force is the best and brightest, and anyone who wishes to fight in space wishes to wear the Texas cowboy hat and spurs. That has always been the focus and the cult of personality that is the Texas Space Force. And to the annoyance of most starfaring nations, and their own countrymen for that matter, they actually managed to live up to it most of the time.
