The Republic of Texas Marine Corps’ aerospace elements used a mixture of various small short-ranged spacecraft in the past. They flew bombers, fighters, attack craft, and even armed transports in their missions, but none of them could move between planets. Gravtech and the immense increase in range its full implementation provided made them truly interplanetary craft, but the Marine’s twin aerospace missions remained the same. Support the ground pounders in short-term combat missions flying over targets, and protect Navy starships from enemies that meant them harm. The War brought a new range of hypercapable small craft, and the Cowboys adopted the first prototypes of the F-12 Avenger. It quickly proved that they could move independently of large of Navy warships and engage the enemy at far greater ranges than any previous mission had envisioned. That would change everything for the Marine Corps.
