Texas Tech was not the first deployment of robots in combat. Many militaries had been sending them on support missions since the turn of the century, and steadily more autonomous robots swarmed over the ground and through the skies as the century went on. And then of course there was the doomed defense of the Japanese home islands from the Chinese invaders. Texas Tech was on a much smaller scale, but it had something the Japanese deployment lacked. Dixie and Twilight.
