Historical: Wars of the Republic Era (pdf edition)
Every reference to the 4th Tau Ceti Rangers needs to be changed. Per ER3145, the Rangers were reorganized into the Tau Ceti Lancers around 3100 and first saw action under that name within the first few years of the century. By the time of the Capellan Crusades in 3111, they had been going by the new name for at least a decade.
