The Tarsian War was a protracted conflict involving the Angosians of Angosia III during the mid-24th century. The war was a severe and bloody affair that claimed many lives over several years. This presented a particular problem to the Angosians, who were an inherently non-violent species. In order to surmount this problem, the Angosians resorted to extreme measures under extraordinary circumstances. They forced their soldiers to undergo genetic engineering, chemical manipulation, and psychological conditioning in order become more willing to engage in the violence necessary to end the conflict.
