Alien Universe Wars: List Of Major Conflicts

A dropship and warships exchange missile fire among orbital stations in Frontier War space combat

The large wars in human space were fought between governments and, later, between the Human Sphere and an army from outside it. The Frontier War was the 2183 and 2184 border war between the United Americas and the Union of Progressive Peoples. It was inconclusive: the Union took LV-038 and annexed 61 Cygni, Fort Nebraska was lost, and the Colonial Marines Operations Manual records no treaty. The Rage War was the 2692 invasion of the Human Sphere by the Rage. Yautja ships crossed the Outer Rim ahead of adult Xenomorph armies, and the war ended as a Human Sphere and Yautja victory when the android generals burned and the human dropholes shut. The states that fielded armies in the earlier war are collected under Alien Universe Governments.
