The Sons of Mars are an independent ally of Caesar's Legion. Once known colloquially in the Mojave Wasteland as the feared Vault 34 Boomers of Nellis Air Force Base, the prophesied arrival of the Courier, the subsequent raising of the Lady in the Water (a B-29 superfortress), and, lastly, their significant participation in the Second Battle of Hoover Dam on the side of the Bull circa 2281, heavily influenced the culturally isolated warlike tribe that previously had no contact with the outside world beyond sporadic artillery shellings of savages. William Harrell rose to power not long after the sickly elders, and with it their way of thinking, passed quietly away into the night, never to return. Under his benevolent dictatorship the Boomers quickly became a prosperous microcosm of Caesar's Legion, growing wealthy through the regular export of local foodstuffs. Home to a population of 615, the Sons of Mars possess combat armor, high quality weapons, military robots, trucks, eight howitzers, and a bomber.
