Weapon-ships were small autonomous combat craft used by the Forerunners, launched to carry out tasks considered to be beneath the dignity and worth of Warrior-Servants. Deployed from larger ships such as Fortress-class vessels, weapon-ships operated in automated phalanx formations and could be controlled at a ratio of up to a million ships per warrior. The most common of the Forerunners' autonomous combat drones, weapon-ships were classified as small auxiliaries deployed in the millions to serve as scouts, escorts, or shields. Disposable to fleet commanders, they were frequently deployed en masse in battles.
