The United Nations Space Alliance (UNSA) is an international political organization that handles matters related to trade, travel, land claims and all efforts relating to human space colonization. Their military force is represented by the Solar Alliance Treaty Organization (SATO).
The UNSA was created as a means to control and monitor off-world colonies in order to obtain resources to maintain Earth geo-engineered atmosphere.
The UNSA presumably lost the secession war 30 year before the events of Call of Duty: Infinite Warfare, losing control of Mars, its moons, and several Jovian moons in the process. The UNSA owns a military force equal in strength to those operated by the SDF.
USNA territories include, but are not limited to:
The UNSA appear in Call of Duty: Infinite Warfare multiplayer as a playable faction. The multiplayer announcers are Nora Salter, Usef Omar, and a unknown robot. They always fight the Settlement Defense Front. They appear in all maps.
