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 Associated 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 was founded after the secession war 30 years before the events of Call of Duty: Infinite Warfare, when Earth lost 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, though unlike the SDF, the UNSA military is 100% volunteer while in the SDF, all capable men are conscripted from age 12. This leads to SDF having 900% more soldiers per capita than the UNSA. However, since the UNSA is significantly more populated than the SDF, the overall total numbers between these two forces should be somewhat equal.
USNA territories include, but are not limited to:
- Mercury Cluster
- Venus Cluster
- Earth Cluster
- Mars Cluster (Formerly)
- Jupiter Cluster
- Saturn Cluster (Formerly)
- Uranus Cluster (Formerly)
- Neptune Cluster (Formerly)
- Cygnus X-3
The UNSA appear in Call of Duty: Infinite Warfare multiplayer as a playable faction. The multiplayer announcers are Nora Salter, Usef Omar, and E3N "Ethan". They always fight the Settlement Defense Front. They appear in all maps.
