OMNI Enforcer (Oppose Militancy and Neutralize Invasion) is the military force of the Earth Alliance, and is also more commonly known as the Earth Forces. Unlike ZAFT, the military of OMNI Enforcer is tightly organized on a traditional model. Many top officers of OMNI Enforcer, mostly those from the Atlantic Federation are also members of the Blue Cosmos anti-Coordinator group.
OMNI Enforcer uses a Japanese style rank system, officer ranks being shown by colored bands on a member's uniform (taking the form of yellow bands with no, one or two blue tabs at the bottom). Enlisted ranks appear not to be designated, NCO ranks are designated with square devices. Civilian auxiliary members do not wear rank tabs. Some rank insignia in the officer chart are conjectural, based on other rank insignia in a common pattern.
Nine officer, three NCO and three enlisted ranks are known; it is not known if other enlisted or NCO ranks exist or if any warrant officer ranks exist in OMNI Enforcer. In addition, the term "Kanchou" applies to the officer in charge of a ship, and can roughly be translated as captain.
There also seems to be slight color differences between the OMNI Enforcer uniforms of the Alantic Federation and the Eurasian Federation. While the officers of the Atlantic Federation wear white, Eurasian Federation officers seem to have a bluish tint to their uniforms.
