The Earthforce Internal Affairs Division is the branch of Earthforce - the armed forces of the Earth Alliance - that oversees the conduct of its members. Due to its acronym (EIA), it is commonly dubbed "Eyes" by Earthforce personnel.
Members of the EIA may be drawn from any of the three Earthforce branches. EIA tests the loyalty of Earthforce members if they are suspected of acting against Earth's interests.
In 2258, Colonel Ari Ben Zayn led an investigation regarding the loyalty of the Babylon 5 staff, specifically Commander Jeffrey Sinclair. He was assisted by Harriman Gray, a Psi Corps telepath assigned to Ben Zayn under the authority of Alfred Bester.
