Federal Emergency Mobilisation Administration

The Federal Emergency Mobilisation Administration (FEMA) is a government agency subordinate to the National Preparedness Department of the United States government. Operating as part of Homeland Security, it is a powerful agency responsible for much of the less-than-stellar activities of the U.S. government.

Background
Operating under the provisions of the Revised Homeland Security Act (2012), endowing it with considerable amount of authority over other government agencies, the Administration is one of the principal governmental agencies involved in keeping the United States together. It achieves it through both legal and illegal means, including counter-insurgency operations and establishing detention camps for seditious citizens.

2027
Six months before the main events of the game, a certain Joseph Manderley uses his position at FEMA to both help enable, and to block any in-depth investigation into, an attack at Sarif Industries' main HQ & research facility in Detroit. He is also involved months later behind the scenes in a 'False Flag' attack (and its aftermath) against one of Sarif Industries' primary production facilities, located at Milwaukee Junction.

Adam Jensen visits a supposedly abandoned warehouse in Highland Park to find the hacker that infiltrated the Sarif network. Upon descending into the lower levels, it turns out that it is, in fact, a top secret FEMA detention camp that is being established to hold American dissidents.

Later, between 2027 and 2052, the agency was reorganized and renamed as the Federal Emergency Management Agency.
