Homeland Security is a fictional organization in the TV series Colony, also known as the Redhats, the Red Berets and the Proxies. They are also sometimes called the Raps, apparently a reference to raptors (the Homeland security logo features a stylized bird of prey).
The fictional organization called Homeland Security was created after the Arrival. They are an oppressive organisation and hunt down the members of the Resistance.
United States Department of Homeland Security
The real-life Department of Homeland Security was created to counter both natural disasters and man-made events. The logo of Homeland Security in Colony bears a striking resemblance to that of the real-life organization.
