United States Coast Guard 

The United States Coast Guard, a life-saving and law-enforcement service, was established as the Revenue Cutter Service in 1790. Currently, it is a branch of the US military, though it is regulated by the Department of Homeland Security. It is often disparaged as being made up of "Navy rejects," but is a vital part of the security strategy of the United States of America

Navy Seaman: You Coasties are Navy rejects!
United States Coast Guard CPO: Yeah, well, we've got the better uniforms. Fuckin' sailorhat wearing loser.
