Officers Junior officers United Arab Emirates Abu Dhabi United Kingdom United States The United States law enforcement ranking model is generally quasi-military in structure. Each level of law enforcement (federal, state, and local) has its own rank structure and insignia, and these vary considerably from agency to agency. There is no nationally set law enforcement rank and insignia structure but they tend to follow similar patterns. Because of that, this is not an exhaustive list. Some departments, particularly small ones, have very few ranks, while large ones have ranks as extensive as United States military rank structures. Federal The U.S. Department of Justice and the U.S. Department of Homeland Security (DHS) contain multiple law enforcement agencies and are the largest federal departments responsible for law enforcement; however, other governmental departments and agencies have law enforcement bodies. Each federal law enforcement agency has a unique rank structure. Many federal law enforcement agencies rank structures resemble military rank structure but have different cogitations regarding responsibilities and duties. In general, all law enforcement groups in United States follow a similar pattern: director/chief, assistant/deputy director/chief, special agent in charge, assistant special agent in charge, supervisory special agent, special agent. Example United States Border Patrol State State law enforcement agencies often have a pronounced paramilitary rank structure with rank titles such as: colonel, lieutenant colonel, major, captain, lieutenant, staff sergeant, sergeant, corporal, trooper. Example Alabama Highway Patrol and Alabama Department of Public Safety County County sheriffs are usually elected, chiefs of county police departments are appointed. In a sheriff's department common ranks are undersheriff, assistant sheriff (large departments), senior deputy sheriff, and deputy sheriff, while in a county police department paramilitary titles may be used, which also are to be found in large sheriff's departments. Example of a sheriff's department Santa Clara County, California Example of a county police department Anne Arundel County, Maryland Municipal/city Municipal or city police departments can use paramilitary ranks or more distinct police ranks, or a combination of both.
