Police ranks of the Arab Union

All police and other law enforcement agencies of the Arab Union use a set of standardised ranking systems, which differ only slightly between type of force. The ranking system for civilian law enforcement officers was established by the National Police Act, 2001, which effected a reorganisation of the law enforcement apparatus from a centralised to a more federated model, in which the vast majority of domestic law enforcement responsibilities, including all localised policing, was decentralised to each of the 20 republics' own Ministries of Interior; agencies operating under the Arab Union federal government's Council of Ministers, such as the Arab Union Sheriff Service under the Ministry of Attorney-General], as well as [["T" Directorate and "J" Directorate of the the Joint Security Committee, generally handle only law enforcement matters affecting two or more republics or the union's national security.

Below is a detailed outline of ranking standards including insignia used by law enforcement personnel, with each section accounting for one of these standards.

Republican and territorial police
The following ranking system is used by all national police agencies of the 20 republics and all territorial police, including the Nasser City Police, as well as correctional officers (prison guards working for a republic's Directorate of Corrections, each subordinate to the respective republic's Ministry of Interior alongside the police). Uniformed officers wear the rank insignia (which is identical across all agencies) on their epaulettes, and all officer identification cards have rank and corresponding insignia emblazoned below the badge and opposite the officer photo and officer number, allowing plainclothes/undercover officers to easily identify themselves as police officers when needed simply by displaying the identification card which is typically affixed to the interior of the officer's wallet.

Arab Union Sheriff Service
The main law enforcement agency of the federal government, led by the Sheriff of the Arab Union who answers to the Attorney-General of the Arab Union. It is responsible only for federal law enforcement as well as assisting other agencies with major investigations. Also maintains security at international airports and air travel, serves federally issued warrants, and transports dangerous felons and terrorists.

As opposed to the republican and territorial police, which refer to their sworn personnel as officers, Sheriff Service law enforcement personnel are known as "deputies" (نواب nawāb; sg. نائب nā’ib).
