NOOSE

The National Office Of Security Enforcement (NOOSE) is an high-end law enforcement organization in Liberty City in Grand Theft Auto IV. It is a consolidation of the Military and SWAT units seen in previous GTA games.

Description
NOOSE is based on the U.S. Department of Homeland Security and is separated into two divisions: the Liberty City Patriotism and Immigration Authority, based on the U.S. Customs and Border Protection, and the Liberty City Tactical Response Unit, based on the NYPD Emergency Service Unit.

NOOSE is called upon to assist the LCPD when the player has a wanted level of 3 stars or higher. Patriotism and Immigration Authority officers are largely similar to the LCPD's in behavior, weapons, appearance and mannerisms. Tactical Response officers, however, are designed to appear as fully equipped tactical squad units, with heavy armor and weaponry.

NOOSE's vehicle fleet consists of modified Police Cruisers, Patriots, Enforcers, Annihilators, and a new Armored Personnel Carrier to be featured in The Ballad of Gay Tony. The NOOSE Cruiser and NOOSE Patriots are exclusively driven by Patriotism and Immigration Authority officers, while the Enforcer and the APC are used solely by the Tactical Response Unit. The Annihilator may appear with occupants from either division.

Basic behavior

 * Tactical Response officers are well protected with body armor and don't lose health very quickly.
 * NOOSE's primary weapon is the Carbine Rifle. The SMG and the Pump Shotgun serve as secondary weapons, and the Pistol is the standard issue back-up weapon.
 * Agents always use good cover (e.g. behind a car, behind a wall, inside their helicopter).
 * They usually move together as a unit.

Trivia

 * A noose is a type of self-tightening knot, most commonly known for the Hangman's knot used in public hangings.
 * NOOSE's seal is a combination on the seals of the Department of Homeland Security and the National Security Agency. The color scheme, border, and eagle is based on the DHS seal, and the shield and key the eagle is holding is similar to the NSA seal.
 * The player may notice that the insignia of NOOSE on the NOOSE Cruiser and NOOSE Patriot is labeled LC Noose. After the capital "L" and "C," the following letters are all lowercase and the second "o" is smaller regular lowercase letter. This may be a reference to GTA III's FBI Car, which is poorly written as Fbi Car.
