Enforcer Sentinel

Enforcers are large robotic automatons designed by the Forerunners.

Introduction
Enforcers are most likely designed to contain major Flood outbreaks on Halo Installations. They are also seen guarding key locations such as the entrances to the Sentinel Wall. Enforcers are produced by the flying Sentinel Production Facilities.

Enforcers are protected by an energy shield, but it only seems to protect the "front" on the machine. It is armed with rapid firing Pulse Beams, and mortar-like projectiles. It is also equipped with mechanical grabbing arms can pick up entire vehicles if the driver is careless.

Combat
The Enforcer's energy shields can absorb more damage than a normal Sentinel. The shield, which only guards the front area of the machine, is nearly immune to ballistic weapons, similar to the Jackal shield, but is weak against plasma weapons. It is also very strong, capable of withstanding up to two Scorpion shells or two to three Wraith shots.

The Enforcer's red projectiles (similar to the Covenant Needler) are usually not a threat to players as they are very easy to dodge. However its mortar projectiles are much more dangerous and can quickly kill you.

If you can shoot off its small needler shooting arms, and the small pair of energy mortars on its back, it will start to fire an invisible Sentinel Beam. The beam, although invisible, the damage it does to walls can still be seen, and the sparks emitted show that the beam is a blue sentinel beam.

They were only observed on Installation 05.

Trivia

 * Enforcer's front shields form a Marathon style logo.
 * The "crystalline guns" fire rounds similar to the Needler. Bungie did plan for another Sentinel weapon to be usable by the player referred to as the "Sentinel Needler" and "Red Needler". For reasons left to Bungie, this weapon was not in the game, but the Enforcer's weapon is most likely the same gun.
 * A misprint in the Official Halo 2: Strategy Guide made by Piggyback and Prima Games, mistakenly called the Enforcer a "Sentinel Major."
 * In the Spanish version of Halo 2 the Enforcer is called "Ejecutor" because enforce is to make complete and enforce in spanish is translated to execute or "Ejecutar".
 * The Enforcer looks very similar to the machines seen building in the comic titled "The Cradle of Life"
 * The Enforcer's did not appear in Halo 3.
