'''Sentinel Majors''' are upgraded versions of the standard [[Forerunner]] [[Sentinel]], and serve on the [[Halo Array|Halo Installations]]. They are more resilient and powerful than ordinary Sentinels, possessing gold-colored armor and deadlier blue [[Sentinel Beams]].

==Introduction==
Sentinel Majors are similar to a regular [[Sentinel]] in basic shape and function. Sentinel Majors, however, are gold in color rather than silver, have stronger blue beams rather than weaker orange beams, are protected by a light [[energy shield]], and fire more accurately. They were only observed on [[Installation 05]] during the [[Battle of the Quarantine Zone]]. In the game, they are seen combating [[Flood]] and the Covenant.

[[Sentinel]]s have been known to have been created long before [[Alpha Halo]] was ever conceived. They operated automated facilities such as [[Gas Mine]]s, like the one found on [[Threshold]] for untold centuries before the facility was redesigned to research the [[Flood]]. Therefore it is possible that they were only outfitted for combat after the [[Flood]] was discovered.

In gameplay, they are often seen hovering around [[Enforcer]]s whenever [[the Arbiter]] combats them. In addition, they rarely travel by themselves; instead, they travel in packs of 3-5, as well as "commanding" normal [[Sentinel]]s.

==Function==
The Sentinels are the defenders of the Installations and are controlled by the [[Monitor]] of the Installation. Their primary purpose is to contain small outbreaks of [[Flood]]; however, they can only manage [[Flood]] for a short time and in small quantity. Should an outbreak grow beyond the [[Sentinel]]s' ability to control, [[Enforcers]] and Sentinel Majors are activated by the Monitor of the Installation to assist the [[Sentinels]]. It is also possible that there must be a massive outbreak, like the one seen on [[Installation 05]], to give reason enough to construct these stronger versions.

In combat, their shields are less powerful than that of an [[Elite]]'s, and the beam fired is blue instead of orange-red. It is also more powerful, but its battery drains faster as a result. You can pick up this beam and the normal beam as your primary and secondary weapons. One can tell the difference between the weapons simply by noting that the stronger of the two is gold in color, rather than silver.

Rarely, they can also be seen fixing pieces of [[Forerunner]] material, much like the [[Constructor]]s do. However, this is extremely rare.

==Tactics==
Individually, their relatively low shielding (As compared to an [[Elite]], for instance) is made up by their maneuverability. As with Rangers, they can easily slice through the air, evading slow-moving projectiles (Such as Rockets) and coerce the combatant to concentrate on one at a time. The best weapon for them is the [[Covenant Carbine]] or the [[Plasma Rifle]]. First, the [[Covenant Carbine]] has a pretty strong punch and can penetrate the shielding in one or two shots. Then, in an additional two shots, the Major will go down. For the [[Plasma Rifle]], you will rely upon it's steady rate of fire to wear down the shields rather than take it out decisively. [[M90 Close Assault Weapon System|Shotgun]]s and [[SMG]]s can also be effective at close range, but otherwise human projectile weapons are highly ineffective. When facing these worthy opponents, be certain to have some cover within close proximity-these as these [[Sentinel]]s travel in groups, and can take your shielding out in seconds. Behind cover, use hit-and-run tactics to evade fire. Be sure to take one out at a time, as a wasted effort will be useless - the shielding will still be there, and you will have to take it out all over again. Once you have taken out the [[Sentinel]], however, you can have the extremely powerful laser. This can take out the "legs" of an [[Enforcer]] in less than five seconds, whilst an ordinary [[Sentinel Beam]] takes over double the time. If your shields are down and you are out in the open, crouch (Or do something to evade fire quickly) and then activate your [[Active Camouflage|active camouflage]]. Use this time to duck behind cover and do ''not'' fire in this duration.

==Trivia==
*When a Sentinel Major's Sentinel beam is dropped it takes the color of an average Sentinel beam. When picked up, however, the color is gold like a Sentinel Major and the beam is blue.
*Through the use of [[modding]] the map file of the map [[Quarantine Zone (Level)|Quarantine Zone]] in ''[[Halo 2]]'', you will find that there are three types of Sentinels, one being the normal "Grey Sentinel", one being a "Grey Sentinel with shielding", and the last being the "Golden Sentinel" also with shielding.
*The Sentinel Major beam does not appear in multiplayer.
