The '''BR55 Battle Rifle''' is a [[United Nations Space Command]] infantry service rifle, first seen in ''[[Halo 2]]'', although it has been in service since 2525. It is the older of the BR55 series rifles. It is most notable for its powerful three-round burst fire and accurate 2x scope, making it more efficient at farther ranges than the Assault Rifle.

==Design Details==
The BR55 Battle Rifle is a gas-operated, magazine-fed, mid-to-long range weapon capable of semi-automatic and burst-firing modes. Prototypes of the Battle Rifle were used in [[2525]] at [[Harvest]], but it entered active service in 2524. The weapon is canonically capable of fully-automatic fire, but only the three-round burst mode is encountered in game. In Halo 2 the Battle Rifle fires the M634 9.5x40mm X-HP-SAP round from a 36-round magazine, though in Halo 3 the weapon utilizes the 9.5x40mm KURZ<ref>''[[The Art of Halo 3]]'', Page 57</ref>. Additionally, the weapon features a [[scope attachment]] capable of 2x magnification. It does reasonable damage to enemies, being able to kill most within a few bursts (normally four when enemy is fully shielded), and easily land headshots on unshielded targets, resulting in a one-hit kill. Its accuracy and range are also reasonably high, being able to hit a target from medium to semi-long ranges. It is highly recommended to always have one on hand on higher difficulty levels. 

The BR55 features a [[bullpup]] design that fires a three round burst from a 36 round magazine UNSC rifle that fires the 9.5x40mm X-HP-SAP round. The magazine housing is built directly into the underside of the stock of the weapon and is located behind the grip. 

This titanium alloy weapon is gas-operated with a rotating bolt. Therefore, the charging handle must be racked before the first round can be fired; this will put a round into the barrel. The charging handle used to chamber the round is located on the left side of the weapon and does not move during operation. Once the first round is fired, the gases from that round—and those to follow—impinge upon a gas piston, which pushes back the bolt carrier, rotating the bolt inside and continuing to chamber rounds until the magazine is empty. Once the magazine is empty, the charging handle (even though not illustrated in-game) can either be pulled back and locked or it can be fully cycled after a fresh magazine has been housed. If it is pulled back and locked, then it must be pushed forward once a fresh magazine is housed to chamber a new round. The magazine release button is located on both sides of the gun with an arrow pointing down towards the housed mag in the stock. The ejection port is located on the right side of the weapon. There is also a fire selector on both sides of the ammo display. 

The BR55, having a rifled barrel, is 89.9cm long and is fitted with a scope for increased accuracy. The scope is mounted on the optics rail. The safety is also located above the handle of the weapon.

===Ammunition===
It is interesting to note the ammunition type used for the Battle Rifle. It uses a new [[9.5mm x 40|9.5 x 40mm]] Experimental Round. The [[Wikipedia:7.62×51 NATO|7.62 x 51 mm NATO]] round is a rather high-powered round used on the MA5B and on modern-day marksman rifles and machine guns. The 7.62 mm already has a history of having [[wikipedia:7.62x51_NATO#Development|too much recoil]] because of the round's high power, which made it hard to fire in full-auto in assault rifles. Despite the Battle Rifle's shorter case size, the increase in diameter actually increases the amount of powder present. The level of recoil would be enough to drastically decrease accuracy and inhibit the ability to fire controlled bursts for standard Marines, although for Spartans it should not be a problem.

However, the size of the round would have a problem fitting in the 36-round magazine of the current Battle Rifle. If a [[wikipedia:Heckler_&_Koch_G3|Heckler Koch G3]] (which is chambered in 7.62 x 51mm) has a standard magazine count of 20 and be the size that it is, it would be hard to see a cartridge much wider than the 7.62mm fit inside of a magazine of the Battle Rifle's size and with a capacity of 36 rounds. The Battle Rifle's magazine would have to be about twice as long as it actually is to hold that many rounds. This is a continuous pattern with UNSC assault rifles as a similar instance occurred with the MA5B. The MA5B has a magazine of 60 rounds chambered in the 7.62 x 51mm with a rather "small" magazine size, which looks to be smaller, than the Battle Rifle's magazine.

===Advantages===
Designated the BR55 Battle Rifle, it has reasonably high power, a decent rate of fire, and high accuracy with an electronic 2x telescopic sights attachment; it can be used to deliver three-round bursts at medium ranges. In [[multiplayer]], three body shots and one head shot will kill a fully shielded opponent, assuming the player does not have an overshield. This weapon will kill an unshielded enemy in a single head shot. Target the head and a dot will appear in your reticule, indicating that you are aiming at their head. This requires that only one of the three rounds, from a burst, actually hit and kill an enemy. Therefore, it is possible to kill up to three unshielded opponents in a single burst if they are grouped close enough to each other, though this is an uncommon occurrence. However, right after you shoot, it is possible to only shoot one round rather than three bullets, with a melee attack to disrupt the burst.

===Disadvantages===
At longer ranges, it's necessary to minimize strafing movements when firing to avoid "splintering" the shot grouping too much. Since each "shot" is really a three-round burst, certain movements can break up your shot's grouping, and could greatly reduce accuracy. To avoid this, either swap it in for the Covenant version (Covenant Carbine), or get up to medium range. The Carbine has the same degree of firepower, and it lacks the splitting effect. This also affects accuracy when firing from a moving [[vehicle]] such as a [[Warthog]] (especially when firing at a 90-degree angle from the vehicle's heading).

The Battle Rifle is not as effective at long ranges. Each bullet also acts as a tracer which gives away the shooter's position. Also, the range is limited compared to the [[SRS99C-S2 AMB Sniper Rifle|Sniper Rifle]]. It is also not effective against [[Sentinels]], and does negligible damage against vehicles. Neither is it an effective weapon at close range, as the low fire rate and average stopping power of the weapon makes any fully-automatic weapon far superior in close-quarters combat.

The BR55 can have a certain disadvantage against [[Flood]] combat forms, in particular the Human variant. Both forms have a certain vulnerable spot on their bodies. This is the area of the body that the Infection Form has taken home in. For the [[Sangheili]] variant, this is the upper-center of the chest. The human variant takes hold in the left shoulder area, noted by a large bump. The Combat Form can be brought down with a single shot by hitting this area, but the Battle Rifle is virtually useless shooting anywhere else.

===Influence===
The BR55 is largely based on both the [[wikipedia:QBZ-95|QBZ-95 Chinese-designed assault rifle]] and [[Wikipedia:FAMAS|FAMAS French Assault Rifle.]]. Introduced in 1995, the QBZ-95 represented a radical departure from previous Chinese infantry arms. The new rifle used a bullpup configuration and was chambered for the lighter 5.85x42mm round. Both the BR55 and the QBZ-95 also notably lack a fully automatic firing setting, but can similarly mount optional rifle accessories on the carrying handle. It also has some resemblance to the G36 and G36C and looks similar in appearances like the XM8 due to the curved front and mounted scope instead of iron sights. The FAMAS assault rifle is a bullpup configuration like the QBZ-95 and has been in service since 1978 and fires a 5.56x45mm NATO round.

==Tactics==
===[[Campaign]]===
[[Image:Whitebkgrdrifle.jpg|thumb|The BR55 is an all-around infantry weapon for [[UNSC Marine Corps|Marines]] in [[Halo 2]].]]
*The BR55 is the all around go to weapon when facing [[Covenant]] forces, it can effectively take down [[Grunt]]s and [[Jackal]]s with one well placed three shot burst.
*Given that the bullets bounce straight off a Jackal's Energy Shield, when confronted by a Jackal with its shield in defensive position, fire a well-placed shot through the small notch, and, as the Jackal recoils from the wound, finish it off with a head shot.
*The Elite's energy shield is a great defense to the Battle Rifle. Try to keep the rifle leveled at its head and keep firing until it falls dead. It is advisable to soften an Elite up with grenades, melee attacks, or a Plasma Pistol's charged shot before engaging them with a Battle Rifle, especially on higher difficulties. 
*You can kill a Brute with three head shots, as the first two bursts will knock off the helmet, then the following headshot will kill the Brute. However, shooting a Brute in the torso is not particularly effective due to their extreme resilience.
*When engaging a Hunter, dodge behind them, firing as many bursts as possible into their backs before they turn around. Be careful when fighting an enraged Hunter, as they can backhand you and kill you with a single strike.

===[[Multiplayer]]===
*The BR55 replaces the [[M6D]] from Halo:CE.  Most of the tactics remain the same; however, you do not need to lead your shots as much as the M6D due to the fact that the BR55 relies on a Hitscan mechanic.
*The BR55 paired with the [[Plasma Pistol]] makes a good [[Noob Combo|combo]]. Paired with a [[SRS99C-S2 AMB Sniper Rifle]] the Battle Rifle will flip the gap of medium to long range.
*Use the "four-shot tactic": three to the body and one to the head. This will result in a kill, as long as the opponent doesn't have an active Overshield.
<!--Please refrain from adding BXR or any button glitch to this part of the article, they are just that, a glitch, and while you may view it otherwise the creators have said otherwise since there is no button combo in Halo 3. If you wish to add BXR please visit: http://h2.halowiki.net/p/Main_Page-->

==Trivia==
*On the side of the Battle Rifle, opposite side to the charging handle there are two Chinese symbols, "猴王", which translates to Monkey King. This is a nod to the [[M6D]], which has the Kanji symbol for [[7]] on the side.
*The BR55's first canonical appearance was in [[Joseph Staten]]'s novel [[Halo: Contact Harvest]] in the novel it is explained that the first prototype came out in 2525. It has a 60 round magazine,<ref>[[Halo: Contact Harvest]], page 132-133</ref> after the conflict at Harvest the UNSC standardize the BR55 for field deployment.
*On the Level [[Quarantine Zone (Level)|Quarantine Zone]] in ''Halo 2'', the player can find a Battle Rifle from a dead UNSC Marine that, when reloaded, can have a total of 236 rounds of ammo total instead of the normal 108 spare rounds.
*The notorious [[Noob Combo]] is used in the ''Halo 2'' cinematic [[Another Day at the Beach]].
*In the Halo 2 E3 Demo, the Battle Rifle was the only weapon shown used in making a melee combo, originally meant to be in the [[Halo 2|final version]] but was scrapped. It was also shown firing semi-automatically in both the demo and in the E3 2004 Multiplayer Alpha demo in which the semi auto mode was engaged when in zoomed mode.
*The maximum ammo that can be carried for a Battle Rifle is 144, including the ammo inside the magazine with 108 in the magazine.
*Much like the [[MA5B]] and the [[MA5C]], the BR55 and its newer variant, the [[BR55HB SR Battle Rifle]], has a screen with the number of rounds left in the magazine shown in bright blue text. A compass is absent from the screen, however.
*The Battle rifle has the same reloading animation as the [[MA5C]] Assault rifle. 
*Although the BR55 fires three-round bursts, it is possible to find one in which the number of rounds left in the magazine is not divisible by 3. This means that the final burst of the magazine will be just one or two shots.
