The '''BR55 Service Rifle''' is an infantry [[battle rifle]] in service within the armed forces of the [[United Nations Space Command]].{{Ref/Reuse|Enc22}}{{Ref/Book|Id=EVG|EVG|Page=21}} Among UNSC service personnel, the BR55 has accumulated a number of nicknames including the "'''Monkey Wrench'''", "'''BR'''", and the "'''Big Boy'''".{{Ref/Book|Id=Enc09|Enc09|Page=305}}{{Ref/Book|Id=Enc11|Enc11|Page=318-319}} It is notable for its powerful three-round burst fire and accurate 2× scope, making it more efficient at farther ranges than the [[MA5 series|MA5 series assault rifles]].  


==Introduction==
==Overview==
The BR55 Battle Rifle is a good all-around combat rifle that replaced the [[M6D Pistol]] in [[Halo: Combat Evolved]]. It is the older variant of the newer [[BR55HB SR Battle Rifle]] and is available in [[Halo 2]].
===Design details===
The BR55 Service Rifle is a gas-operated, magazine-fed, mid-to-long range weapon capable of three fire modes;{{Ref/Reuse|EVG}} semi-automatic,{{Ref/Reuse|Enc09}}{{Ref/Reuse|Enc11}} fully automatic,{{Ref/Novel|Oblv|Chapter=9}} and a three-round burst-fire.{{Ref/Game|Id=H2|H2|[[Battle Rifle]] in-game weapon}}{{Ref/Reuse|Enc09}}{{Ref/Reuse|Enc11}} The weapon is most commonly fired in the latter of these modes.{{Ref/Book|Id=H2M|Halo 2 manual|Page=10}}{{Ref/Book|Id=H2LEM|Halo 2 Limited Collector's Edition manual|Page=13}} The rifle has a bullpup layout, with a detachable 36-round box magazine loaded behind the grip and trigger, with a safety switch located above the handle. While serving to reduce the weapon's length, the rifled barrel of the weapon extends its total length to {{Convert|89.9|cm|in}}. It is typically equipped with a three-pronged [[Wikipedia:Flash suppressor|flash suppressor]], though this attachment can be swapped out for others such as a [[suppressor]].{{Ref/Level|HW2|Gatecrashers|Detail=Mission select artwork ([[:File:HW2-Odsts-1.jpg|File link]])}} As with the other weapons in [[Misriah Armory]]'s battle rifle line, the BR55 fires [[9.5x40mm]] [[M634 Experimental High-Powered Semi-Armor-Piercing|M634 HP-SAP]],{{Ref/Reuse|Enc22}} and 9.5x40mm SAP-HE.{{Ref/Reuse|EVG}}


==Summary==
The BR55 is fitted with an optics rail above the barrel, complete with a mounting point for a [[telescopic sight]]. By default, the weapon is equipped with a so-called (and retroactively-named) "[[classic sight]]",{{Ref/Game|H5G|List of REQ cards|REQ card|Detail=Halo 2 Battle Rifle description|Quote=BR with Classic Sight. Reliable firepower never goes out of style. Battle Rifle with full-screen zoom.}} capable of x2 magnification.{{Ref/Reuse|Enc22}}{{Ref/Reuse|H2M}}{{Ref/Reuse|H2LEM}} It features no iron sights.
The BR55 Battle Rifle is a gas-operated, magazine-fed, mid-to-long range weapon capable of semi, burst, or automatic fire and was put into service by 2525 at [[Harvest]]. Due to difficult aiming caused by fully automatic fire, both variants have been restricted to three round bursts. It fires the M634 9.5x40mm X-HP-SAP round in three round bursts (or in fully automatic fashion as seen in Halo: Arms Race) from a 36 round magazine and has a scope with a 2x magnification. It does reasonable damage to enemies being able to kill most within a few bursts. Its accuracy and range are also reasonably high, being able to hit a target from medium to semi-long ranges.  


==Physical Description and Appearence==
Overall, the weapon is considered to have high accuracy and high rate-of-fire, leading it to be popular among UNSC service personnel.{{Ref/Reuse|Enc09}}{{Ref/Reuse|Enc11}}
The BR55 is a bullpup, fully automatic (Except in Gameplay), UNSC rifle that fires the 9.5x40mm X-HP-SAP round (see below). It fires from a 36 round magazine which fits flush in the receiver. The receiver is built directly into the underside of the butt of the gun and is located behind the grip (known as a bullpup configuration).  


This titanium alloy weapon is gas-operated with a rotating bolt and therefore must be cocked before the first round can be fired. 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 mag 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.  
[[File:Whitebkgrdrifle.jpg|thumb|The BR55 was one of the standard infantry rifles of the UNSC during the Covenant war.]]


The BR55, having a rifled barrel, has is 89.9cm long and is fitted with a scope for increased accuracy. The scope is mounted on a carrying handle. The safety is also located above the handle of the weapon.
===Usage===
While newly introduced into UNSC service at the onset of the [[Human-Covenant War]], the BR55 quickly came to dominate all aspects of the military - becoming an extremely popular rifle throughout most of the military's branches.{{Ref/Reuse|Enc22}} While formally designated a battle rifle, in practice the weapon fulfils the battlefield role of a [[Designated Marksman Rifle]],{{Ref/Reuse|BR55DMR}} and by [[2548]] had entirely eclipsed the pre-existing [[M392 DMR]] in all UNSC service except for the [[UNSC Army]]{{Ref/Reuse|EVG}} - with the [[BR55HB battle rifle|BR55HB]] upgrade fully-replacing it.{{Ref/Book|Id=EncDMR|Enc11|Page=316}}{{Ref/Site|Id=WPDMR|URL=http://halo.xbox.com/en-us/intel/featured/gallery/dmr/c0dfea7c-87fa-4224-82ff-c44d93b73f03|Site=Halo Waypoint|Page=DMR|LocalArchive=Archive:Halo_Waypoint/2009 to 2014/Universe/Weapons|D=21|M=08|Y=2011}}{{Ref/Book|Id=Enc22DMR|Enc22|Page=171}} Although the heavy barrel variant was an upgrade of the BR55, in practice the two operate almost identically.{{Ref/Reuse|EVG}}


==Ammo==
As such, by [[2552]] almost all soldiers in the UNSC had trained in use of the BR55 - ensuring that what defects the weapon has are somewhat mitigated. By this time, the weapon was considered one of the standard firearms in use by UNSC forces.{{Ref/Reuse|Enc09}}{{Ref/Reuse|Enc11}}
It is interesting to note the ammo used for the Battle Rifle. It uses a new [[9.5mm x 40]] 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 [http://en.wikipedia.org/wiki/7.62x51_NATO#Development too much recoil] because of the rounds high power, which made it hard to fire fully-automatically in assault rifles. While the BR55's larger 9.5 mm round would be heavier and would thus presumably generate even more recoil than the 7.62 mm NATO, this is not necessarily the case. Since the Battle Rifle's rounds have a noticeably shorter case length than the 7.62 mm NATO (40 mm vs. 51 mm), they most likely contain much less powder than the 7.62 mm NATO, which would yield less muzzle energy and thus less recoil, making the weapon more manageable.


However, the size of the ammo would have a problem fitting in the 36-round magazine of the current Battle Rifle. If a [http://en.wikipedia.org/wiki/Heckler_%26_Koch_G3 Heckler Koch G3] (which is chambered in 7.62mm x 51) 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 7.62mm x 51 with a rather "small" magazine size, which looks to be smaller than the Battle Rifle's magazine.
==Operational history==
While battle rifles began to see popularity throughout the UNSC beginning in the mid-2400s prior to the [[Insurrection]],{{Ref/Book|H4EVG|Page=61}} the BR55 did not enter service until the onset of the [[Human-Covenant War]] in [[2525]].{{Ref/Reuse|Enc22}} The weapon was prototyped as the [[XBR55 battle rifle]] around the time of the [[First Battle of Harvest]], and was in the hands of [[SPARTAN-II program|Spartan-II]] supersoldiers by December of that year.{{Ref/Comic|Id=HCD1|HCD|Issue=1}} During these early encounters with the [[Covenant]], BR55s also fell into the hands of [[Insurrectionist]]s of the [[United Rebel Front]].{{Ref/Reuse|HCD1}} As the war progressed, the battle rifle proved itself an extremely popular weapon particularly in the service of the [[UNSC Navy]] and [[UNSC Marine Corps|Marine Corps]], in which it all-but replaced the older M392 marksman rifles. By [[2548]], the introduction of the BR55's upgraded model the BR55HB fully-replaced the M392 DMR in all services except for the UNSC Army.{{Ref/Reuse|EncDMR}}{{Ref/Reuse|WPDMR}}{{Ref/Reuse|Enc22DMR}}


'''Note:''' Please see discussion about the further speculation about this ammunition at http://halo.wikia.com/wiki/Talk:BR55_Battle_Rifle
The BR55's popularity ultimately contributed to the design of its successor models, the [[BR75 battle rifle|BR75]] and [[BR85 battle rifle]]s.{{Ref/Reuse|Enc22}}{{Ref/Site|URL=https://www.halowaypoint.com/en-us/universe/weapons/battle-rifle|Site=Halo Waypoint|Page=Battle Rifle|D=14|M=06|Y=2021}}


==Influence==
==Gameplay==
The BR55 is largely based on the French standard issue [[Wikipedia:FAMAS (rifle)|FAMAS]] assault rifle, and also has features resembling the H&K G36 and by association the U.S. Army's prototype [[Wikipedia:XM8 (rifle)|XM8]] rifles. Other weapons that may have influenced its design are the SA80, the SAR-21, and Steyr AUG because of their bull pup and scope layouts.  
{{Linkbox|gameplay=yes}}
===Advantages===
The BR55 has reasonably high power, a decent rate of fire, and high accuracy with an electronic 2× 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 if you're within range a red dot will appear in your reticule. 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. Against vehicles like the {{Pattern|Wuzum|Spectre}} or {{Pattern|Karo'etba|Ghost}}, an experienced player can easily take out the driver, rendering the vehicle immobile, however, this is harder with the Warthog.


[[Image:XM8_Assault_Rifle.jpg|right|thumb|200px|The XM8 Assault Rifle was one of the weapons that influenced the BR55 Battle Rifle.]][[Image:Famas_Assault_Rifle.jpg|right|thumb|200px|The FAMAS Assault Rifle was one of the weapons to influence the BR55 Battle Rifle.]]
In ''[[Halo 5: Guardians]]'', the BR55 provides a slightly faster weapon switch and reload time compared to the [[BR85 battle rifle#BR85N Service Rifle|BR85N]]. Most notably, however, the BR55 has higher bullet magnetism, which allows targets to be hit with less-than-perfect aim.


===Disadvantages===
At longer ranges, it is necessary to minimize strafing movements when firing to avoid "splintering" the shot grouping too much. Since each "shot" is actually 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 Carbine, or get up to medium range. The Carbine has the same degree of firepower, and it lacks the splitting effect although it is slightly less accurate. This also affects accuracy when firing from a moving vehicle such as a [[M12 Force Application Vehicle|Warthog]] (especially when firing at a 90-degree angle from the vehicle's heading).


==Advantages==
The BR55 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 [[Sniper Rifle System 99C-S2 Anti-Matériel|Sniper Rifle]]. It is also not effective against [[Sentinel]]s, 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.
Designated the BR55 Battle Rifle, it has reasonably high power, a decent rate of fire, and high accuracy with a 2x magnification scope; it can be used to deliver three-shot-bursts at medium ranges. In [[multiplayer]], four full bursts to the head will kill a fully-shielded opponent, assuming standard [[shields]]. This weapon will kill an unshielded enemy in a single headshot. This requires that only one of the three rounds from a burst hit 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. Right after you shoot however, it is possible to only shoot one shot rather than 3 bullets with a melee attack to disrupt the burst.


==Disadvantages==
Compared to most other UNSC firearms, those using the BR55 have access to limited amount of ammo as they can only three spare magazines, not including the loaded magazine in the rifle.
At longer ranges, it is 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 greatly reduce accuracy. 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).
==Non-canon and dubious canon appearances==
===Silver Timeline===
{{Notice/Silver|category=no}}
BR55 battle rifles are used by [[Silver Team/Silver|Silver Team]] and other UNSC personnel in battles against the Covenant.{{Ref/YouTube|Id=HTVOT|5KZ3MKraNKY|Paramount+|Halo The Series (2022) Official Trailer|Y=2022|M=1|D=30}}


The Battle Rifle is not as effective at close ranges, nor is it particularly effective against [[Elites]] on higher difficulties due to the slow rate of fire. Each bullet also acts as a tracer which gives away the shooter's position. Also, the range is limited compared to the Sniper Rifle. The Battle Rifle is also not particularly effective against [[Flood]] [[Combat Forms]] due to its slow rate of fire. It is also not effective against Sentinels, and does negligible damage against vehicles.
==Trivia==
*On the side of the BR55 opposite the charging handle there are two Chinese symbols, "猴王", which translate to ''"Monkey King"''.
*On the level ''[[Quarantine Zone]]'' in ''Halo 2'', the player can acquire a BR55 from a dead Marine that, when reloaded, can have a total of 236 spare rounds instead of the normal 108 spare rounds.
*In the ''Halo 2'' E3 Demo, the BR55 was the only weapon shown used in making a melee combo, a feature that was originally meant to be in the final version of the game 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 zoomed.
*Like the [[SRS99C-S2 AM sniper rifle#SRS99C-S2 AMB|sniper rifle]], the BR55 is modeled without a trigger in ''Halo 2''.
*The BR55 was featured in Bungie's 30th anniversary event as the solar pulse rifle BxR-55 Battler in ''Destiny 2''.


== Tactics for Covenant ==
==Gallery==
[[Image:Whitebkgrdrifle.jpg|200px|right]]
{{Linkbox|gallery=yes}}
*[[Grunts]]:
Grunts are slow and clumsy, and lack any form of shielding. A single headshot or a couple shots to the body will kill them. Due to the nature of the Battle Rifle's burst fire, it is possible to kill up to three Grunts in one burst (though very unlikely).
 
*[[Jackals]]:
Not as effective as against Grunts, as the bullets bounce straight off a Jackal's Energy Shield. When confronted by a Jackal with its shield in defense position, fire a well-placed shot through the small notch, and, as the Jackal recoils from the wound, finish it off with a headshot. Also, in close-quarters combat, it is recommended to first melee the Jackal, and then finish it off with a headshot when it recoils from the blow.
 
*Jackal Snipers:
At medium range, the rifle is an effective anti-sniper weapon, giving suppressive or covering fire. Since sniper Jackals do not use shields, they can be easily dispatched with a well-placed headshot or a couple shots to the body. As always, it is important to always use proper cover when engaging a Jackal sniper. Be careful you don't get sniped if you are forced to stand in the open, though, and be sure the Jackal doesn't recover and fire off a shot. This is extremely important for Legendary battles.
 
*[[Elites]]:
The Elite's energy shield is a great defence to the Battle Rifle. On Normal difficulty, a basic Minor Elite takes four full bursts to the head to kill, while Major Elites take six and Ultras take 12. However, unshielded Elites of any rank will die from a single headshot. Try to keep the rifle levelled at its head, and keep firing till 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.
 
*[[Brutes]]:
You can kill a Brute with 3 headshots, as the first 2 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. (Note: The only stage in which Brutes can be fought with a Battle Rifle is [[High Charity (Level)|High Charity]]. The weapon can be acquired from the Flood Combat Forms in that level.)
 
*[[Hunters]]:
Dodge behind them, and fire as many bursts as possible into their back before they turn around. Be careful when fighting an enraged Hunter, as they can backhand you and kill you with a single strike. It can take quite a few bursts to kill a Hunter, however, especially on higher difficulty levels. It is not recommended for killing Hunters, a weapon such as the SMG or even better yet a sniper rifle is more suited for this job.
 
*[[Drones]]:
The Battle Rifle is not as effective against Drones, as they are extremely agile fliers, which makes them hard to hit. Furthermore, they are not vulnerable to headshots, and they often attack in swarms. Wait for them to land on a surface, then fire at them. They can take several bursts to kill, the exact number depending on the difficulty level (e.g. it requires two bursts on Easy and Normal).
 
==Tactics for Flood==
When fighting [[Combat Forms]], aim for the [[Infection Form]] in their chest to kill it in a single shot. This will leave the body intact and ready to be taken over again, so it is advisable to shoot off the arms when you have the opportunity. It is also possible to kill a Combat Form by firing at the junction of the host's neck and the tentacles sprouting from it's chest. If a Combat Form you are shooting at has shields, it will take much more to kill it. The Battle Rifle is also effective for killing Infection Forms and [[Carrier Forms]].
 
== Fully Loaded Battle Rifle? ==
On the Level [[Quarantine Zone (Level)|Quarantine Zone]] in Halo 2, the player can find a Battle Rifle from a dead UNSC soldier that, when reloaded, can have a total of 236 rounds of ammo total. A few players have speculated that this is the "full" combat load for the Battle Rifle, as the player can normally carry only 108 spare rounds.
 
== Glitches / Cheating ==
The Battle Rifle may be used in several [[glitches]]. Although they can be used with all weapons, the BXR weapons glitch allows a user to melee, cancel the animation, and then fire, by tapping B (melee), X right afterwards, and then R (the right trigger/gun). This causes an instant kill to a shielded opponent (Elite in campaign or opponent in matchmaking).
 
Another glitch is the RRX, also known as the double-shot. When you press R (the right trigger) twice without pausing followed by pressing the X button right after the pressing of the second R, instead of firing a three-round burst followed by a pause, it fires six bullets without pausing, simulating automatic fire. After successfully pulling off the glitch, your weapon reloads but without any reloading animation. The drawback with the glitch originally was that once you did the double shot, you were reloading the weapon and therefore could not interrupt it and start firing the weapon again to perform another double shot. However this was solved by tapping the Y button twice to switch your weapon and to quickly switch back to your battle rifle, which interrupted the reloading procedure and you, could thus start double-shooting again. It takes four bursts from the battle rifle to the head to kill a target, so successfully tapping RRXYYRRX while accurately firing gave you the ability to kill an opponent quickly, but it is very difficult to master.
 
There is also the RRYB, an instant kill glitch where you press the right trigger twice, immediately followed by pressing Y (which switched to your other weapon) followed by pressing B (melee) all while running towards your target. It is essentially a BXR but in reverse and you fire two shots instead of one.
 
Constant fire - This glitch is not easy to perform, but not hard either. The player must not have host connection of the party else it doesn't work. First, fire one bullet of the BR, next throw a grenade straight away, and then tap reload twice or three times quickly before resuming firing, constantly. If it works you should be able to fire all your ammo without reloading. (RLXX(X)RRRR)
 
Glitching with the BR55 is, again, a glitch, and therefore is considered cheating.  Battle Rifle glitching was unintentional in game development, and was not a predesignated form of gameplay according to the developers.  Game tournament holders such as MLG also consider this an improper way to play, and will disqualify a player upon use of any gameplay glitches.<ref>http://www.mlgpro.com/?q=node/43925</ref>

== Trivia ==
* On the side of the Battle Rifle, (opposite side to the bolt) there are three Chinese symbols. Some people have stated that it may mean "The Monkey King".
* The Battle Rifle variant in ''Halo 3'' is called the BR55HB SR Battle Rifle. The "HB" most likely stands for "Heavy Barrel".
* The Battle Rifle was originally supposed to shoot single rounds in its zoomed mode in Halo 2 based on the [[Zanzibar]] play video before its released, it was later changed to contain the normal three shot fire mode.
* Bungie was not happy on how the M6D Pistol and the [[MA5B]] behaved in [[Halo: Combat Evolved]]. They complained that the M6D behaved more like a rifle and the MA5B behaved like an SMG. Thus, in [[Halo 2]], the [[M6C]], BR55, and the [[SMG]] were born. [[Robert McLees]], a weapons designer in Bungie, commented, "Now we have a rifle that behaves like a rifle, an SMG that acts like an SMG, and a pistol that acts like a pistol."
*This weapon was first introduced in Eric Nylund's Halo: First Strike novel. It was noted that this rifle had "a longer barrel and stock, with a cut down muzzle shroud." "A scope was mounted on an optics railing along the top of the rifle." Spartan-043 (Will) once commented on the rifle, "Auto zoom, nice."
*The Battle Rifle seems to be a prototype in 2524.  This variant of the weapon has a 60 round capacity, which is apparently reduced in later iterations. The only soldiers who wield them in their original state are [[Staff Sergeant Avery Johnson]], [[Staff Sergeant]] [[Byrne]], and their two militia marksmen, one of which is the famous [[Wallace A. Jenkins]].

"When nothing else gets the job done, the BR55 Battle Rifle will do."
— Halo Encyclopedia: The Definitive Guide to the Halo Universe[5][2]

The BR55 Service Rifle is an infantry battle rifle in service within the armed forces of the United Nations Space Command.[1][3] Among UNSC service personnel, the BR55 has accumulated a number of nicknames including the "Monkey Wrench", "BR", and the "Big Boy".[5][2] It is notable for its powerful three-round burst fire and accurate 2× scope, making it more efficient at farther ranges than the MA5 series assault rifles.

Overview[edit]

Design details[edit]

The BR55 Service Rifle is a gas-operated, magazine-fed, mid-to-long range weapon capable of three fire modes;[3] semi-automatic,[5][2] fully automatic,[6] and a three-round burst-fire.[7][5][2] The weapon is most commonly fired in the latter of these modes.[8][9] The rifle has a bullpup layout, with a detachable 36-round box magazine loaded behind the grip and trigger, with a safety switch located above the handle. While serving to reduce the weapon's length, the rifled barrel of the weapon extends its total length to 89.9 centimetres (35.4 in). It is typically equipped with a three-pronged flash suppressor, though this attachment can be swapped out for others such as a suppressor.[10] As with the other weapons in Misriah Armory's battle rifle line, the BR55 fires 9.5x40mm M634 HP-SAP,[1] and 9.5x40mm SAP-HE.[3]

The BR55 is fitted with an optics rail above the barrel, complete with a mounting point for a telescopic sight. By default, the weapon is equipped with a so-called (and retroactively-named) "classic sight",[11] capable of x2 magnification.[1][8][9] It features no iron sights.

Overall, the weapon is considered to have high accuracy and high rate-of-fire, leading it to be popular among UNSC service personnel.[5][2]

The BR55 was one of the standard infantry rifles of the UNSC during the Covenant war.

Usage[edit]

While newly introduced into UNSC service at the onset of the Human-Covenant War, the BR55 quickly came to dominate all aspects of the military - becoming an extremely popular rifle throughout most of the military's branches.[1] While formally designated a battle rifle, in practice the weapon fulfils the battlefield role of a Designated Marksman Rifle,[4] and by 2548 had entirely eclipsed the pre-existing M392 DMR in all UNSC service except for the UNSC Army[3] - with the BR55HB upgrade fully-replacing it.[12][13][14] Although the heavy barrel variant was an upgrade of the BR55, in practice the two operate almost identically.[3]

As such, by 2552 almost all soldiers in the UNSC had trained in use of the BR55 - ensuring that what defects the weapon has are somewhat mitigated. By this time, the weapon was considered one of the standard firearms in use by UNSC forces.[5][2]

Operational history[edit]

While battle rifles began to see popularity throughout the UNSC beginning in the mid-2400s prior to the Insurrection,[15] the BR55 did not enter service until the onset of the Human-Covenant War in 2525.[1] The weapon was prototyped as the XBR55 battle rifle around the time of the First Battle of Harvest, and was in the hands of Spartan-II supersoldiers by December of that year.[16] During these early encounters with the Covenant, BR55s also fell into the hands of Insurrectionists of the United Rebel Front.[16] As the war progressed, the battle rifle proved itself an extremely popular weapon particularly in the service of the UNSC Navy and Marine Corps, in which it all-but replaced the older M392 marksman rifles. By 2548, the introduction of the BR55's upgraded model the BR55HB fully-replaced the M392 DMR in all services except for the UNSC Army.[12][13][14]

The BR55's popularity ultimately contributed to the design of its successor models, the BR75 and BR85 battle rifles.[1][17]

Gameplay[edit]

Advantages[edit]

The BR55 has reasonably high power, a decent rate of fire, and high accuracy with an electronic 2× 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 if you're within range a red dot will appear in your reticule. 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. Against vehicles like the Wuzum-pattern Spectre or Karo'etba-pattern Ghost, an experienced player can easily take out the driver, rendering the vehicle immobile, however, this is harder with the Warthog.

In Halo 5: Guardians, the BR55 provides a slightly faster weapon switch and reload time compared to the BR85N. Most notably, however, the BR55 has higher bullet magnetism, which allows targets to be hit with less-than-perfect aim.

Disadvantages[edit]

At longer ranges, it is necessary to minimize strafing movements when firing to avoid "splintering" the shot grouping too much. Since each "shot" is actually 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 Carbine, or get up to medium range. The Carbine has the same degree of firepower, and it lacks the splitting effect although it is slightly less accurate. 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 BR55 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 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.

Compared to most other UNSC firearms, those using the BR55 have access to limited amount of ammo as they can only three spare magazines, not including the loaded magazine in the rifle.

Non-canon and dubious canon appearances[edit]

Silver Timeline[edit]

HTV-SilverTeam logo.png
 This article contains information about the Silver Timeline, and is not a part of the established Halo canon.

BR55 battle rifles are used by Silver Team and other UNSC personnel in battles against the Covenant.[18]

Trivia[edit]

  • On the side of the BR55 opposite the charging handle there are two Chinese symbols, "猴王", which translate to "Monkey King".
  • On the level Quarantine Zone in Halo 2, the player can acquire a BR55 from a dead Marine that, when reloaded, can have a total of 236 spare rounds instead of the normal 108 spare rounds.
  • In the Halo 2 E3 Demo, the BR55 was the only weapon shown used in making a melee combo, a feature that was originally meant to be in the final version of the game 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 zoomed.
  • Like the sniper rifle, the BR55 is modeled without a trigger in Halo 2.
  • The BR55 was featured in Bungie's 30th anniversary event as the solar pulse rifle BxR-55 Battler in Destiny 2.

Notes[edit]

  1. ^ The Halo Encyclopedia: The Definitive Guide to the Halo Universe claims that the BR55 battle rifle has a maximum effective range of 200 meters. However, this figure is unlikely given that most 21st century rifles have an effective range far greater than 200 meters. As such, this article assumes that the BR55 has the same range as its prototype, the XBR55.
