M6 Spartan Laser

"It's not overpowered, it's an elegant weapon from a more civilized age."

- Luke Smith

The Weapon/Anti-Vehicle Model 6 Grindell/Galilean Nonlinear Rifle (abbreviated W/AV M6 G/GNR), also known as the Spartan Laser, is a United Nations Space Command ground-based, man-portable, directed energy weapon. It is the only battery operated weapon of the UNSC.

It's alternatively known as the Galilean.

Introduction
The M6 Spartan Laser is a shoulder-mounted direct energy weapon used by the UNSC. It fires a potential-to-kinetic powerful red chemical laser capable of destroying vehicles and infantry with one accurate strike. When the trigger is pulled, a harmless red sighting laser is projected on-target along with a charging sound, known as a painter. The Spartan Laser will then charge for approx. three and 1/2 seconds before firing its powerful and destructive burst. As the Spartan Laser charges, the charging tone gets noticeably louder up until the laser is fired. The charging sequence can be canceled without a battery penalty if the target moves out of sight or the wielder needs to change position. The laser is also capable of firing through several players or vehicles, and has a small blast radius, injuring targets within 2 meters of the impact point and toppling light vehicles. It has a downtime between shots while it cools down (approx. 2-4 seconds) and is highly effective at destroying enemy vehicles.

In Halo 3 Multiplayer, if you kill another player with the Spartan Laser, you will achieve a unique medal, the Laser Kill Medal, it is awarded due to the difficulty of having to charge and aim the weapon. The weapon is not available in the campaign until the level The Covenant, which Master Chief begins the level armed with the M6 G/GNR. The Spartan Laser is one of the three weapons powerful enough to harm 343 Guilty Spark in the final level of the campaign. (the other two are the fuel rod gun and rocket launcher.)

Targeting
When the weapon is un-holstered, a shroud over the emitting lens of the laser lifts up to expose it, presumably to protect it from scratches and battle damage when holstered, although the weapon is shown with the shroud up when it is on a person's back. The shroud can be seen doing this when the weapon is un-holstered in first person view if the user looks carefully. The shroud is actuated by a small hydraulic or pneumatic cylinder on the left side of the shroud where it is anchored to the chassis of the weapon. When the trigger is pulled, a harmless red dot is projected on the target and a unique targeting tone is emitted. The Spartan Laser will then charge for three seconds before firing a massive blood-red laser beam that completely destroys the target. In the beta, if the reticle was moved while firing, a scattering of beams would be released, spreading over the targeted area. For the few seconds the laser is fired, the right targeting stick is disabled. However, the beam can be strafed over a larger area if the player is moving while the laser is firing.

The Spartan Laser is equipped with a smart-linked Wyrd III optics suite for increased accuracy and is capable of 2x magnification. Its reticle, whether on 1x or 2x magnifications, features a meter on the right side showing the charge of the laser.

Laser Beam

If the player manages to keep their reticle on their target when the beam fires, the enemy will be killed in one hit. The Galilean "Spartan Laser" can even destroy a vehicle in one hit, however the Wraiths and Scorpions cannot be simply shot at, they must be aimed at differently to get the one shot kill. To do so, the operator of the laser must hit the cockpit of the vehicle in question, except for the tanks. The Wraith must be fired upon from the rear right below the mortar, or directly aimed at the cockpit. The Scorpion must be hit from the side on the area upon which the firing of the 90 mm shells takes place. It is powerful enough to make its way through nine Warthogs but, oddly, only 4 Mongooses parked bumper to bumper. It is also highly effective at destroying Scarab leg joints, although The Covenant is the only mission where this can be done, and it is unlikely the player will keep the Spartan Laser that long into the level without completely draining its battery. . The beam is also known to have high splash damage at its impact point, and around its shot, and also has the capability to over-penetrate, and eliminate multiple targets aligned in a linear trajectory. If the player is facing a wall, an opponent or another obstacle at an extremely close range, the splash damage will instantly kill the operator. After firing, the weapon stops functioning for a brief period of time as it dumps its waste heat. The weapon has 5 shots before a "recharge" is needed.

It is powered by a BA-53635/PLMD non-replaceable battery, which is recharged with a PP-16979/AM-Sh charger. However, UNSC logistics are not sufficiently adequate for the charger to accompany many W/AV M6 G/GNR units in the field.

Trivia

 * In the level "Halo" if you kill Johnson for his Spartan Laser and keep it then you get his from where he shoots 343 Guilty Spark ,you can get two Spartan Lasers.
 * The first level you obtain a Spartan Laser is the level "The Covenant" and you actually get off the Pelican with the Laser in-hand.
 * If you keep the Spartan Laser through the level "The Covenant" and it still has ammo you can use it in the level"Cortana".
 * The two times you can obtain a Spartan Laser in campaign is "The Covenant and "Halo".
 * The term "Galilean" in the name does not refer to Galileo, but to Galilee, a town in what is now Israel where Jesus lived for thirty years of his life. This is a reference to the "Galilean Cannon" a theoretical weapon that used brass rods to launch a final rod at exceptional speeds without any propellant.
 * When a Flood Combat Form wields the Spartan Laser, it cannot shoot you. It is unknown as to why Flood have no intelligence of using the Spartan Laser.
 * On the level Halo, if you pick up Johnson's Spartan Laser, it can have 55, 70, or 85 battery, which is usually impossible to obtain, because each shot takes 20 battery.
 * The Spartan Laser is the most expensive weapon to produce currently known. It costs 218,000.00 cR, more than the cost of four fully armed Warthogs, 134 MA5B Assault Rifles, or over 7,266 M9 Fragmentation Grenades. That means approximately every shot is the cost of one Warthog.
 * The only vehicle the Spartan Laser can't destroy is the Elephant which only appears in the multi-player map Sandtrap. The laser beam, however, will penetrate the armored walls of the vehicle and will damage anything in its way (except for walls or terrain.)
 * On the side of the gun there is a sign which reads "DANGER: Bare live wires". This is also featured on the Missile Pod.
 * The reticle of the Spartan Laser has been changed from the one in the Halo 3 Beta. Instead of four markings pointing inward the circle, the reticle now has a circle with a smaller circle inside of it.
 * In the level Halo of Halo 3, it is possible to use the unlimited Spartan Laser Johnson gives you for the rest of the level. To do this, you must be playing co-op. After 343 Guilty Spark opens the door to the control room, kill Johnson with a rocket/grenade, the flamethrower also works very well if you kept it from earlier. When he dies, quickly keep swapping weapons (Johnson's Laser with your weapon). When you get it far enough, use the Laser and it will have unlimited ammo (do this for both players). Then, just before you fight 343 Guilty Spark, kill each other, leaving your Lasers there. Then fight 343 Guilty Spark and after you do, the Laser will still be there for you to use in the Warthog or Mongoose with unlimited ammo.
 * The Spartan Laser is the 3rd known infantry weapon that can crack the casing of a Monitor the other two being the rocket launcher and fuel rod gun.
 * If you manage to kill a player at the exact time they discharge the spartan laser, the laser will still shoot but it will spin around as if it has lost control.
 * The Spartan Laser penetrates more or less vehicles depending on the type. Up to ten Warthogs can be destroyed by the laser. It will also kill ten Spartan or Elite soldiers for each given discharge of the laser.
 * If you play the Campaign Mission The Covenant on Easy or Normal, there will be a second Spartan Laser near the downed pelican, but it does not spawn when playing on Heroic or Legendary.
 * It is unclear how the W/AV M6 G/GNR was given the battlefield moniker Spartan Laser; it is possible that the first wielder of the weapon was a SPARTAN-II super-soldier, or that is was given the name as a reference to the SPARTAN-II's or the soldiers of Sparta's superiority.
 * The side of the laser has the Norse symbol for "Gungnir" etched into it, which was the mythical spear wielded by the god Odin in Norse Mythology.
 * The laser seems to trail off forever when fired into the sky, much like the Sentinel Beam. However, the beam of both weapons does end, usually at the invisible walls of the playing area. The laser beam on Sandtrap covers over 75% of the width of area (fired at a 45 degree angle).
 * When fired at the ground, there will be more than one impact spot, which indicates that there are four separate beams.
 * The writing near the back of the Spartan laser on the right hand side of it reads 06 Galilean, but on the other side this is backwards. This is probably because Bungie designed only one half of the Spartan Laser's skin and mirrored it for the other half.
 * If a Marine is given a Spartan Laser, when you retrieve it from them it's power supply will have recharged itself. The amount of added charge varies depending on the amount of time they were holding it.
 * A hit with the laser is not always a guaranteed kill. If the laser does not strike the player directly, the player will survive probably with no shields. This effect varies as some players have reported surviving up to two shots from the laser.
 * If you find the unknown skull on Cortana and carry it through the rest of the level, you will start with a Spartan Laser in the next level.
 * It is one of only 3 infantry weapons capable of killing an opponent with a direct hit who has a fully charged (2x) Overshield. The other two being the Rocket Launcher and Missile Pod, however the laser is still much more powerful. This makes this weapon a popular choice for removing VIPs in the VIP gametype. The Sniper Rifle, Beam Rifle, and Fuel Rod Cannon do not have this lethality or power. With 3x or 4x overshield each of the three mentioned require 2 direct hits.
 * When wielding the Spartan Laser, if you look towards the barrel, there are two stickers/labels. One is a yellow triangle with unreadable text and the other is an unknown symbol. For reasons unknown, you cannot see these when it is on the ground or in Theater, only when you are holding it.
 * When the M6 is given to a Marine ally, they sometimes initiate the reload animation for the Rocket Launcher.
 * With the IWHBYD skull and on Legendary, Grunts will sometimes wield it and they sometimes say "My Arm Go Bye-Bye!"
 * If you give a Marine in the passenger seat of a Warthog a Spartan Laser, when the marine fires the weapon the angle of the laser is different to that which the Marine is aiming. This can be done on the Halo 3 Campaign level The Covenant.
 * The splash damage of the Spartan Laser does not injure opponents who are three or more meters away. It takes two to one meter distant impact to kill an opponent with no shields, for an opponent with normal shields and 9 for an opponent with 2x overshield (if the opponent is oblivious enough to stay still for that long and you have infinite ammo).
 * It actually fires multiple beams. It might be possibly that the design concentrate the beams into one single beam, and a glitch seperate the beams again.
 * The Spartan Laser is comparable to the Gears of War version, the Hammer of Dawn, but only in power not in the way the system works.
 * The Spartan Laser does not act like a true laser. A real laser is invisible to the naked eye, has no recoil, travels at the speed of light, and does not have "splash" damage.  These are all attributes the Spartan Laser does not exhibit.
 * The best weapon for CTF or Slayer game variants is indisputably the Spartan Laser, as it it can be used to constantly murder the Flag Carrier and opposing forces with a recurring makeup.
 * On Valhalla and other maps the Spartan laser can sometimes shoot though trees or rocks.
 * The laser beam can be moved around while firing, something like the Sentinel Beam. However, the Spartan Laser does not maintain its beam for more than several milliseconds, making this movement extremely difficult to pull off.
 * It is possible to kill both the driver and the gunner of a Wraith with a single shot on Legendary difficulty. The Wraith will be damaged but fully functional. To do this, one must target the cockpit at a certain point. On lower difficulty the Wraith may be completely destroyed by doing this.
