- "Someone get on that turret!"
- — Dominic Santiago, to his fellow Gears, aboard the Derrick in Tip of the Spear
The Chain Gun was a large, high-caliber, electrically-cycled, fully automatic heavy gatling gun employed by the Coalition of Ordered Governments military. It was usually mounted on vehicles as an offensive weapon, such as on the King Raven, the Assault Derrick, and was seen on the Tyro Pillar. It could also be used as a stationary emplacement gun on fortifications for defense. It employed the Gatling-gun principle, in which six revolving barrels rotate around the firing axis. This arrangement allowed the individual barrels to cool between shots.
The Chain Gun's action was driven by an electric motor, unlike the hand-crank system of the Mulcher. This feeds ammunition and rotates the firing mechanism. As it rotates, the barrels close into the bolt for firing, then withdraw to extract the spent cartridge case and feed in a fresh round. The entire process happens very quickly; when the Chain Gun was fired, the sounds of the individual shots blured into a continuous, rippling roar.
Much of the Chain Gun's length was in its barrels; the actual firing mechanism is quite compact for such a powerful weapon. The weapon only had rudimentary iron sights; the gunner is expected to observe the stream of fire's fall and adjust their aim accordingly. To keep up with the Chain Gun's voracious appetite for ammunition, it was normally fed from enormous ammunition boxes, with ammo fed to the weapon via a flexible metal chute.
Because of the Gun's size and mass, it was far too big to be moved about by any one soldier. Instead, it was normally seen as a vehicular or aircraft weapon - it was particularly well-suited for being a helicopter door gun, its high rate of fire making up for the relative lack of accuracy that came from using a flying helicopter as a firing platform. It was also sometimes seen mounted on a tripod or base for use as a powerful defense weapon.
The Chain Gun was the COG answer to the Locust Troika. Though it's not quite as powerful as its Locust contemporary, it was still an incredibly powerful weapon that could tear even the most brutal of enemies to shreds.
In general, the Chain Gun is functionally identical to the Troika. It isn't as powerful (since it fires fewer bullets), but it's considerably more accurate. Like the Troika. Like the Troika and Mulcher both, it uses a cooling system that can flush the weapon with coolant should it overheat. Note that because the Chain Gun, like the Troika, is electrically-operated, its clutch stops the barrels cold if you stop firing to flush the gun with coolant. Because of this, it's advised that if you must stop firing, completely reduce the gun's heat before starting it back up.
In the Last stages of the Lightmass offensive, Marcus Fenix uses a Chain Gun mounted on the roof of the Tyro Pillar. He uses it to fend off attacking Reavers. It is then used by Dominic Santiago in the battle with the notorious General RAAM before the general killed by Fenix
Operation: Hollow StormEdit
During Operation: Hollow Storm, Chain Guns are mounted on the Grindlift Derricks. On board Delta Squad's Derrick (Rig 314), Sgt. Fenix used the turret to shoot down the attacking Nemacyst and scores of Reavers. Further along the road to Landown, the turrets on the derricks were used to fend of attacking Grapplers and even a Brumak.
Chain Gun's are used again during the Locust Siege of Jacinto, where Dominic Santiago and Marcus Fenix use the weapon for repulsing the attack by a swarm of Reavers on the Comm Tower in Jacinto Plateau.
During the Savage Locust attack on Anvil Gate, the defending Gears used the turrets on the front wall to beat-back the attackers, however after the Locust overran the front gate. As the Locust got deeper into the Fort, the Gears opened up with two more turrets, the confined area of the courtyard made it easier for the defenders to destroy the enemy.
Behind the ScenesEdit
Though named the Chain Gun, this weapon is actually a Gatling type weapon. The difference between the two weapons is that a chain gun uses a single barrel and is chain-driven as opposed to operated by recoil or gas blowback. A Gatling gun, on the other hand, uses multiple barrels which revolve as the weapon fires, similar to the way a revolver's cylinder rotates as it is fired. A Gatling gun may be operated by any number of mechanisms, from electric motors to gas systems to simple hand cranks, and use relatively complex timing to ensure that each barrel and breech fires, loads ammunition, and ejects spent casings at precisely the right moment.
In the terms of functionality, the Chain Gun is very similar to the Dillion M134 Minigun, which serves a similar purpose as a helicopter door gun, vehicle-mounted weapon, and emplaced defensive weapon, for use against most soft targets [i.e.: infantry] and lightly armored or unarmored vehicles.
- In Gears of War 3, Horde 2.0, it is unknown why the Cogs use Troikas since they are Locust weaponry and not the Chain Gun since it is Cog weaponry.
