The M56 Smartgun system actually consists of four major components — the operator's combat harness, the head mounted sight, the articulator arm and the gun itself.
The M56 is carried into combat on a self-aiming stabilized mount that is linked to an infrared target tracking system for accurate, autonomous aiming. The mount also negates the traditional need to position or set up the machine gun prior to opening fire. The gun itself is constructed largely from moulded carbon fibre and light alloy stampings, though some interior parts are made of high-strength plastics. The weapon is air-cooled, although an additional heat sink attachment can be mounted to further improve sustained fire capabilities. The M56 is 122 cm long, incorporating a 54.5 cm barrel, while the entire gun assembly, including the harness and a full load of ammunition, masses 17.82 kg.
Unusually, the M56 incorporates two different firing mechanisms in its design — firing is controlled either by depressing a red "fire" button mounted on the forward hand grip, or by lifting a firing handle mounted beneath the rear grip. A selector on the forward grip switches the weapon between its Safe, Burst and Autofire settings. The Burst setting will fire four-round bursts, while the Autofire setting will continue to fire the weapon at its full cyclic rate so long as either of the triggers remains depressed. Clicking off the safety will also automatically charge the weapon (provided there is not already a round chambered), although Marines have expressed disdain for this system, citing it as a major cause of stoppages, and prefer instead to manually charge the weapon after reloading using the cocking handle on the right side.
The gun's rotating breech and feed mechanism are powered by an internal motor. In the event of a stoppage, the charging handle can be used to clear the mechanism. Smartgun ammunition is stored on a roll of continuous plastic non-disintegrating link belt; the drum magazine on the M56 typically holds 150 rounds and can be quickly reloaded in the field.
While the operator is standing, the gun is held and steered by its fore and back grips. The gun can also be fired from a prone position, although owning the weapon's unique design, this entails the operator lying on their back. When prone, the gun is controlled with the foregrip and the charging handle, the latter of which must be locked forwards for this purpose.
Operator's harness and mountEdit
The M56 is mounted on a harness and is slaved to an advanced infrared tracking system, similar to that found in the USCM's UA 571-C Automated Sentry Gun. The battle harness worn by the operator is manufactured from the same composite micromesh ballistic armor as the Marine Corps' standard M3 Pattern Personal Armor. The chest piece contains the Smartgun operator's PRC 489/4 communications transmitter/receiver and Identification Friend Foe (IFF) transponder, as well as the gun's tracking and targeting processor. The processor is accessed from behind the chest plate, and can be easily replaced in the field should the unit fail.
The M56 is securely attached to the operator by a stabilized articulation arm, attached to the left hip and connected via a coaxial cable the to processors and power outlets on the chest plate. The system's head mounted sight is also connected to the tracking and communications systems in the chest plate. Power for the entire system is supplied by a standard DV9 lithium battery, plugged into the power leads that run from the articulation arm to the gun; removing this unit completely deactivates the weapon, rendering it useless. Common practice in the field is to let the battery hang free beneath the gun where it can be easily accessed in an emergency.
The gun itself is self-steering on its mount, although firing must be triggered manually. The articulation arm is gyrostabilized and provides additional recoil dampening, and is also capable of keeping the gun steady while the operator is walking or running. When tracking a target, the arm steers the gun so as to aim the barrel at the target's center of mass. Working fluidly with this automatic tracking takes some training to master; the operator must be sensitive to the gun's movements and allow it to aim itself, although the weapon's motion can be overridden at any time by simply steering the barrel elsewhere.
When powered up, the gun begins tracking targets via the infrared detector mounted directly above the barrel. This scanner consists of a 256×256 element platinum-silicide focal plane array, cooled to 77°K (-196.15°C) by a tiny cryogenic gas cooler. The system monitors a 30° cone in front of the gun. The tracking system also transmits thermal images to a miniature video display in the operator's eyepiece. If a target is detected, the tracker will overlay a lighted box or rectangle over the target's center mass on this display, highlighting it for the operator's attention. At the same time, the articulator arm will steer the gun towards the target, and once it has acquired a lock the operator will be informed by a target lock circle that illuminates on the display screen.
In the event that the operator wishes to engage an opponent other than the one currently locked on to, they can simply steer the gun manually towards their preferred target and the system will acquire a fresh lock. This tactic is also vital when faced with the use of infrared false-target decoys.
- Main article: 10×28mm Caseless
The M56 Smartgun is chambered for the M250 10×28mm High Explosive Armor Piercing caseless round, a 230 grain projectile encased in a rectangular block of Nitramine 50. This round offers greater power than the M309 used by the M41A Pulse Rifle, and also offers a selectable fuse setting — a switch on the Smartgun's grip is used to switch between ammunition fusing modes, and the setting is applied to each round electronically as it is loaded into the chamber. The Super setting is optimized for use against soft targets, detonating on impact, while the Delay setting will allow the round to penetrate armor before exploding.
As per USCMC doctrine, USCM's are organized into rifle squads at the lowest levels of organization. One element of this squad is the Gun Team. The Gun Team is made up of a rifleman with a M41A Pulse Rifle and a machine-gunner carrying the M56 Smartgun. The rifleman provides spotting and defense support for the machine-gunner, who in turn provides fire support for the rest of the rifle squad.
The M57 is the 'sequel' to the M56 smart gun used for the better part of the last two decades. Unlike the M56 the M57's gun barrel does not autonomously track targets; instead the gun coordinates multiple guided projectiles. This increases fire rate significantly, reduces operator combat fatigue, and sidesteps lengthy training requirements. It also means that an M57 round can dynamically retarget mid-flight, should the firing M57 determine that the round’s initial target has already been defeated.
M57D "Dirty" SmartgunEdit
The M57D is an utterly vicious weapon that is sanctioned for extreme circumstances only. It fires rounds that shatter into hundreds of radioactive splinters inside their target, causing human survivors of the weapon to develop all manner of debilitating long-term health problems. It can create truly astounding radiation levels in larger targets, forcing these enemies to lose health for extended periods of time. Naturally, the upgraded Smartgunner wears radiation shielded armor as a safety precaution.
In use with the USCM by the time of the incident on BG-386, the M59/B is fairly similar to the original M56, although it features an upgraded scope that will highlight all recognized threats in the weapon's field of fire; as with the M42C Scoped Rifle, these highlighted targets will be visible even through walls and other obstructions at close range. The weapon will also lock its barrel in place when automatic tracking is switched off, allowing for rounds to be fired at a greater velocity. While this allows for greater damage output, the drawback is that the weapon requires manual aim when in this mode.
Behind the ScenesEdit
The M56 Smartguns in Aliens were based on concept sketches drawn by director James Cameron, although much of the final design was created by British movie armorers Bapty & Co., who built the live-firing weapons. The Smartguns were based on WWII-vintage German MG 42 belt fed machine guns. The guns were disguised with cosmetic additions, including parts from a Kawasaki GT motorcycle; the rear "trigger" is the motorcycle's clutch lever and the front barrel dressing was derived from the bike's suspension, while the forward grip was the Kawasaki's throttle handle. The weapon's muzzle was also extended with a custom brake added to disguise the MG 42's distinctive bulbous muzzle. The additions were designed to give the machine gun a unique appearance whilst remaining reminiscent of real-world weaponry.
The prop itself is over 50 inches long. Due to the construction being primarily of metal, the weapon's significant weight created its own set of problems during filming. The weapons were also very unwieldy, and as a result were physically attached to the actors using a steadicam filming harness, transferring most of the gun's considerable weight to the actors' legs while also helping to balance the weapon. Even so, the Smartguns required careful handling by the actors at all times; at one point, Jenette Goldstein took her hands off of her weapon and, according to chief armorer Simon Atherton, it "shot out in front of her and she toppled over and landed smack on the floor".
In the film, the M56 was used by Vasquez and Drake, who had customized their weapons with the words "ADIOS" (on Vasquez's Smartgun) and "My bitch" (on Drake's) written on the side ahead of the charging handle.
At least one of the props from the film (the one owned by the Prop Store) had the markings "ADIOS" and "bitch" on the side, one painted over the other. This is an indication that these guns were interchanged between the characters while filming, a fairly common movie practice. The same prop owned by the Prop Store has been deactivated to comply with UK law and has had some restoration to bring it back to its original condition.
- The M56's tracking mechanisms are said to be infrared in nature. However, in Aliens, the Xenomorphs are shown to be invisible to infrared scanning (similarly, Yautja are unable to detect them with their heat-based vision mode). The Smartgun should therefore be unable to track the creatures. Whilst Aliens makes it seem as though this is indeed the case — Vasquez and Drake are seen spraying wildly with the weapons whilst inside the Hive, instead of firing targeted bursts as would be expected — numerous video games portray the Smartgun as being able to track Xenomorphs with ease, which would be incorrect given what we know.
- As well as the standard M56, Vasquez's Smartgun from Aliens is featured in the video game Aliens: Colonial Marines as a "Legendary Weapon".
- The HUD of the M56 Smartgun in Aliens: Colonial Marines is very different from what was seen in the Colonial Marines Technical Manual, with the HUD seen in the manual being much simpler.
- In the Brady Games Aliens: Colonial Marines Guide the Vasquez's Smartgun section name and description use "Smartgun", despite the M56 Smartgun section and description using "Smart Gun" and the game itself using "Smart Gun" for Vasquez's M56 and the standard one.
- The G.I. Joe Pursuit of Cobra 'City Strike" Iron Grenadier and 30th Anniversary Iron Grenadier figures come with a "Thermo-reactive anti-armor assault cannon" which appears to be heavily based on the M56 Smartgun. The assault cannon uses cased rounds (like the actual prop used in Aliens) carried in an ammo box held on the bottom of the cannon or on the figure's back. The front of the packaging of both figures depicts the Iron Grenadier wielding his cannon (although only a small portion of the Iron Grenadier and cannon are shown) and the back of the 30th Anniversary figure depicts the full Iron Grenadier wielding his weapon.
- Similarly, the G.I. Joe Pursuit of Cobra "Desert Battle" Conrad "Duke" Hauser figure comes with a rifle which appears to be heavily based on the M41A design.
- The GI Joe Convention 2013 Night Force Repeater figure also featured a weapon which appears to be heavily based on the M56. The figure's card mentions that he is a "STEADI-CAM MACHINE GUNNER" indicating that the machine gun is actually supposed to be mounted on a steadi-cam as with the M56 prop used in Aliens. The weapon's sculpt is very similar (if not the same) as the Iron Grenadier's (although this one is intended to be attached to a mount) and also uses cased rounds carried an ammo box which is can be held in the same positions as the Grenadier's.
