M41A Pulse Rifle



The M41A Pulse Rifle uses electrically-fired 10x24-mm explosive-tipped caseless ammunition, which can be selected to fire semi-automatically, in four-round bursts, or fully automatically. An underslung, hand-loaded, 30-mm pump action grenade launcher features a four-round magazine.

The compact ammunition magazine holds 99 rounds, though is usually loaded with 95 to avoid jamming. An LED counter display located just below the receiver indicates the amount of remaining ammunition.

The M41 is constructed from lightweight, impact resistant composite materials, and weighs 10.8 pounds fully loaded. With shoulder stock extended, it measures 33.01 inches in length. Fully automatic rate-of-fire is 900 RPM, or 700 RPM effectively. By 2179, this weapon was the primary longarm of the USCM infantry.





M4A3 9mm Pistol



This medium-sized 9 mm pistol used exclusively by the USCMC is well known for its high capacity and light recoil. The M4A3 is the standard sidearm for all serving Marines, mainly used against human targets or aliens without a hard exoskeletal armor.

This is the handgun Vasquez used at point-blank range against the Alien inside the air vent.

The range is approximately 1500 meters, but its maximum effective range is 50 meters. It is rarely used against a xenomorph threat.





VP70 9mm Pistol



The VP70 PREDATOR by Ventrel is a 9mm semi automatic sidearm crafted entirely of composite materials making it light, rugged and dependable. Originally created from 150 separate parts, this has been reduced to 6.  The main feature of the PREDATOR is the simplicity. With a safety latch built into the trigger and a concealed hammer, the VP 70 has an extremely low chance of jamming or misfiring, even under high levels of heat and pressure.

The VP 70 can fire after 72 hours at 700 degrees and a combined weight of 7 atmospheres.  The VP 70 contains an insulated magazine that will prevent ammunition 'cook off' at temperatures up to 500 degrees.
The PREDATOR holds 11 rounds of 9mm ammunition with 1 in the chamber, and accepts both Military combat effective munitions and civilian shells.

In the years since the introduction of the original design, the VP70 has undergone little in the way of substantive change. More commonly, new, lighter, stronger plastics and alloys have gone into the pistol's parts, providing an even more reliable and more compact sidearm.





M42A Scope Rifle



The M42A Scope Rifle the primary sniper rifle for the USCM.

It uses the same 10mm case less, explosive tipped ammunition as the M41A Pulse Rifle, although the M42A has a slightly longer case for higher maximum range. These two formidable weapons share other characteristics. For instance, they both use the same electronic firing system and breach loading system.

The ammunition is held in a 15 round clip inserted into the stock just behind pistol grip. The standard round used in the M42A is the M252 HEAP (High Explosive Anti-Personal). This round has a maximum effective range of 2,250 meters over clear terrain. For even longer kill distances, a long-range stabilized ball round has been developed that can travel 3,800 meters.

The standard issue scope for the M42A is a combined, multi-spectral twenty power passive sensor scope. Images in the scope are based on input from visual, infrared, and electromagnetic emissions. Also, motion trackers, ground radar, lidar and IR sensors can input into the rifle through either digital comms broadcast or direct optical cable link.





M65A2 Smart Gun



For a Colonial Marine squad to survive engagement, it needs more than just rifles. Machine guns offer the Marines more firepower for offensive and defensive operations. The USCM picked the M56A2 Smart Gun as their machine gun of choice.

The M56A2 SMART GUN is a 10mm general-purpose automatic squad support weapon, effective out to 1500 meters. The pulse-action system employs a free-floating recoil-dampened rotating breech mechanism chambered for the M250 series 10mm x 28 caseless round. the gun also incorporates a muzzle booster to ensure the necessary operating forces from the large round. Cyclic rate is around 1200 rounds per minute.

The gun is constructed largely from molded carbon-fiber and light alloy stampings, though some interior parts of the mechanism are made from plastic. The replaceable barrel system is air-cooled, though a heat-sink attachment can be jacketed onto it. The system is mounted on an operator's harness and slaved to an infrared tracking system. As the name implies, the gun has 'smart' capabilities. Specifically, the M56A2 can aim itself. Using a targets infrared signature, it will 'steer' itself to aim at the target. While the marine operating the gun still has control of where to aim, it's best to let the M56A2 do it's job. The gun will not fire by itself. It still requires the operator to pull the trigger.

The entire gun assembly masses 17.82 kg. The length of the gun itself is 122 cm, and the length of the barrel is 54.5 cm.

The stabilized articulation arm is attached to the left hip mounting and plugged in via coaxial cable to the processor and power outlets in the breastplate. The gun itself is clipped and secured on the end of an free moving 'steady-cam' type harness with an articulating arm. This gives the gun a wide range of motion and targeting area. The actual weight of the gun is supported by the operator's shoulders and legs, allowing it to be used for extended periods of time with less fatigue.

The operator plugs this HMS (head mounted sight) into the tracking and comms system in the armor. the gun tracker is jacked into the process by a universal connector, and the gun itself must be powered up before the weapon is loaded. Power for the entire gun system is supplied by standard DV9 Lithium battery units, good for up to 50,000 rounds when fully charged. Both ends of the DV9 unit are plugged into the power leads that run from the articulation arm to the gun; common practice in the field is to let the battery hand free beneath the gun, where it is easily accessed in an emergency.

The M250 10mm x 28 ammunition is a 230 grain caseless projectile encased in a rectangular block of Nitramine. Higher powered that the M309 round for the pulse rifle, the M250 also significantly differs in having a selectable fuse setting. A switch on the hand grip is used to select the ammunition fusing, which is set electronically as the round is loaded into the chamber. The 'Super' setting is optimized against soft targets and will detonate the round on impact, while the 'Delay' setting explodes the shell only after penetrating the target armor.

The M250 ammunition is stored on a roll of continuous plastic non-disintegrating link belt in the ammunition drum, which can be reloaded in the field. The gun motor drives the feed mechanism as well as the rotating breech, and automatically loads each round off the belt and into the breech. In the event of a jam, the manual cocking handle at the side can be pulled to eject the round and clear the breech. This procedure can also be used to manually charge the mechanism. This will keep jams to a minimum.





M240A1 Flamethrower



The M240A1 Flamethrower is a simple mechanism made by Roderickson Enterprises. It is a lightweight, carbon-format Flamethrower designed for use in close combat at the squad and firearm level. Using pressurized, ultra-thickened napthal fuel as a base and ignited by the nozzle burner, the M240 can shoot flames with a steady 300 degrees Celsius at targets up to 30 meters away.

With sufficient fuel in a standard fuel reservoir for a burst of up o twenty seconds, the M240 is undoubtedly one of the most fearsome weapons in the Marine inventory, and has proven especially useful in close combat and against the Xenomorph, because of the fact that it roast the acid before it reaches the weaponoperator. It is also ideal for use against fortifications because of the ability of the flame to be directed through defensive apertures. However, it is unpopular with many of its operators, partly because of its short range, and also because of the tendency of the fuel reservoir to rupture violently when hit by shrapnel or small arms fire. Aditional to that, if the operator turns the gas pressure too low, the flame could manage to travel back into the flame thrower, and explode one hell of a big explosion. (Safety systems were never bothered to be put in.)

The M240 is 88cm long and weighs 2.7 kg with a full reservoir. A valve at the rear of the incinerator is used to refuel the weapon; alternatively, the reservoir can be screwed off and refilled or replaced separately. A twist-valve on the Flamethrower regulates the fuel flow and a thumb switch on the handgrip electrically ignites the nozzle burner when depressed. The weapon is fired by squeezing the handgrip trigger, and will continue firing until the trigger is released. The range of the M240 can be increased by making a high angle show, firing the flame unit up at an angle of about 45 degrees – the burning fuel then descends onto the target in an arc. In this way shots can be made up to a range of 50 meters, though it is far less effective then direct fire in penetrating an armored firing slit or aperture.





G-5707 Combat Knife



The combat knife is an often over looked standard issue weapon of the USCM. In this age of lasers and kinetic energy weapons, many don't think the knife as being important. The Colonial Marines know differently. Close combat knife fighting is still taught during boot camp and is a regular part of every day training. When silence is key, nothing is quieter than a knife.

Though the knife may seem primitive, the M142 and M144 combat knifes used by the USCM are very high-tech. Each one has a composite handle and a precision cut, long lasting diamond coated titanium blade. The diamond coating keeps the blade finely honed with no sharpening. The blade is so sharp that, with enough pressure, it can puncture Class 2 personal body armor.
