Back to U.S. Colonial Marines

The United States Colonial Marine Corps is America's interstellar force-in-readiness. The USCM is America's only major means to forcibly enter a hostile area from space.

Armoury

Body Armour

The marine combat armour is designed to balance lightness and comfort with the utmost protection. The outer layer of the armour is an ultra light titanium aluminide alloy to provide structural strength and ablative protection from lasers. Beneath this is a core of boron carbide, an incredibly hard ceramic designed to shatter a bullet on impact while simultaneously forming a conoid base to absorb the energy of the bullet. Beneath this is the carbon fiber layer that provides ballistic protection by delaminating across a large area. Finally, on the inside of the armour is a liner made of 1500 denier Venlar fibers. This woven liner dissipates the remainder of the energy by deforming in the area of the impact. It is also capable of catching any spalling or fragmentation from the first three layers.

The M3 armour comes in different pieces, the main component is a rigid vest that protects the upper-half region, both front and back, and between the groin and neck. This has a two piece clamshell secured at the sides by plastic clips. The two segmented pieces are attached by the webbing straps to protect the sides and front and back of the shoulders. Inside of this clamshells are remote biomonitors which measure the marines life signs which include heart-rate and breathing. An optical cable connects this to the PRC 489/4 transmitter in the M10 helmet.

On the rear left of the shoulder of the armoured vest is a mounting bracket for a high powered halogen white light TNR lamp. The lamp runs off of a rechargeable internal battery and has a handle so that it can be detached and used as a hand torch. Also on the back of the armour are three mounting brackets that can be used for an Individual Marine Pack, a lightweight medium sized pack designed to carry up to 24 kg. It is attached also to a carbon fiber frame which clips to the rear of the armour mount. The pack is water repellent but not waterproofed, but there are waterproof liners that are issued for each of the main compartments and pockets.

ZX Shotgun

The ZX is a 12 guage pump-action shotgun. Made solely of lightweight metal alloys, the ZX is as sturdy as it is dangerous. The weapon can hold a maximum of 12 shots which are contained in the bulky magazine located in the base below the round chamber. The fact the ZX takes a magazine reduces manual reload time.

The rounds themselves are specialised. Instead of the buck-shot round typical of previous models, the ZX utilises the M10 rounds. The M10 rounds house approximately 20 smaller explosive projectiles, which have a minimum spread out of only a foot in diameter at 30 meters after the weapon is fired.

The ZX has an automatic spent cartridge discharger to free the firing breach for successive rounds.

STATISTICS

  • Muzzle Velocity: 355 m/s
  • Length: 87.6cm
  • Weight: 4.5kg
  • Maximum Range: 80m
  • Effective Range: 30m

M-41A Pulse Rifle

Type : M-41A Pulse Rifle 10mm with 30mm pump action grenade launcher and Digital Counter

Ammunition: 10mm explosive tip cassless standard light armour piercing round .M-40 Grenades

Capacity: 99 rounds

The M41A Pulse Rifle is the standard issue for all United States Colonial Marines. It fires a 10mm Explosive Tipped Caseless Light Armour Piercing round. The M41 uses electronic pulse action to fire, controlled directly from the trigger. The internal mechanism, including the rotating breech, is mounted on free-floating rails within a carbon-fiber jacket. This assembly is recoil dampened to reduce the effects of muzzle climb during burst and full automatic fire. From the thumb selector, the weapon can be set to selective, four-round burst, or full automatic fire, the latter allowing a rate of fire up to the weapon's cyclic rate of 900 rpm.

M56 Smart Gun

The core of a Colonial Marine squad's fighting power is its machine guns. More effective than a rifle, machine guns can sustain large columns of continuous fire both in the attack and defence, and are frequently the most decisive weapon in a firefight. The M56 Smart Gun is the Colonial Marines' primary squad machine gun. The M56 is carried with a self aiming stabiliser, and is linked to an infrared target tracking system.

The M56A2 is a 10mm general-purpose automatic squad support weapon, effective out to 1500 meters. The pulse-action system employs a free-floating recoil-dampened motorised rotating breech mechanism chambered for the M250 series 10 mm x28 caseless round. The replaceable barrel system is air-cooled. The system is mounted on an operator's harness and slaved to an infrared tracking system. The gun is self-steering on the mount, though firing must be commanded manually.

All firing is controlled from either the forward hand grip or the rear firing handle; the operator fires the weapon by depressing the red 'fire' switch or pulling the firing handle upwards. There are three setting on this switch; Safe, Burst and Autofire. The Burst setting will fire four round bursts, while the autofire feature will continue to fire the weapon at its full cyclic rate so long as the fire switch remains depressed. The M250 10mm x 28 ammunition is stored on a roll of continuous plastic non-disintegrating link belt in the ammunition drum, which can be reloaded in the field.

M240 Flame Unit

The M240 is in reality, a lightweight carbine-format flamethrower. It is designed to be solely used in close combat situations at the squads and fireteams level. The weapon uses a pressurised, ultra-thickened Napthal gel as a base and is ignited at the nozzle burner, and can be used to cover an area up to 25 meters. Once as the target is hit, the gel will adhere and continue to burn for up to one minute.

With a sufficient fuel in a standard fuel reservoir for up to 20 bursts, the flame-thrower is considered to be one of the most fierce weapons in the marines armoury, and has even been useful in close combat situations and as well as xenomorph exterminating operations. However, this weapon is one of the most unpopular with its operators, basically because of the fuel reservoirs tendency to rupture violently when hit by shrapnel or from small arms fire.

UA 571-C Remote Automated Sentry System

The UA 571-C Robot Sentry is an automated point defence system. It consists of a 7.62 mm machinegun mounted in an automated servo system with IR, motion and ambient light sensors for target acquisition. The entire package is armoured (SP 20, SDP 30) and mounted on a sturdy tripod (Leg SP 20, SDP 15). The weapon cannot be detached from its base or used by hand. Each weapon comes with a control terminal microwave-linked to its Sentry gun, which can be placed up to 1000 metres away from the Sentry.

The system is sophisticated and can be set to search based on a target's visual and/or thermal profile or 'auto-remote', using the system's built in IFF transponder and stutter-chipping, allowing it to avoid firing on a target wearing a personal data transmitter or M10 helmet IFF transponder with the right IFF code (this may be deactivated at the operator's command). Because the UA 571-C lacks a human's judgement, clearance of the ranking officer is required by law (although not needed) to use the system.
