The UNSC mounts a number of heavy weapons on their vehicles, giving them a wide range of tactical flexibility and firepower.
The M11 is a simple weapon, often deployed as a tripod mounted squad support/defensive weapon, that uses 25mm shells. It is gas operated and belt fed, drawing ammo in from an attached tin, drum or belt. Though less capable of the armor penetration possible with the 90mm AT gun on the Scorpion, or the M68 Gauss Gun found on the M12G1 LAAV, it does have effective light anti armor and anti infantry properties, being able to kill even shielded Covenant units in a shot. The M11 has a wide number of shells that provide extra versalitiy to an already effective gun: an HE Shell (used in anti infantry operations), an Incendiary Shell (used in anti infantry, anti vehicle (open) and anti infatry in wooded or forested area operations), an AP Shell (used in anti vehicle operations), a Sabot Discarding (used in anti vehicle operations), and an AP-HE Shell (a commonly used dual purpose shell)
M638 Automatic Cannon
The M638 Autocannon is a self-loading, 20mm chaingun. It is used as the nose gun on the D-77I Pelican and as two forward point defence guns on the Tortoise and the turret on the Whale and Dolphin landing vehicles.
M1024 Automatic Cannon
The M1024 Autocannon, also called the Misriah Gun, is a self-loading, 30mm chaingun. It is usually found on light and medium vehicles which is used in a anti-infantry or engaging light vehicles.
M309 Automatic Cannon
The M309 Autocannon is a self-loading, 40mm autocannon chaingun, used as a anti aircraft gun.
M891 Heavy Automatic Cannon
The M891 Automatic Cannon is a 70mm chaingun, the largest chaingun used by the UNSC.
Vehicle Mounted Machine Guns
The M780 MG is a multi-barrelled 6.8mm minigun that utilises caseless rounds.
The AIE-486I HMG is a 7.62mm multi-barrelled machine gun used to engage infantry, light armour and aircraft.
M41B Light Anti Aircraft Gun
The M41B LAAG is a improved version of the M41 LAAG, using a small plasma core battery over the previous hydrogen-electric battery. It can operate for longer, at higher speeds, meaning it has a higher rate of fire. It also has the setting for it to be set to whir up so it can be ready to fire when necessary. Using new metallurgic techniques the barrels can last for years without changing, allowing for near continuous fire.
The M247H2 HMG fires the same high power 12.7mm AP round as the M41 LAAG but lacks the rotary barrels to its rate of fire is lower. It is cooled by liquid coolants and has an advance barrel that does not need regular changing, allowing for continuous fire.
M68A2 Asynchronous Linear-Induction Motor
M68A2 Gauss Cannon is a improved version of the M68 of the Human-Covenant War. It uses a advance plasma core, frictionless barrel lining and cryogenic gas cooling system to maintain maximum operation power. It has a drum of 12 rounds in a rotary spring loader. It can operate for longer than the M68. It fires 25mm slugs. This was laer replaced by the M68B ALIM.
M76 Asynchronous Linear-Induction Motor
The M76 Gauss Gun uses 30mm slugs and a high velocity gun that greatly increases its armour penetration. It is loaded in clips of three slugs and it uses a advance plasma core, frictionless barrel lining and cryogenic gas cooling system to maintain maximum operation power. This was replaced by the M76A ALIM.
M85 Asynchronous Linear-Induction Motor
The M85 Gauss Gun uses 90mm slugs that greatly increases its armour penetration. It is capable of penetrating most tank armour and is breech loaded. It uses a advance plasma core, frictionless barrel lining and cryogenic gas cooling system to maintain maximum operation power. This was replaced by the M85A ALIM.
M94 Gauss Gun
The M94 Gauss Gun is a massive weapon mounted only on the Mako-class Frigate and the M1000 Tiger Heavy Battle Tank. The M94 is a breech loaded Gauss Gun that fires 120mm slugs capable of penetrating all but the very heaviest armor and fortification. It uses a advance plasma core, frictionless barrel lining and cryogenic gas cooling system to maintain maximum operation power. This was replaced by the M94A ALIM.
The M204 Railgun is a 10mm railgun used on some light aircraft as a close in weapon
The XM299 is a 10mm railgun with rapid fire capabilities that replaced the M204
XM300 30mm Railgun
The XM300 Railgun is a automatic 30mm railgun that replaced many 30mm autocannons in service
The M288 railgun is a 40mm railgun used as an anti-aircraft weapon
The XM301 is a 40mm automatic rail gun used on anti-aircraft vehicles.
M512 Smooth Bore High Velocity Cannon
The M512 Smooth Bore High Velocity Cannon 90mm cannon is the standard of the UNSC, with it being the primary cannon of the Scorpion MBT. It is a powerful smoothbore high velocity cannon.
M567 Smooth Bore High Velocity Cannon
The M567 SBHV Cannon is a enlarged and longer vesion of the 90mm cannon for anti tank duty.
M588 Smooth Bore High Velocity Cannon
The M588 SBHV Cannon is a 120mm gun that replaced the 105mm gun in service.
The M234 Howitzer is a 155mm Cannon that is used as an artillery gun, both standalone and on armoured chassis.
Special Vehicle Mounted Weapons
M579 Canister Gun
The Canister gun is a 150mm cannon utilising multi-purpose canister shells for a wide variety of purposes, against armour, infantry and buildings.
M689 Rocket Mortar
The Rocket mortar uses a 350mm rocket propelled mortar to cause severe damage against a single hardened obstacle or multiple exposed infantry units or light armour.
M45 Rotary Cannon
The M45 is a caseless 20mm, six barrelled automatic cannon used on a variety of vehicles and aircraft.
M701 Rotary Cannon
The M701 is a caseless 30mm, six barrelled automatic cannon used as both an anti-infantry and anti-armour weapon.
