A/N: This is the UNSC Infantry weapons for Marines up to SPARTANs. Most of the weapons are the same build to those in the game but with more options available to the user. If you want to I'll see if I can make an Entry for UNSC Armour Armaments (Tank Guns, before you're confused). They'll be a direct reference to a weapon skin change in Halo 5 that I personally prefer. Internet Cookies if you're correct!

Designed and Built, then handed over to legendary Snipers like Linda-058, Jun-A266 to modify and tweak with the weapon whist testing it for any flaws and imperfections that they see. The Manufacturers then met them to note what they can implement into the design, making the specialist words of both snipers, standard. The weapon uses a range of ammunition similar to those found on other firearms, however, just at a much larger caliber of 25mm Rounds. This has led to many different nicknames for the weapon.

Weapon History: The M779 SAW LMG was the replacement to the M739 SAW. Built for the UNSC, the M779 SAW uses the same calibre round as the Designated Marksman Rifle, however, whereas the DMR is a precise weapon, the M779 is more of a wall of High-Calber shots to dissuade enemy troops from advancing or exposing their bodies to return fire. When questioned why they'd use the same round as an DMR, the Manufacturers stated examples of where a heavily shielded enemies, For Example, Zealots and Field-Marshalls, the previously tested rounds had such little effect, they'd need 379 rounds to crack the shields and neutralise the target. Thus the 13.7 x 62mm round was implemented into the design.

Rate of Fire: 1,000RPM

Weight: LBS (KG)

Length: 84.76IN (215.3CM)
Width: IN (CM)
Height: IN (CM)

Weapon History: The M267K Heavy Machine Gun is a single barrel, Hybrid Water/Air-Cooled, 1-Operator Support weapon. Built to replace the ageing M247H and AIE-486 Heavy Machine Guns, the weapon is the combination of a High Rounds Per Minute and Heavy Damage Per Shot to eliminate heavily Armoured and/or Shielded opponents quickly. Preliminary designs were rejected based upon the Gatling Gun design, due to test showing the barrels glow red hot after a minute of sustained fire. Designs were also changed based upon lessons from the Human-Covenant War, with encounters with Mgalekgolo (Hunter) Pairs, the need of making such enemies think twice about charging in front of these. So the designs that were originally calling for a .50 Calibre HMG, would be a receiving 20mm Heavy Machine Gun instead. Such a change was debated heavily with High Brass, though Marines and frontline troopers were happy with it, giving them the power to disable Light Armoured Vehicles and Aircraft too.

Weapon History: The M50 Tactical Assault Shotgun is the replacement of the ageing M45 Tactical Shotgun Series. Designed and built to smash enemy shields and armour at close range with the same shot being the only fired. The weapon was bored to fire a 4-Gauge Shell instead of the usual 8-Gauge shell that previous Tactical Shotguns used. Due to the larger round, more strength was put into the structure of the weapon, allowing a SPARTAN-II to use it as a club, whilst still maintaining the ability to discharge correctly and properly.

Weapon History: The M27/Caseless Submachine Gun was built to be like the its predecessor, a bullet hose. Not much was changed aesthetically, however, the weapon fires a larger 9mm round, the ability to accept two magazines on either side of the PDWS and the addition of the Rail attachment system. The weapon is the standard-issue sidearm to all UNSC Forces, however, ODST's and SPARTAN's tend to use another primary weapon or the venerable M6R (Utilises the Top and Flank Rails) as their secondary weapon, but its not uncommon to see one or two M9 PDWS's on the thigh plates of individual Marines, ODST's and SPARTAN soldiers.

Length: 66.34IN (168.5CM)
Width: 15.1IN (38.3CM)
Height: 21.5IN (54.5CM)

Weapon History: The M52 Medium Anti-Vehicle/Assault Weapon Missile Launcher was designed for an up-to-date Anti-Vehicle system with infantry elements in the field without Armour or Aerial Assets to aid them. Prior to 2557, M41 SSM "Jackhammer" Rocket Launchers were based upon a double tube system, which rotated a fresh tube into place when fired. This feature allowed the rockets to be fired at near simultaneous times where each rocket would turn away and attack from two angles. That feature was built into the M52 Missile Launcher and an experienced operator could either lock-on specific points of the vehicle, or lock-on up to six separate targets at once. Coupled with the 145 x 82mm Smart Missile and a number of different Warheads, this system could devastate an enemy vehicle advance, whether it's an Aerial Assault or Armoured Ground Assault, with no adjustments to the weapon.

A/N: Thank you for reading this Codex Entry. This does actively tie in with my crossover of Warhammer 40,000 and Halo. The 3rd Chapter is halfway finished, but I am trying to make sure that the Space Marines and UNSC communicate correctly without Warhammer fans flaming me for my "lack" of knowledge in said department. I will try to get two more chapters out before the end of 2015.
