Special Weapon Operation Reactional Deployment System

The , also known as SWORDS or the SWORD, is a UNSC Weapon modification system. Using Misriah Rails mounted on firearms, every UNSC operator can modify his weapon to match the needs of the current conflict or situation. This allows a simple assault rifle to vary between a close quarters assault rifle to a designated marksman rifle or grenade launcher. Most firearms have a 'set' equipment list, and anything else must be requested through the armoury. While the UNSC issues the vast majority of gear, many more modifications can be bought for 3rd party manufacturers for very specific performance properties. 
==Modifications==
===Sights===
====Long Distance Sights (6x-20x)====
*M75 AUGUR Scope (AN/PVS-75): The AUGUR Scope is the computerized, hand built scope popular with sniper rifles. It was created from information learned from previous ORACLE and HYPERION precision systems. The AUGUR consists of a primary digital sight and a secondary exotic sight/fire control unit. It measures telemetry, including velocity and range, along with bullet drop, wind, ambient air density and Coriolis factors to designate the best possible shot. All Augur type scopes come with motorized scope covers. Along with that it can wireless feed into the user's HUD or UNSC War Net to collect UAV/GV, aerial and Satellite Recon or connected to a exterior system by one of it's three Hard Line ports. The bullet telemetry can be modified for the weapon in use and disabled if necessary. It can preform optical enhancement for weather, allowing it to pierce heavy rain, snow and fog, with UV and multi-phase night vision vision enhancements (It scans in two stage passive infra-red and active infra-red with three viewing modes including night vision, infra-red and active fusion that provides passive illumination and active thermal identification of high heat targets.), though only to a 5x zoom, a mid-ranged terahertz wave sensor that allows for vision through solid objects and anti-electronic assistance which allows it to lift optical screens and electronic interference. Along with that, it projects ammunition type and capacity, along with the capability to arm and direct self-guiding and self-arming warheads. The main computerised sight features a range finding/day and night all weather designator LASER, Neutron Detector, a CPU driven logic system, which monitors the War Net and local meteorological conditions, a polarised, none reflective lens, making it useful for the operator in high light conditions and giving it low observability. It's last feature is variable zoom settings ranging from 1 to 2, 4, 6, 8, 10 and 20 x digital zoom, providing a clear image even at those ranges. It can be directly hard wired into the user's helmet via a optical cable, or linked wirelessly. It has manual adjustable light setting and replaceable batteries. (SRS-99)
*M16 Long-range Electronic Sight: The LORES is electronic, long ranged sight, with an adjustable 8x zoom for targeting more distance enemies with precision. It has two hard line interfaces, a wireless uplink, night vision capability and an inbuilt ammo counter than links to the on-board weapon systems. Less sophisticated but more robust than the Augur sight, the LORES is often used on designated marksman rifles, or snipers in urban combat, or other operations where range is expected to be short.
*M403 Telescopic Sight: A simplistic sight, utilising 6x telescopic sighting, it is used by snipers and marksman for combat scenarios where complex sights reliant upon electronics may be found undesirable. It can be modified on the fly for varying conditions, with dials for magnification, focus, elevation, windage, parallax compensation and illumination. 
*M9Z Precision Rifle Sight: The PRS, better known as the Sentinel sight, is an electronically assisted rifle sight preferred for mid to long range engagements. The sight has a ballistic firing computer, adjusting for environmental and meteorological conditions, and connecting to the user's HUD. Robust, but on the larger side, the Sentinel is preferred for Designated Marksmen. It also features a range finder, and an ammo counter. 
*M101X Exotic Combat Scope (AN/PVQ-101X): The ECS is a scope using a high-power terahertz wave sensor to allow it to see through solid objects, such as walls. It comes with a variable six times zoom ability, wireless interlinking, two hard line ports and replaceable batteries.
====Mid range sights (2x-4x)====

==Barrel Modifications==
Most UNSC firearms are fitted with threaded barrels, which can change the fore-end. Usually fitted with a manufacturer made flash suppressor, these can be changed for a variety of other systems. 
*Flash Suppressor: A standardised item, most flash suppressors vary from weapon to weapon, but all share in common their capability to reduce the flash typically associated with firearm discharge. 
*Suppressor: Most UNSC weapons are compatible with issued suppressors. These devices reduces the noise and flash of a weapon. These Suppressors are fitted with adjustable gas bleeders from the barrel, preventing the rounds from reaching supersonic velocities which avoids the need for specialized subsonic ammo. They are designed as 'quick attach', fitting over the flash suppressor and can be quickly attached or detached.
*Muzzle Break: An unusual item, it is usually fitted in rare instances to high calibre rifles, such as the M1091 SRS, M396 DMR or MA6B ICWS. The muzzle break is designed to reduce the recoil associated with high power rounds, allowing them to provide continuous fire without the associated recoil.
*Breaching Barrel: A barrel for shotguns, it is designed similarly to a muzzle break, and disperses hot gases to the side, rather than forward, to prevent them being deflected back at the shooter.
==Others==
*Tripod: Several heavy weapons can be mounted on stabilised and adjustable Bipods that feature shock absorbing and adjustable legs allowing them to be positioned at near ground level to a full standing position. The feet can be bolted down into any material it is mounted on and feature a load bearing weapon mount that can be rotated across all axis.
==Third Party Modifications==
The list of third parties offering modifications for UNSC weapons is quite extensive, making it easier to divide them by manufacturer.
