SCAR

Although called the SCAR in-game, the weapon used by Marines and the player is actually a Heckler & Koch XM8. The assault rifle can be customised in-game. You can attach either a reflex sight, assault scope or a sniper scope for sights. You can also attach either a light or rifle Laser Aiming Module for targeting purposes. Another nifty feature is the ability to attach either a tranquiliser launcher or a grenade launcher. Finally, you can attach a flash and sound suppressor to the weapon.

FY-71

The FY-71 is the main weapon for the North Korean soldiers in-game. It is actually based on the AK-74M. Like the SCAR, it features the ability to be customised. For scopes and sights, you can either attach a Reflex Sight, an Assault Scope or a Sniper Scope. For lights and lasers, you can attach a rifle flashlight or a Laser Aiming Module. In addition to that, you can attach a grenade launcher or tranquiliser attachment. Then, there is the silencer. One very useful thing about the FY-71 is that you can choose between normal ammo or inciendary ammo, once you get it.

MPX8

The MPX8 is the main weapon for North Korean forest patrols. It closely resembles an MP7A1 albeit somewhat longer. The MPX8 can also be seen in the hands of some North Korean nanosuit soldiers. The MPX8 is similar to the other weapons in the feature that it can be customised. You can attach all the attachments on the rifles except for the launchers. It also sports full auto and semi-auto fire.

DSG1

As the name implies, it's based on the DSR-1.
