GD Lightweight | medium machine gun
The GD-LWMMG (called the Chief Wiggum by New Hayesalian soldiers) was developed as a capability gap being experienced by New Hayesalian forces in the first Zellatian civil war. In many cases, troops were on low ground and being engaged by PKM machine gun fire from the high ground, forcing them to return fire from where they were instead of being able to seek a better position.
The M2 .50-caliber machine gun is too heavy for use by dismounted patrols, and rounds from an M240 begin to drift off target at 800 meters, especially when shooting upwards. At closer ranges, an M240 is accurate but does not have enough penetrating power against hard structures.
To achieve desired range capabilities to bridge this gap, the .338-caliber was chosen, specifically the .338 Norma Magnum over the .338 Lapua Magnum. This was due to several reasons, including greater barrel life and a less tapered case for better use in a belt link. At 1,000 yd (914 m), the 7.62 NATO's velocity drops to about 1,000 ft/s (300 m/s); at that range, the .338NM travels at 2,000 ft/s (610 m/s) and out to 1,100 yd (1,006 m), the round is capable of defeating Level III armour. The .338 Norma and Lapua rounds are both in service in New Hayesalia (along with the Stealth Recon Scout) and both weapons can be technically recalibred if necessary to fire each other's round.
A machine gun was designed around the concept with Short Recoil Impulse Averaging technology, uses available subsystem components to keep cost down, and has a broad view 6-power scope (unofficially titled the Spectre X) to enable point target engagement out to 1,000-1,200 meters.
Each 100 round box of .338 Norma Magnum ammunition weighs 4.1kg. A New Hayesalian soldier will generally carry 300 rounds on their person at any time.
To assist with the heavy weight load, the Reaper support system is fully certified for use with the Chief Wiggum.
