NIOA will be displaying the General Dynamics Ordnance and Tactical Systems (GD-OTS) LWMMG (Lightweight Medium Machine Gun) at the Land Forces Expo with representatives from GD-OTS in attendance.

NIOA first demonstrated the GD-OTS LWMMG at their Land Forces Conference Live Fire event in 2012, validating the superior ballistics of the .338 Norma Magnum round and it’s potential to provide an enhanced direct fire support capability


Improvement in optics has extended the range of the modern battlespace, creating a new requirement for a round such as the .338NM that can deliver increased accuracy and lethality at those extended ranges. Additionally, the proliferation of Level III body armour, which cannot be defeated by 7.62mm NATO rounds at extended range, further strengthens the necessity for an extended range direct fire support solution.

The LWMMG offers a distinct advantage in both extended and close-in fighting, eliminating the gap between 7.62mm and .50 calibre weapons. It utilises the highly efficient .338 Norma Magnum cartridge to offer accuracy and lethality while extending the battlespace out to 1,700 metres. Capable of defeating Level III body armour and incapacitating soft-skinned vehicles at 1,000 metres, the LWMMG’s .338NM round delivers in excess of 1,900ft/lb of energy to the target, more than four times that of the 7.62mm NATO round.

The patented technology of the Short Recoil Impulse Averaging mechanism substantially reduces recoil and improves target retention during automatic fire. With an operational weight of 10 kilograms and featuring a fully collapsible stock, the LWMMG offers superior mobility and portability in both mounted and dismounted operations
