Bushmaster fires in the desert.

The newest member of ATK's Bushmaster Chain Gun family, the Lightweight 25 mm (LW25), underwent successful test firings at the company's facility in Mesa, Arizona. The dual-feed LW25 was developed to provide multiple mission profiles and cover many of the operations currently served by .50-calibre machine guns and 40 mm grenade launchers. The LW25 is compatible with ATK's Programmable Air Bursting Munition (PABM), which is used to defeat targets in trenches, behind walls and around corners. The weapon features what the company terms as <<first round select>>, which allows the user to switch between two different types of ammunition.
