From pistol rounds to artillery shells, the Army is developing a host of new ways to destroy targets large and small. The service is working on one-way tracer rounds for current standard rifle ammunition and reduced-range training rounds for some of the same cartridges. Army scientists are building new rounds for the 120mm tank rounds. Col. Steven Power, project manager of maneuver ammunition systems, is developing airburst options and proximity sensing in a selection of rounds. The Army is finding ways to jam and disrupt signals and is also working on improved airburst rounds for the Apache attack helicopter. Developers are also working on the one-way luminescent tracer, or OWL, round for 5.56mm, 7.62mm, and the Next Generation Squad Weapon’s 6.8mm round. The Army is pushing for more at-home station training to accommodate different round calibers, including 7.62mm, .50 caliber, and 6.8mm.
