Army Testing 'Iron Man' Suit Component for Next-Gen Squad Weapon The aim control enhancer, or ACE, weapon stabilizer device being evaluated for the Army’s next Generation Squad Weapon effort. (Matthew Angle, ACE designer) 27 Jan 2021 One day soon, U.S. infantrymen could go into battle with Next Generation Squad Weapons equipped with a compact, mechanical stabilizer designed to drastically improve accuracy, especially when shooting from a standing, unsupported position. The aim control enhancer, or ACE, was once under consideration to be part of U.S. Special Operations Command's now-defunct "Iron Man" suit program. Now, the device is being evaluated as part of the NGSW effort.
