 The gun, officially designated as the medium caliber anti-armor automatic cannon (MCAAAC), has been already developed by Ares Inc. During development the original Ares Inc. made replenisher proved to be problematic and was replaced with one made by Meggitt Defense.Following the end of the Cold War some theorists believed that the existing suite of U.S. armored vehicles, designed largely to fight Soviet mechanized forces in Europe, were not well suited to the lower-intensity missions U.S. armed forces would be tasked with.This led to the development of a new armored fighting vehicle designed for lower-intensity combat, rather than large-scale battle.
