PICATINNY ARSENAL, N.J. (June 23, 2010) -- The Army announced today it has begun shipping its new 5.56mm cartridge, the M855A1 Enhanced Performance Round, to support warfighters in Afghanistan.
The new M855A1 round is sometimes referred to as "green ammo."
The new round replaces the current M855 5.56mm cartridge that has been used by U.S. troops since the early 1980s.
The M855A1 resulted in a number of significant enhancements not found in the current round, officials said. They explained these include improved hard-target capability, more dependable, consistent performance at all distances, improved accuracy, reduced muzzle flash and a higher velocity.
