“We have the M855A1, essentially a brand new 5.56 ammunition that we currently use in the fight today in Afghanistan. It provides incredible increased lethality over the normal 855 round, and the amount of lethality that it provides gets it very close to a 7.62 in terms of capability. Since the early days of the Iraq war, when you used to hear [that U.S. troops would] pull the trigger and…they'd keep coming -- with this round that essentially stops that. When you hit someone with this round they essentially go down.”— Army Lieut. General William Phillips, military deputy to the Army’s top weapons-buyer, at a recent congressional hearing.
