The Army has selected three companies to develop prototype weapons it says will make ground pounders more lethal in future battles. The Army is tasking industry to come up with weapon and ammunition designs that will address some of the shortfalls it has seen with the current M4 and M249 Squad Automatic Weapon carried by most front-line units.
The key is the developing of the cartridge itself. The Army has asked industry to develop a round with a 6.8mm bullet. The bigger, heavier bullet will reach nearly double the distance with more lethal force than the smaller, 5.56 round.
