Objective Individual Combat Weapon
The Objective Individual Combat Weapon or OICW was the next-generation service rifle competition that was under development as part of the United States Army OICW program; the program was eventually discontinued without bringing the weapon out of the prototype phase. The acronym OICW is often used to refer to the entire weapons program.

A grenade launcher is a weapon that fires a specially designed, large-caliber projectile, often with an explosive, smoke, or gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary grenade cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organization by military forces.
