"Many countries view ballistic and cruise missile systems as cost-effective weapons and symbols of national power. These weapons present an asymmetric threat to US forces. Many ballistic and cruise missiles are armed with weapons of mass destruction. However, numerous types of ballistic and cruise missiles have achieved dramatic improvements in accuracy that allow them to be used effectively with conventional warheads. These highly accurate weapons can be used in anti-access/area denial (A2/AD) missions. The term A2/AD refers to capabilities designed to deter or counter adversary forces from deploying to or operating within a defined space."
