From the Document: "The Department of Defense (DOD) defines a precision-guided munition (PGM) as a 'guided weapon intended to destroy a point target and minimize collateral damage.' This includes air- and ship-launched missiles, multiple launched rockets, and guided bombs. PGMs typically use the global positioning system (GPS), laser guidance, or inertial navigation systems to improve a weapon's accuracy to reportedly less than 3 meters (approximately 10 feet). Recent operations have heavily relied on PGMs for counterinsurgency operations. The recent National Defense Strategy articulates a renewed focus on great power competition to combat anti-access/area denial (A2/AD) systems. The wide proliferation of A2/AD is likely to increase the operational utility of PGMs. In particular, peer competitors like China and Russia have developed sophisticated air defenses and anti-ship missiles that increase the risk to U.S. forces entering and operating in these regions. As a result, DOD has argued it requires longer-range precision munitions to meet these new threats."
