Background
A sentry gun is a weapon that is automatically aimed and fired at targets that are detected by sensors. The earliest functioning military sentry guns were the close-in weapon systems point-defense weapons, such as the Phalanx CIWS, used for detecting and destroying short range incoming missiles and enemy aircraft, first used exclusively on naval assets, and now also as land-based defenses.

The weapon system mounts a .50BMG automated M2 Browning machine gun and a SPIKE guided missile in each pillbox covered by an opaque protective shield. The weapon is operated by one soldier and fed information from cameras, long range electro-optical sensors, ground sensors, manned aircraft, and overhead drones, as well as radar.
