  Figure A-5. Land-based Phalanx Weapon System
  A-14. The Land-based Phalanx Weapon System leverages ADA and field artillery sensors to provide alerting
  and cueing of incoming threats. The Sentinel radar and AN/TSQ-50 Lightweight Counter Mortar Radars are
  organic to the Land-based Phalanx Weapon System formation. The Lightweight Counter Mortar Radar is
  operated as either a counterfire sensor (Special Operations Command mode) or in the counter-RAM mode.
  It provides 360-degree surveillance and about 7.5-kilometer range. In either mode, the Lightweight Counter
  Mortar Radar detects RAM fire, and predicts the suspected points of origin and impact. In the counter-RAM
  mode, the Lightweight Counter Mortar Radar utilizes either the local area network or high-speed radios to
  send this data to the Forward Area Air Defense C2 to be used for track confirmation/correlation, cueing of
  other sensors, and countermeasures (by relaying data to friendly artillery and air assets). The Land-based
  Phalanx Weapon System also pulls data from the AN/TSQ-53 Firefinder radar while Firefinder is executing
  is primary counterfire mission. In addition, the AN/TPQ-36/37/46 counterbattery radar found in forward
  operating bases with field artillery units may be tied into the sensor network.
  A-15. The RAM Warn system (figure A-6 on page A-7) capability provides localized RAM early warning
  and impact point prediction and can be used within Land-based Phalanx Weapon System units or as an
  independent warning capability. RAM Warn system uses local sensors and a network of broad area sensors,
  as available, to sense attacks and disseminates warnings using audio and visual methods, both outdoors and
  indoors. Warnings are limited to the zone of danger, not to an entire base or AO unless directed by the
  supported asset commander. Emplacement considerations in positioning RAM Warn system components
  include the size of the defended area, heavy traffic areas, designated logistical arrival and departure points,
  and dead space areas.
