  engagement or opt to seek cover after launch. The grip stock is reused continually until failure. After firing,
  the gunner has no control over the missile and is required only to observe the missile's flight trajectory to the
  target.

  SENTINEL
  A-9. The Sentinel radar (figure A-4 on page A-5) is an X-Band, pulse-Doppler phased array radar that
  provides 360-degree curing and target identification. It’s extremely low noise design and Doppler signal
  processing result in exceptional ability to detect small, low-flying targets in clutter. It can acquire, track, and
  classify cruise missiles, UASs, and fixed- and rotary-wing aircraft. The Sentinel can detect and classify
  rotary-wing aircraft, including hovering rotary-wings, at ranges beyond firing unit's maximum weapon
  detection and engagement range in a severe electronic countermeasures environment. Targets can be detected
  and tracked in all weather, day or night, under the most extreme battlefield conditions. Sentinel's air defense
  interrogator provides improved identification friend or foe to aid in positive identification and preventing
  fratricide. Due to its three-dimensional pencil beam and frequency-agile mode of operation, the Sentinel is
  difficult to detect and locate accurately, improving its survivability.
  A-10. The Sentinel radar is towed by a heavy high mobility multipurpose wheeled vehicle with a mounted
  10-kilowatt generator in the rear of the vehicle. Sentinel is capable of 24-hour operations and can be located
  within 10 kilometers of the forward line of own troops if the mission and situation so dictate. It should have
  a clear field of view (360 degrees), be positioned to ensure overlapping coverage with adjacent radars such
  that their search areas do not leave any seam in the defense that might be used by incoming threats, and
  should be placed away from power sources of similar radiating frequency bands to avoid interference.
  A-11. Sentinel is air transportable by medium-lift rotary-wing aircraft for the high mobility multipurpose
  wheeled vehicle variant, and by transport fixed-wing aircraft for the medium tactical vehicle variant. For
  more information on the Sentinel system, see ATP 3-01.48.
