Pictures surfaced on Jan. 16 of a purported police-operated anti-drone missile system in Standing Rock, North Dakota, site of the months-long Native American protest against the construction of the Dakota Access Pipeline.
Jon Ziegler posted pictures of the alleged missile system on Facebook with a caption:
TODAY: Anti-drone missile system confirmed on top of a hill guarding the DAPL drill pad. Many water protectors made it further around the bend to the east closer to the drill site and were met with police and reports of mace used. We climbed up the hill on the west side right up next to the launcher.
A Twitter user posted a similar picture of the system on Jan. 16 with this text: "WTH A AN/TWQ-1 Avenger located on the DAPL work site near the Missouri River #NoDAPL [POTUS] #INDIGENOUS #TAIRP."
ArmyRecognition.com describes the Avenger AN/TWQ-1 Air Defense System:
...[V]ehicle is a missile mounted system which provides mobile, short-range air defense protection for ground units against cruise missiles, unmanned aerial vehicles, low-flying fixed-wing aircraft, and helicopters. In the early 1980s, the then Defense Systems Division of the Boeing Aerospace Company (now The Boeing Company) developed the Avenger air defense system as a private venture.
The Avenger Air Defense System, built by Boeing, forms an important element in the U.S. Army's Forward Area Air Defense (FAAD) architecture, which includes C2I, radars, platforms and missiles. The first production contract for 325 units was awarded in 1987.
The gyro-stabilized Avenger turret with Stinger missiles is mounted on a 4x4 HMMWV (High Mobility Multipurpose Wheeled Vehicle), but can also operate in a standalone configuration or mounted on a variety of military vehicles.
More than 1,100 Avengers have been produced and delivered to U.S. Army, Army National Guard and foreign customers. The Avenger system can be installed on other types of chassis, tracked and wheeled, and is also fully air-transportable.
