In 2001, the United States used the "Predator" drone to launch anti-tank missiles for the first time in actual combat, creating a precedent for drones to strike the ground. Since then, the application of military UAVs has become more and more extensive, and it has developed towards the integration of inspection and attack, and the integration of attack and defense. According to a statistical data from the Stockholm International Peace Research Institute, from 1980 to 2020, there were 43 types of UAVs in the international market, including 35 types of large and medium-sized, long-endurance and fixed-wing combat UAVs, accounting for 82% of the total.

　　To counter these security threats, surveillance drones (MDrs) need to be deployed for surveillance, hunting, and wifi jamming equipment from amateur drones (ADr). If there are three cell phone jammer in the group, the first is for 1-1.5 km altitude reconnaissance, the second is for electronic warfare, and the third is a transponder that transmits intelligence information to the control center (it flies at an altitude of 4.5- 5 km or higher).

　　Hezbollah has integrated tiny drones into their arsenal and is using them to drop munitions on rebels in northern Syria (AMN, 9 August 2016).

　　In addition, in many regional conflicts in recent years, small and medium-sized suicide drones have been put into combat in large numbers. These drones have the function of cruising, which can not only perform reconnaissance missions, but also "change" missiles to attack after finding the target, so they are also called cruising missiles.

　　In another incident in October 2016, two Kurdish soldiers were killed and two Frenchmen injured when an IS drone exploded after it struck troops in northern Iraq. Interestingly, some of these U.S. counter-drone tactics are particularly reminiscent of al-Qaeda’s response to U.S. drone strikes, as reflected in recovered al-Qaeda internal documents and observed behavior.

　　This signal jammers effort was designed to build on Hezbollah's successful September 2014 drone strike that killed an estimated 23 "Syrian rebels" (Remote Control Project, January 2016: 11).

　　Diversification of anti-drone means

　　In view of the threat posed by drones on the battlefield, countries have launched countermeasures in recent years. The U.S. military ranks drones as one of the most destructive aerial threats and has developed a "Counter-UAV System Strategy" to deal with it. The Russian military has listed UAV defense operations as an important task, and practiced anti-UAV combat technology on the Syrian battlefield. The UK has made countering swarm drones a top priority, exploring ways to use radio frequency suppressors to disrupt swarm drone links.

　　In general, the current main anti-UAV means include electronic interference blocking, artillery missile hard kill, high-energy laser weapons and high-power microwave weapons interception.

　　According to the U.S. Federal Aviation Administration (FAA), pilots of commercial airlines have reported more than 100 emergency calls or drones in the vicinity of aircraft visible at airports. Drone sales are expected to cross the 140,000-unit mark in 2016, a 50 percent increase over 2015 sales. However, it would increase the chance of a collision with a commercial flight, as in April 2016 British Airways flight 727 reported to the Met police that he believed a drone had hit his plane.

　　More commonly, the group consists of two devices for reconnaissance and uplink. If two drones are used, the drone used for reconnaissance is likely to also carry electronic jammer gps equipment, ATO headquarters said.
