As the threat posed by drones has gradually increased, the United States has issued guidelines and requirements to solve this problem. In 2016, the U.S. Army tested a series of anti-UAV (C-UAV) solutions in a test, and issued a request for information (RFI) to confirm that it can fight against small drones under 20 pounds (maximum take-off weight 9.07 kg). Potentially mature solutions for humans and machines. According to the request for information, these tests are carried out to realize the security risks that small drones pose to military personnel in combat and domestic environments. In August 2017, the U.S. Department of Defense issued a new secret guidance document for defense of military personnel and drones near military installations. This is a direct response to the concerns of U.S. military officials, who expressed concern about the following: small drones of civilian enthusiasts may threaten U.S. military flights or operations; in Iraq and Syria, drones are increasingly affected by the "Welcome by combatants; Russian-backed Eastern Ukrainian armed forces use drones to attack government artillery positions.
In December 2017, the U.S. Army began to search for temporary short-range air defense and anti-UAV systems to deploy to the Stryker wheeled armored vehicle, and issued a request for proposals on December 5, 2017 to purchase 72 sets "Temporary mobile short-range air defense" (IM-SHORAD) systems, these systems need to be able to counter drones through kinetic and non-kinetic energy. In February 2018, the U.S. Army disclosed that it hopes to deploy two new systems quickly to protect the troops from "low, slow and small" drones. At the same time, it issued two consultation papers, one for rapid development, deployment and support. The mobile "low, slow and small" UAV integrated defense system (M-LIDS) drone jammer, one is the expeditionary "low, slow and small" UAV integrated defense system (E-LIDS). In June 2018, Leonardo DRS announced that it won the bid and will provide its complete mission equipment (MEP) solution to help the US Army enhance its temporary mobile short-range air defense capabilities.
