The organization is modeled after an agency the Pentagon formed two decades ago to counter improvised explosive devices that insurgents used against U.S. troops in Iraq and Afghanistan. The Army oversees drone defense for the military. But critics of the Army's past approaches have said its counter-drone defenses are built on older technology and are not adaptable enough, given how quickly the drone threat has evolved on the battlefield in Ukraine. New technologies can detect and identify incoming drones, then take them out more efficiently. Older technology, critics say, is poor at identifying drones, including which ones pose the most acute and immediate threat.
