WASHINGTON: The United States Air Force is creating a new military speciality dedicated to defending its air bases against missile and drone attacks, after recent conflicts exposed vulnerabilities at American military installations in the Middle East and elsewhere. The move follows an internal review of the Iran war by senior Air Force commanders, who concluded that the growing threat posed by inexpensive but highly effective drones and precision-guided missiles requires personnel specially trained to protect military bases. According to Air & Space Forces Magazine, the Air Force also plans to establish dedicated air base defence units at selected installations.
