@militarymechanicsie: The U.S. Army has begun fielding Sentinel A4, its next-generation 360-degree air defense radar, marking a major leap in how ground forces detect and track aerial threats. Built around an active electronically scanned array, Sentinel A4 is designed to spot cruise missiles, drones, aircraft, helicopters, and rockets in a single, continuous battlespace picture. This isn’t just a new radar, it’s a new set of eyes for the Army’s air defense network.
