Short range air defense
Short-range air defense (SHORAD) is a group of anti-aircraft weapons and tactics that have to do with defense against low-altitude air threats, primarily helicopters, low-flying aircraft such as the A-10 or Sukhoi Su-25, and low-flying UCAV and loitering munitions. SHORAD and its complements, HIMAD (High to Medium Air Defense) and THAAD (Terminal High Altitude Area Defense), divide air defense of the battlespace into domes of responsibility based on altitude and defensive weapon ranges.
