A medium-range air-defense missile system attached to an air-defense brigade under the PLA Xizang Military Command fires a surface-to-air missile during a recent live-fire training operation at the altitude of 4,500 meters in southwestern China's Xizang Autonomous Region. The brigade conducts such training subjects as long-distance and round-the-clock real combat live-fire training operation, reconnaissance, electronic interference operation, and so on, in order to test troops’ air-defense capabilities.
