On a hot summer day, a ground guided brigade of the air force of the southern theater moved for thousands of miles and went to the Gobi in the northwest to carry out live troops and live ammunition training. (the chariot galloped toward the target position.) "Attacked and harassed by the 'enemy' unmanned reconnaissance plane!" During the maneuver, the echelon received a "enemy situation" notification, and the portable missile detachment quickly adjusted its position and launched a counterattack relying on favorable terrain. (the radar operator studies and judges the air situation and quickly captures the "enemy" target.) As soon as the "enemy situation" in the air was lifted, the special situation on the ground came one after another. "Unknown smoke was found in the front..." the officers and men of the anti chemical detachment immediately rushed to the "contaminated area" to quickly carry out screening, detection and decontamination. Subsequently, the echelon successively passed through the "poisoned area" and smoothly reached the launch site. (the sharp sword is drawn from its sheath to strike the attacking target in the air.) At this time, the wind was strong and the yellow sand was all over the sky. Officers and men did not fear difficulties and dangers, quickly seized positions, and successively completed pre war preparations such as communication construction, equipment erection, camouflage protection, etc. Soon, the radar detected the incoming target. In the command cabin, each combat unit responds quickly and stably tracks the "enemy" aircraft. According to the battlefield situation, the commander calmly responded to the command. "Launch!" At the command, several missiles took off one after another, roaring toward the target. (under the setting sun, officers and men quickly camouflage and protect themselves.) As night fell, the troops received a new combat mission. Under the dim light conditions, officers and men rushed to the battle position and started the night air defense battle... (Xinhua News Agency)
