Multi target network reconnaissance and multi firepower coordinated resistance. In mid June, the air defense unit of a brigade of the 72nd group army moved thousands of miles to a strange area in the northwest to carry out live fire drills. After railway transportation, the troops arrived at the scheduled area. After unloading the equipment, the officers and soldiers quickly moved to the operational area as required, and the drill began immediately. Quickly hoist missiles and prepare for night combat. Launch portable missiles at the target. "Many 'enemy planes' were found in the southeast and southwest, making covert raids on our defense areas..." after receiving the air information notification, the commander relied on the early warning network composed of multi-type radars to identify and track targets and quickly study and judge the battlefield situation. "Launch!" At the command, missiles roared towards the incoming "enemy aircraft", marking a spectacular arc in the air. Just after the first round of fire attack, the air defense radar caught the low altitude attacking target. The commander immediately sent battle instructions to the anti-aircraft artillery unit through the integrated command platform, and the anti-aircraft artillery unit deployed hundreds of meters away immediately went into battle. In an instant, a shell pierced the sky, weaving an air defense fire network Missiles attack to intercept the incoming "enemy". In the desert, chariots gallop. The smoke of battle had not yet cleared, and the troops received the order to shift their positions. Hearing the order, the officers and soldiers moved quickly to the reserve position. Next, they will also be tested by many practical subjects such as night mobile warfare and air to ground confrontation. (outlook new era)
