A brigade of the 72nd Group Army and the Air Force jointly innovated the confrontation training mode - the Army Training Ground ushered in the air "joint blue army". President Xi stressed in the report of the 20th CPC National Congress that "deepen joint training, confrontation training, and scientific and technological training". Confrontation training has become the main training means and means to improve the combat effectiveness of the army with the characteristics of realistic situation, fierce resistance and close to actual combat. To deepen confrontation training in the new era, it is necessary to jump out of the familiar environment and known topics, break the concept of "acting like" and "guiding and performing oneself", integrate into joint operations, and upgrade the confrontation system. A brigade of the 72nd Group Army and the Air Force worked together to innovate, walk away from the new way of confrontation training, and enhance the joint forces of training and preparation under the new system. The wind and cloud change, and the eagle rises and falls. In the early spring, a brigade of the 72nd Group Army launched an air defense drill. "The 01 groups of targets rely on the southwest mountain cover, and the 02 groups of targets penetrate at ultra-low altitude..." We can see that the blue target formation is attacking separately, sometimes at low altitude circuitous, sometimes at serpentine maneuver, skillfully using the red radar blind area to carry out covert raids. In the Blue Command Post, the reporter saw that not only the brigade's target support professional officers and soldiers, but also the pilots and electronic countermeasures unit personnel from a certain part of the Air Force were commanding and operating the target aircraft. The blue side has a strong lineup, and the red side is not mediocre. In the face of the lure of the blue target, the red side stood still, the radar remained silent, and only when the target was close to the critical point could it be turned on immediately, and multiple targets were accurately locked. At the critical moment, the blue side personnel from a certain department of the Air Force decisively used the electronic countermeasures force accompanying the support to interfere with the "enemy" and release multiple false targets. Suddenly, the Red Party fell into a passive position. The blue side took this opportunity to turn the situation around, and finally succeeded in breaking through and winning the confrontation. Although he stumbled, Zhou Xuhui, the commander of the Red Army, looked excited. He told the reporter: "In the face of the 'united blue army' formed by the army and the air force, it is not easy to fight this battle. But it is difficult to fight against the experts. It is very enjoyable to fight against the experts, and it has learned lessons, and it has also learned experience and thinking." In the past, due to the single flight action of the target aircraft and the same tactical tactics, it is difficult for the air defense unit to capture and attack the target, often because the missile is out of the sheath. Zhou Xuhui said frankly that the blue "grindstone" is not hard, and the "gold content" of the confrontation is not high. "The report of the Twentieth National Congress of the Communist Party of China emphasized 'deepening joint training, confrontation training, and technology training'. During the study and exchange, everyone was inspired and strengthened their confidence in training innovation and war method innovation." The leader of the brigade said that since the end of last year, they have selected target aircraft operators to air force colleges and training institutions for study and exchange, and invited air force pilots to introduce the flight modes and attack modes of various aircraft types to the officers and soldiers of the air defense unit, Help officers and soldiers improve their actual combat skills. "It is necessary not only to form a 'mixed formation', but also to form a 'collusive war'." With the "United Blue Army" appearing in the training ground, the brigade introduced the key points of air force penetration and assault into the flight training of the Army's target aircraft, optimized the flight route and attitude for different regions, different tasks and different adversaries, and coordinated with the new field and new quality combat forces such as electronic jamming, to continuously improve the penetration success rate, and forced the air defense unit to upgrade and improve the combat method.
