In the golden autumn, a live combat drill was held in a brigade of the 74th Army Group. The multi-disciplinary attack and defense of multiple arms, the combination of precision damage with shells and guns, and the combination of information and fire to win... The close cooperation of different arms and specialties has become the highlight of this drill. "The 'enemy' interpenetrating units are advancing towards your department in depth!" After receiving the notification, Wu Taibai, the Red Commander and a battalion commander, ordered the reconnaissance platoon to conduct reconnaissance. In a moment, several UAVs were launched and sent back the situation ahead in real time. After analyzing, studying and judging, Wu Taibai sent the information to the fire unit. The fire unit sets the firing data accordingly to strike the "enemy". "The effect of '1+1>2' can only be achieved by making overall use of all operational elements and forces of different arms within the organizational system." Wu Taibai said with emotion that this is not only a summary of the experience of this drill, but also a gain after deep reflection on the lessons learned in the past. In a previous drill of the battalion, the armor unit that was the main attacking task charged ahead, but it fell into the blue "trap" because it ignored the cooperation with reconnaissance, communication, artillery and other forces, causing heavy losses. When reviewing and summarizing, they realized that after the adjustment and reform of the army, the professional strength of the formed battalion increased, and the operational style and concept must be changed accordingly. In particular, they should pay attention to the coordination of various professional forces to improve the operational capability of the system. Only when the fingers are clenched into fists can the resultant force be formed. The brigade drew inferences from one instance and set off "brainstorming" among officers and soldiers. It regularly organized commanders to carry out problem discussion in combination with theoretical learning, and constantly strengthened the sense of coordination in ideology; Adjust the training method according to the idea of detailed training and module grouping strengthening, and embed professional training and assessment into the grouping operation; Combine the elements of the combat process to organize joint training, "combine" various courses such as attack and defense, mobility, and support, and exercise the overall combat capability. In addition, they have also changed the practice of training talents solely by specialty, boldly explored the talent training mode of "one professional and versatile, one post and multiple standby, one soldier and multiple use", improved the comprehensive quality of officers and soldiers through cross training, cross specialty training, etc., and cultivated a group of "versatile players" who can change posts at any time. Reviewing, efficiency evaluation, experience exchange... It was getting dark. After the drill, officers and soldiers had no time to rest, so they carried out in-depth discussion in combination with the use of tactics to improve their combat capability in summary. (Liu Xinshe)
