We should focus on basic training and specialized refinement of key and difficult courses, strengthen comprehensive, systematic, and case-based training based on complex and difficult conditions, enhance collaborative training with other branches of the military, promote deep coupling of combat training, and improve joint command, joint action, and joint support capabilities. Modern warfare is a confrontation between systems, a competition between systems. Each combat force can only fully demonstrate its power by coordinating with other combat units and elements to achieve overall linkage. The system combat capability of a military unit does not come out of thin air. It is necessary to actively create opportunities and conditions for "open door training", break free from the "service thinking" and "branch thinking", break down organizational barriers, connect the key points of the "alliance", generate the key ability of "unity", and truly forge the sword of victory in the system furnace. In the process of exploring the methods and paths of "open door military training", various units have shared and learned from each other in terms of combat chain, talent resources, combat training methods, innovative achievements, etc., forming a strong combat force through complementary strengths and weaknesses, and summarizing many useful experiences. Starting today, this newspaper is launching a series of reports titled "Deepening Practical Military Training and Focusing on Open Door Training". Please stay tuned. In autumn, in a certain sea area, waves roll and clouds fly, and the Changsha and Xianning ships of a naval detachment break through the waves and move forward. In the formation command post, the training staff and ship department head of the detachment are mixed with staff and battalion commanders from neighboring units such as the Navy Aviation and a certain unit of the Air Force to carry out collaborative command operations. The formation has arrived at the target sea area and will immediately launch a joint attack on the sea. The 'enemy' ship adopts electromagnetic silence to evade radar search. Inside the formation command post, Captain Li from a neighboring unit quickly mobilized reconnaissance forces for remote search. Although he successfully guided the warship to launch missiles, the destructive effect was not ideal. The training staff officer Wang of the detachment immediately analyzed the problem from their respective professional perspectives with Captain Li, unraveling the root cause: "There is a delay in the transmission of target information detected" and "there is a certain error in the calculated data"... Then, they combined the analysis results to carry out deduction, optimize the collaborative process, and explore and sort out a precise and efficient "collaborative action table". In the following training, each ship in the formation will use this "collaborative action table" to carry out collaborative training, effectively reducing attack response time and further improving strike accuracy. Only by embedding joint thinking at the end can we discover the weaknesses and deficiencies exposed in system training. At the same time, the formation and training of commanders from multiple branches of the military can help broaden the battlefield perspective. ”A formation commander said with deep understanding. It is reported that the detachment has established a training collaboration mechanism with multiple military units, not only jointly formulating joint training plans, but also coordinating and arranging training content, aiming to improve training quality and efficiency from the organizational planning level, and strive to achieve "one training, multiple benefits". This model has benefited the battalion commander of a friendly and adjacent unit. During a previous offshore training, as a member of the formation command post, he collaborated with the head of the naval intelligence department of the detachment to successfully seize the strike window, guide the battalion to launch missiles remotely, and accurately hit the target. Afterwards, Captain Yu further optimized the remote collaborative strike chain of the battalion based on this experience, improving the quality of command decision-making. The reporter saw on the training schedule of the detachment that not only did the mixed formation personnel cover multiple levels, but the scope of operations also expanded to various types of main warships. Nowadays, air force pilots enter the combat room of naval vessels, and naval unit staff and department heads enter the air force tower. These scenes have gradually become the norm for systematic military training. (New Society)
