At sea, warships dance through the sea and waves, their swords pointing towards deep blue; In the air, fighter squadrons roared into the sky and launched fierce attacks... In the middle of winter, a sea air joint training suddenly began against the backdrop of a real battle in the Southern Theater Command. The Joint Operations Command Information System operates efficiently, with operational instructions directly from the joint command center of the theater to the front line, commanding various combat forces, units, and elements of multiple branches of the military to organically integrate into the "big chessboard" of joint training. A number of new combat methods have been validated on the joint battlefield. The system "hardens" and accumulates the "confidence" of joint warfare. The theater of operations, with a sense of urgency and a sense of crisis, insists on leading training through combat, deepening the coupling of combat and training, highlighting case based training and system based joint training, and steadily advancing the specialized research and training of typical joint action combat formations, comprehensively enhancing the theater of operations' joint command capabilities and the level of practical training for troops. At dawn, in the direction of the South China Sea, war eagles howled, "dragons" were mobilized, and radar flew around... Under the unified command of the Joint Command Center of the theater, various task forces worked together closely, quickly building a multi domain joint, hierarchical deployment, and both offensive and defensive battlefield layout, flexibly conducting sea and air escort and deterrence evacuation exercises. The solo performances of each branch of the military in the past have now converged into a magnificent symphony of military training. Under the overall command of the theater of operations, all branches of the military implement the principle of "joint combat and systematic training of troops". The research on combat training needs, planning of training content, measurement of evaluation standards, and implementation of training tasks are integrated. In addition, the theater focuses on the shortcomings and weaknesses of the combat capabilities of the system, establishes a list of training problems, rectification lists, and responsibility lists, and solidly promotes the continuous improvement of the quality and efficiency of military training. Enhance the effectiveness of joint operations and training in difficult, risky, and perilous situations. The theater regards understanding opponents and understanding the battlefield as the first checkpoint for military training and preparation. The theater's joint command center regularly organizes enemy situation analysis, situation deduction, etc., updates the combat database in real time, accurately transforms battlefield requirements into training topics, and achieves mutual promotion and progress in combat and training, and results sharing and utilization. The training plans of each unit are dynamically adjusted around the needs of actual combat, with courses targeted at the real battlefield and accurately set, making every joint training a "rehearsal" of actual combat. In the open sea and ocean, a new type of destroyer is sailing at high speed, cutting through waves and waves, trying to break through the "invisible" electromagnetic interference. At the same time, a drone formation of a certain brigade of the air force in the theater conducted reconnaissance, and battlefield information continuously flowed to the theater's joint command center. A fierce "breakthrough" and "strangulation" battle broke out... Thousands of miles away, a battle alarm suddenly sounded on the air defense position of a certain brigade of the army in the theater. Faced with the airborne incoming target signals flashing on the radar screen, the commander calmly responded and organized officers and soldiers to quickly identify, track, and lock onto the "enemy". Each firepower unit launched a counterattack based on the automatic allocation of targets. Union is not simply a physical superposition, but rather the formation of a "chemical reaction" that is tested in the real struggle. The theater fully leverages its role as a hub for joint operations and training, combining the complex situation and mission tasks faced by the theater, regularly organizing joint exercises and training, strengthening innovative command and operation practices, streamlining the upper, lower, left, and right command interfaces, and ensuring the stable operation of the joint based training mechanism. The practical response to military struggle is like a sharpening stone, sharpening the sharpness of the system's strength. The wind and thunder are raging, and the war drums are urging the expedition. The Southern Theater Command and various branches of the military are taking on the responsibility of "going to the battlefield at any time", waiting eagerly and fighting hard to defend the "southern gate" of the motherland, honing their courage to fight and win, and forging an iron fist for joint victory.
