Not long ago, a certain unit joined hands with neighboring units to conduct joint training, comprehensively testing the joint combat capability of the troops and achieving significant results. This enlightens us that in order to deepen practical military training and strengthen military preparedness, we must adhere to systematic training and deepen joint combat training. In modern warfare, there is no war, no alliance, and no alliance is invincible. With the acceleration of the evolution of warfare towards information-based and intelligent warfare, integrated joint operations have become the basic form of combat, and platform operations, system support, tactical actions, and strategic support have become prominent features of modern warfare. To enhance joint combat capabilities and win future wars, it is necessary to solidly conduct joint training, so that the troops can move from "building blocks" to "blood ties", and turn "hard fingers" into "iron fists". We need to fight together and train our troops systematically. To carry out joint training, we need both "core connection" and "heart connection", both "form connection" and "spirit connection", truly enabling all combat forces, elements, and units to achieve unified intentions, share information, and coordinate actions. It has been proven that only by actively integrating into the joint operation system and relying on system aggregation can the joint benefits of "1+1>2" be achieved. Currently, faced with the heavy task of preparing for military struggle, we must firmly establish the concept of joint victory, solidly carry out joint training, extensively carry out realistic joint exercises, accelerate the improvement of integrated joint combat capabilities, and promote the development of joint warfare and training in depth.
