Wang Kai, Wen Xiaopeng, and Lv Xuezhi's Introduction: Lenin once said, "Without understanding the times, one cannot understand war. In recent years, with the widespread application of information intelligence technology in the military field, technology and tactics are being deeply integrated. Relying on advanced networked information systems, a "ubiquitous" combat system with highly dispersed forces, highly mobile organizations, and highly coordinated actions has emerged, as well as a "ubiquitous" combat mode that is always present, ubiquitous, and uncontrollable and autonomous, in order to achieve decentralized deployment of joint operations, wide area mobility, and dynamic coordination Concentrated energy release. The era of ubiquitous warfare is driven by technological progress and theoretical innovation, constantly pushing the issue of war to a new height. The profound changes in the world pattern and military form have also introduced combat operations into a new stage. The concept, system, and tactics of war are constantly developing and changing, and the limitations of traditional combat methods to respond to new threats, carry out new tasks, and confront new opponents are becoming increasingly severe, It is imperative to innovate combat methods that meet the requirements of modern warfare. Technological development drives the restructuring of combat systems. After the development of new technologies reaches a certain stage, they will not change operations based on people's will. The rapid development and deep application of artificial intelligence technology have made the composition of the combat system more diverse. In addition to traditional reconnaissance, strike, protection, support and other systems, new systems such as intelligence, unmanned, data, and cognition have played a prominent role. The composition of combat forces is more refined and complex, and the battlefield space is all-encompassing and ubiquitous. It has become the norm for combat confrontation to have oneself and oneself. The evolution of war has led to the reshaping of combat mechanisms. War has evolved into a completely new form, and its inherent combat mechanism will inevitably undergo a qualitative change. The intelligent characteristics of modern warfare are becoming increasingly evident. The combat system exhibits characteristics of external chaos, internal refinement, system ambiguity, precise nodes, unclear centers, and dynamic balance. The combat forces are diverse and multi domain, and the battlefield space is fully dimensional. The combat time and space gap is becoming smaller and smaller. According to the traditional combat mechanism of the breakthrough system, it is difficult to meet the needs of a new form of warfare. Threat escalation forces a revival of combat philosophy. The constantly changing security threats require different ways to respond and resolve them. In today's era, the comprehensive use of various means such as politics, military, and economy in hybrid warfare poses security threats in multiple ways and across a wide range of fields. Opponents adopting "decentralized" combat deployments and actions greatly increase the difficulty of prevention. If traditional methods are adopted to respond, the effectiveness will be greatly reduced. This requires decoupling the combat system, disaggregating combat capabilities, and engaging in combat in a more autonomous, resilient, flexible, and distributed manner. Theoretical innovation leads to the reconstruction of operational forms. Once a consensus is reached on the collective understanding of combat, it may trigger a profound change in the mode of combat. Currently, the powerful military is generally accelerating the innovation of combat theory and constantly proposing new ideas and concepts. For example, the US military's "joint global command and control", the British military's "distributed forces", and the Russian military's "deep and deep campaign theory" all emphasize the implementation of operations in larger areas, more fields, and more complex environments. This continuous convergence of understanding provides an essential "matrix" for the breeding of new combat forms. The connotation and essence of ubiquitous warfare
