Abstract: With the deep development of the new round of scientific and technological revolution and military change, artificial intelligence and other cutting-edge technologies are reconfiguring the battlefield first-line treatment system. In the face of large-scale symmetric warfare, how to meet the demand for first-line treatment on the battlefield in future joint operations is a hot issue of concern for military powers in the world. We will systematically study the key role and implementation path of damage control theory in battlefield first-line treatment, analyze and summarize the practice status and problems of our army's damage control medical theory, innovate the concept and technology of damage control, promote the construction of our army's damage control medical system, and provide scientific support for the mission of "battlefield oriented, troop oriented, and future oriented".
