Soldiers are the defenders of the country, and those who are not strong and powerful are beyond their control. Physical fitness is the foundation of combat effectiveness construction. In times of war, revolutionary predecessors repeatedly used their "iron feet" to beat the enemy's "car wheels", demonstrating that strong physical fitness is a strong guarantee for winning battles. During the Red Army period, no matter how intense the battles were, each unit still carried out military sports training such as mountain climbing according to local conditions, ensuring that officers and soldiers always maintained sufficient physical fitness to adapt to the difficult and cruel battlefield environment. In the new era, with the accelerated evolution of informatization and intelligence, combat tasks have become more diverse, weapons and equipment have become more diverse, and combat environments have become more varied. The requirements for physical fitness to win battles have not decreased, but have become more detailed and accurate in terms of scientific, refined, and practical standards. This reminds us that in order to win future wars, we must focus on the needs of combat and broaden the concept of physical fitness, and strengthen the "comprehensive physical fitness" required on the battlefield. How to fight, how to train soldiers; Whatever is needed on the battlefield, officers and soldiers will practice. Modern warfare has put forward new and higher requirements for the physical fitness of officers and soldiers. Different positions and battlefield environments require different emphasis on physical fitness indicators such as strength, speed, endurance, flexibility, agility, and coordination. Practical training can only target specific combat needs, promote training transformation based on the outline, and use practical training to enhance capabilities, in order to truly improve the "supply side" quality of military physical training and provide strong support for combat operations. The new version of the "Military Sports Training Outline" closely follows the actual situation of military branches, closely connects with specialized physical fitness needs, scientifically sets typical training scenarios, and accurately customizes training courses. At the same time, in accordance with the principles of "focusing on special needs, simplicity and feasibility, modular training, and intensive examination", a content system of "stage training+practical examination" is created to couple the training content with the physical needs of officers and soldiers, match the movement mode with the characteristics of job operations, and align the training methods with physical fitness requirements, ensuring that officers and soldiers always maintain a good combat state.
