The Northern Desert is filled with warm winds. Recently, a multi-platform comprehensive exercise under the background of a practical battle in a certain brigade of the 81st Group Army is currently underway. During the drill, the brigade changed its previous professional training mode of "separate training+continuous assessment" and explored a set of "integrated" training and assessment methods for composite units, allowing multiple arms to participate and multiple weapon platforms to "package" and engage in confrontation, forcing officers and soldiers to use tactical tactics according to the battlefield situation. During the implementation phase of the battle, if the artillery reaction time is reduced by 20%, the survival rate of the fleet on the battlefield can be improved by nearly 10%... "Walking off the training ground, Xu Wutao, the director of the Blue Army Research and Training Center of the brigade, led the officers and soldiers to summarize and analyze the training data as soon as possible, verifying the" actual combat contribution rate "of this new training mode, and providing data support for the improvement and promotion of subsequent combat methods. Xu Wutao is often affectionately referred to as "Dr. Xu" by the officers and soldiers of the brigade. It is not that he has a doctoral degree, but because he has been studying the Blue Army for more than ten years, his enthusiasm for thinking and researching warfare, and his rich knowledge of tactical warfare, that his comrades admire him very much. That year, the army formed the first specialized blue army and established a blue army research and training center. As a highly qualified training staff officer, Xu Wutao became a suitable candidate in the eyes of the brigade leaders and began to take on the responsibility of exploring and tackling key problems. The difficulty of the beginning can be imagined. Without a model to learn from, and without textbooks and materials, each step requires arduous exploration. "Our 'sharpening stone' is charged with the glorious mission of testing the combat effectiveness of all forces, and only success is allowed, no failure is allowed." When the center was inaugurated and operated, Xu Wutao set a high standard for himself and the officers and soldiers - to simulate the most real and vicious opponents. Over the years, Xu Wutao led the research team to translate millions of words of foreign language materials, compile them into three volumes of the "Blue Army Construction Guide", collect and organize multiple sets of books, magazines, and video materials, and compile materials such as the "Outline of Training and Assessment for Simulated Blue Army Units", setting a benchmark for the professional construction of the entire army's simulated blue army. "The mission of the 'sharpening stone' is not to win or lose, but to help the opponent to improve his fighting skills. We should not only be a strong opponent, but also be a good teacher." With the gradual deepening of research, Xu Wutao has a more in-depth thinking on "how to be a good sharpening stone". ——Thinking about plane and three-dimensional. During a confrontation exercise, a newly built composite brigade serving as the Red Army had advantages in multiple professional branches such as engineering and chemical defense, but the commander's military thinking remained focused on plane confrontation, resulting in loopholes in the allocation of troops. At this point, the Blue Army, who was already familiar with the "way of synthesis," could have won quickly. However, Xu Wutao and his comrades ultimately chose to pause their frontal attacks and implement multiple actions such as electromagnetic suppression and special forces attacks, gradually forcing the Red Army officers and soldiers to strengthen their synthesis thinking. When the drill was resumed, a Red Army commander said with emotion: "Thank your opponent, this battle is a vivid transformation practice lesson." - Thinking about the main character and supporting role. In recent years, joint exercises and training have gradually deepened, and it is urgent to improve the joint and systematic combat capabilities of the troops. Xu Wutao led his team to visit more than 10 military colleges and universities, consulted military experts on joint operations knowledge, and entered the electronic warfare force to study electronic warfare. Taking advantage of the training and practice, he invited land and aviation combat personnel to give on-site lectures... "Adapting to the requirements of system warfare,
