During the War of Resistance, Gong Xueli often fought tough battles with his sharp blade, which was sharpened by hard stones; Excellent quality, forged by strong opponents. During his inspection of the Air Force in the Western Theater Command, President Xi Jinping emphasized the need to strengthen practical adversarial training. Adversarial training is one of the most effective ways to strengthen practical combat training, which plays an important role in understanding the bottom line of abilities and improving practical combat skills. War is a confrontational activity between the enemy and ourselves, and the essence of practical training is confrontational training. The report of the 20th National Congress of the Communist Party of China pointed out that we should deepen practical military training, deepen joint training, adversarial training, and technological training. Conducting solid adversarial training is beneficial for better studying opponents, deepening the application of tactics and training methods, and testing the quality of military training. Practice has proven that the more "like" the enemy situation is set, the more "true" the environment is set, and the more "lively" the situation is set, the more one can discover their own problems. As Marshal Liu Bocheng said during an exercise, "In confrontation, we must be enemies of each other. Will the enemy be kind to you? Will you be soft on the enemy? We usually engage in stronger confrontations and only fight hard battles on the battlefield." Modern warfare is a confrontation between systems, a competition between systems, with more comprehensive elements, greater intensity, and higher cruelty, involving information networks, reconnaissance intelligence, command and control Comprehensive security and other fields. This puts forward new and higher requirements for adversarial training. We must not only organize adversarial training between individual soldiers, single equipment, units, and units, but also continuously deepen platform, system, and system adversaries; We should not only establish more dangerous situations, crises, changes, and difficulties, but also integrate adversarial training into every process of generating the combat capability of the system. Clausewitz once said, "War is not a pastime, it is not a pure entertainment that pursues adventure and gambling, nor is it a product of inspiration, but a serious means taken to achieve serious goals." Since ancient times, there has been no runner up on the battlefield. The battlefield is a life and death battle between the enemy and ourselves, and strengthening adversarial training is the first test of future warfare. Fight more in peacetime and fight tough battles in wartime. Each unit should innovate training models, deepen adversarial training, target strong opponents, focus on key tasks, focus on ability testing, and innovate and apply practical tactics and training methods; Promote the construction of a practical training environment and adversarial conditions for the system, and build a blue army force system with moderate scale, complete elements, and efficient synthesis according to the standards of "knowing the enemy, resembling the enemy, surpassing the enemy, and winning the enemy"; Strengthen and improve the construction of adversarial training conditions such as military chess systems, network platforms, and live combat systems, improve adversarial training mechanisms, establish and improve institutional norms such as organizational implementation, process supervision, adjudication and evaluation, and operational support, promote the transformation of military training from intangible "training with enemy information" to tangible "fighting against powerful opponents", and ensure that adversarial training truly resists and becomes strict in an environment similar to real combat.
