Military training is an "incubator" for the generation of combat effectiveness in the army and a "rehearsal ground" for future wars. In today's rapidly evolving form of warfare towards intelligence, the combination of virtual and real as a "bridge" connecting training and actual combat not only carries the fundamental principle of "training for war", but also reflects the requirements of the era of "war promotes training". The key to accurately grasping the combination of virtual and real in military training is to use combat effectiveness as a benchmark, calibrate the balance point between "virtual" and "real" in training practice, and transform the quality and effectiveness of training into the ability to win battles. In military training, "real" refers to actual equipment, real-life situations, practical training, etc., relying on real weapons and equipment, battlefield environment, providing trainees with the most direct and authentic combat experience; Virtual "refers to training conducted using simulated weapon systems, simulated combat environments, fictional battlefield situations, and artificial intelligence based virtual enemy forces. Reality is the foundation of combat effectiveness, and practical operations hone the accuracy of the use of weapons and equipment by officers and soldiers. Real combat tests the tacit understanding of collaborative cooperation, and live ammunition shooting verifies the effectiveness of firepower strikes. Virtual "is the" catalyst "for generating combat effectiveness. Virtual operations enhance the proficiency of officers and soldiers in using weapons and equipment, virtual simulations simulate complex enemy situations, and military chess simulations hone command and decision-making abilities. The essence of the combination of reality and virtuality in military training is the dialectical unity of practice and theory, reality and virtuality. The effective combination of the two can stimulate the doubling of combat effectiveness. The combination of virtual and real training is not a simple technical overlay, but a systematic engineering involving training concepts, content, methods, and guarantees. In modern warfare, the battlefield situation is constantly changing, and the advantage of single equipment performance is no longer able to determine the outcome of the battlefield. Only through effective training that combines virtual and real elements can officers and soldiers feel pressure in the "real" environment and deduce strategies in the "virtual" space, in order to achieve a step-by-step leap in "individual skills collaborative ability system effectiveness". To this end, we should establish the training concept of "leading training with war and promoting war with training", scientifically construct a training system that combines reality and virtuality, and achieve mutual promotion and collaborative efforts. One is to take demand as the driving force and design a top-level architecture that combines virtual and real elements. Establish a closed-loop mechanism of "requirements design verification feedback", distinguish strategic, campaign, and tactical levels, and allocate the content and time ratio of "virtual" and "real" reasonably according to the characteristics of different military branches, training stages, and combat tasks. The second is to use technology to empower and expand the space for combining reality and virtuality. Establish a virtual real training big data center, improve the "data closed-loop" mechanism, collect data on action trajectories, decision times, equipment parameters, and other aspects of virtual real training, utilize machine analysis capabilities to identify weaknesses, generate personalized training plans, and enhance the ability to handle situations in multi-dimensional combat scenarios. Thirdly, guided by practical experience, we will strengthen the quality and effectiveness of the combination of reality and virtuality. Centered around the concept of "strengthening reality with virtuality and promoting virtuality with reality", we drive scene innovation through practical needs, quantify training effectiveness through technological means, and promote the transformation of training quality and effectiveness from quantity accumulation to quality. The fourth is to use talent as the support and activate the combination of virtual and real entities. On the one hand, strengthening the learning and discussion of virtual simulation, data processing and other technologies, cultivating the ability of officers and soldiers to use virtual systems, analyze training data well, and innovate training methods; On the other hand, establish a talent exchange mechanism of "cross rotation", promote "those who understand combat and technology, and those who understand technology and training", and cultivate a team of versatile talents.
