In spring, the snow covered plateau is still cold with gusts of wind. As soon as the officers and soldiers of a certain unit of the Air Force of the Western Theater Command arrived at the training ground at an altitude of 4800 meters, they encountered a series of special situations. The maintenance technician led the repair team to accurately eliminate the faults and the training proceeded smoothly. From snowy plateaus to dense forests in the southern regions, from deep seas and oceans to virtual spaces, all units of the military actively strive to create hazardous environments, difficult conditions, and strong opponents, effectively promoting the improvement of practical training levels. In a full-scale combat launch training of a certain Rocket Force unit, a "special intelligence database" consisting of multiple typical scenarios became a key support for the unit to construct a realistic battlefield environment, which was suppressed by strong electromagnetic forces from the "enemy", monitored by "enemy" satellites overhead, and attacked by small groups of "enemy agents". These special circumstances are meticulously designed according to the task process and are interrelated. ”The leader of the department introduced that typical scenario tests that may be encountered are pre-set at each stage, from troop maneuvering to occupying positions, from equipment deployment to launch and retreat. It is this highly systematic and fully covered "special situation database" that realistically "loads" multidimensional, overlapping, and coherent battlefield pressures in front of officers and soldiers, making every training feel like being on the battlefield. Soldiers train in the environment where they fight. With the continuous improvement of the ability to construct realistic battlefield environments, the comprehensive expansion of training content, and the deep application of technological means, the military's practical training is constantly advancing in depth. In the air, fighter jets patrol and attack; Cross search of warships at sea; Underwater, submarines quietly lurk... In a naval confrontation training organized by a certain detachment of the Eastern Theater Command, as soon as the Red Fleet entered the designated sea area, high-intensity electromagnetic interference instantly covered the entire fleet, and the command and communication link was almost interrupted. As soon as the red ships emerged from the electromagnetic "fog", the torpedo warning sound of the blue submarine's ambush had already sounded, and the simulated air strike was almost simultaneously launched into the air. A commander from the Red Army exclaimed, "This battlefield environment construction that covers reconnaissance and early warning, command and control, firepower resistance, and other aspects comprehensively tests the combat capability of the troops under extreme pressure." The application of technological means has opened up a new path for constructing high simulation and high confrontation battlefield environments. At a simulation training center of a certain unit of the Southern Theater Command Air Force, as soon as the pilot stepped into the cockpit, he was transported to an altitude of 10000 meters by a highly simulated visual system, engaging in intense fighting between the two sides. The dense anti-aircraft firepower network, strong electromagnetic interference, and mysterious maneuvering trajectories of "enemy" aircraft have appeared one after another, and the engine roar and overload pressure are consistent with the actual flight altitude. From the vast sky to the vast sea, from tangible battlefields to intangible spaces, all officers and soldiers of the army are honing their skills in an environment close to actual combat. At a training ground of a certain brigade of the 82nd Group Army, as soon as the armored vehicle group broke through the obstacle zone, the intelligent target flexibly shifted; As soon as the command for "unmanned aerial vehicle aerial strike" was issued, an invisible "digital ammunition" roared in... Officers and soldiers responded flexibly to the numerous dangers randomly deployed by the intelligent blue army system on the battlefield where reality and virtuality intertwined. Stepping off the training ground, the leader of the brigade said, "The battlefield situation is constantly changing. Only by building a realistic battlefield environment based on complex conditions can officers and soldiers truly enhance their skills
