UAV low-altitude reconnaissance in the sky; In the dense forest, the reconnaissance team approaches and cuts through; On the mountain road, the reconnaissance vehicle radar operates at high speed... In the early spring, a full-fledged, all-element red-blue combat drill of a brigade of the 71st Group Army opened. Ni Rui, the battalion commander of the Red Artillery Battalion, organized the reconnaissance team to go forward and conduct multi-dimensional and multi-domain intelligence detection on the Blue side. In a short time, the information data such as the coordinates of the blue position and the force formation will be transmitted back to the battalion command post through the radio stations at all levels and the special command network. "The Blue Artillery Unit will pass through a certain area." After receiving the real-time information shared by the reconnaissance unit, Sun Yihui, the operator on duty, immediately marked the Blue Artillery Unit data on the electronic sand table. After that, Ni Rui opened the battlefield database to analyze the situation: "The blue towed artillery has a far range than our artillery, and can pay real-time attention to the blue side's dynamics to avoid being hit by artillery fire; our artillery is more mobile than the other side, and has a wide range of fire coverage, so we can take the tactics of quick fight and quick withdrawal, and quickly move the position after accurately striking the blue side." Ni Rui immediately made up his mind, and the officers and soldiers moved at the command, and worked hard to prepare. In a short time, the artillery shells came out of the chamber, and the Red Army officers and soldiers quickly moved their positions after completing the precise strike. "To achieve the maximum damage to the enemy with the minimum firepower, the key is to cultivate the data thinking ability of the commander. Only by fully mastering and flexibly calculating, analyzing and using the data can the commander make accurate decisions and better grasp the battlefield initiative." Ni Rui told reporters that this profound understanding of the battlefield data originated from a previous confrontation drill. At that time, the battalion fought with a heavy synthetic force with new equipment, during which the battalion's equipment was judged as "war damage" one after another. "Move the position!" The commander organizes the troops to move according to his experience. As expected, during the transfer process, many guns were still "destroyed". On the first day of the confrontation, the camp ended hastily with heavy losses. In this regard, Ni Rui fell into meditation. He later learned that before the war, the enemy had carried out long-endurance, large-depth and all-directional reconnaissance of the battlefield through multiple UAVs and portable reconnaissance equipment, mastered the distribution of important targets of the battalion, and generated a real-time three-dimensional map of the battlefield through military modeling technology. After the battle was launched, the battalion was eager to attack after receiving the target information from the front scout. The enemy used the known data to deduce the position of the battalion's position, and predicted the next action of the battalion through the three-dimensional map of the battlefield. "The drill is not only to distinguish between victory and defeat, but also to find out their own shortcomings, learn from the advanced experience of the opponent, and constantly improve and improve." The brigade leader pointed out pointedly at the review summary meeting that the loss of the battalion was due to the commander's reliance on experience and intuition in the battle decision-making, and the lack of awareness of using data to make decisions and relying on data to fight, "Only by focusing on strengthening data thinking in peacetime and cultivating the good habit of organizing and planning operations with data, can we accurately use our troops in wartime and have a better chance of winning." To this end, the brigade drew inferences from one instance and made in-depth investigation, taking a series of measures to strengthen the ability of commanders at all levels to obtain, analyze and use data. In practice, they promote the integration of military modeling technology into the whole process of military operations, and improve the reliability of reconnaissance data by using image comparison, direct calculation and other methods
