In recent years, with the continuous improvement of the level of practical training in the military, "seeking combat effectiveness from data" has become a consensus among officers and soldiers. Analyze combat data and enhance firepower damage effectiveness; Establish a 'data archive' to fully utilize the performance of missiles; The introduction of "data assistants" and scientific group training and teaching... These beneficial explorations from the stationed training ground are vivid epitomes of the transformation of military combat effectiveness construction from "extensive and experiential" to "refined and specialized". Looking back at military history, war and data always go hand in hand. From the "temple calculation" in Sun Tzu's "The Art of War" to Comrade Su Yu's statement that "fighting is mathematics", the use of data has always been the underlying logic for winning the battlefield. In the era of information warfare, the ability to utilize data becomes even more important. A set of data may affect a strategic decision, even the outcome of a war or the safety of a military unit. Data has become the fundamental support for the overall operation of the combat system based on information systems. Whoever is good at digging deep into this powerful mine of data can gain a competitive advantage on the battlefield. Resident training is the "golden period" for troops to hone their practical combat capabilities and improve their ability to win. From individual weapon range data to team tactical coordination parameters, from equipment performance limits to battlefield environment variables, each unit should take advantage of the training opportunity to establish a standardized data collection process, build a combat database, refine and analyze massive training data, and integrate more training data that can withstand practical testing to assist battlefield decision-making and improve combat plans. At the same time, we should continue to cultivate the data "sensitivity" of officers and soldiers, make good use of data resources to solve practical problems, and strive to master the key to unlocking the door to victory, so that data can truly become a "booster" to enhance the combat effectiveness of the troops.
