The fire net is thick, and the armor is running. At the foot of Yanshan Mountain, on the training ground of a brigade of the 81st Army Group, a comprehensive practical drill was in full swing. The battle entered a stalemate, and the officers and soldiers of the "Meritorious Officer" tank company volunteered to attack. They drove the domestic 99A main battle tank, braved the "enemy" intensive fire and launched a charge, just like a sharp knife to cut through the "enemy"'s solid front defense, and straight into the "enemy"'s depth, opening up a way for the army to attack. During the confrontation drill, the officers and soldiers of the company sat around and talked about the story behind the "Meritorious Officer" tank, which was very exciting. The "meritorious minister" tank is the first tank in the history of our army. After five generations of upgrading, compared with the 59 type tanks in the past, the 99A type main battle tank has all-weather precision attack capability, and can achieve battlefield awareness, situation sharing, coordinated attack and defense and other operational effectiveness, so that officers and soldiers can "be more steel and more gas" and have more confidence to win. "As the successor of the meritorious company, we should step up the use of new weapons and equipment, and transform scientific and technological advantages into winning advantages." Li Zhijun, the driver of the "Meritorious Officer", said, "This is also the practical action of a heroic army officers and soldiers to welcome the 20th CPC National Congress." The process of transformation is like rebirth in a bath of fire. If we say that to march to the information highland, others start with a 100 meter dash, but Li Zhijun is crawling and climbing, "feeling like a 'most familiar stranger' when touching new equipment". In 2017, shortly after the 99A main battle tank was assembled, the company organized a real vehicle driving training. The tank driven by Li Zhijun stalled on the way due to improper operation and delayed the aircraft, so the final assessment result was the bottom. Science and technology strengthen the military, "strong" is not only the equipment, but also the concept. In the opinion of this "ace driver" with decades of experience, what he needs to break most is the "heart block". "When you enter the information age, your thinking cannot stop in mechanization." Li Zhijun understands that the transformation and upgrading of the army is not as simple as "two legs are replaced by four wheels". Behind the various touch buttons on new equipment, it reflects the change of operational thinking and the reshaping of personal capabilities. During that period, the cadres and backbones of the company took the lead in entering the chariot and the battle position, and studied the information equipment diligently... Half a year later, the officers and soldiers of the company were familiar with the parameters of tank parts, and many companies sent people to learn from them. With a thorough understanding of the new equipment, the officers and soldiers of the "Meritorious Officer" tank company realized that to give full play to the power of the new equipment, they could not adapt to the future battlefield by fighting alone. "How can the new tank company maximize its combat effectiveness in joint operations? How can we accelerate the transformation of advanced technology into combat effectiveness?" The sense of urgency from the future battlefield forced the officers and soldiers of the "Meritorious Man" tank company to keep raising the question mark. On the one hand, while exploring and training, they explored the force formation, command and liaison methods and fire coordination procedures for the new tank company to perform tasks under the composite system; On the other hand, they carried out mass scientific and technological innovation activities to stimulate grassroots officers and soldiers to innovate and study the methods of warfare and discipline according to the operational needs, and it became a common practice to learn, drill and use science and technology. Not long ago, there were many highlights on the field training ground in Northern China: multi arms coordinated stereoscopic attack, precision destruction with combination of shells and guns, and joint victory with integration of information and fire
