"The battle system is becoming more and more united, and the combat forces are holding their fingers to form a fist. The actual combat ability is constantly rising, and we have more confidence in defending our country and winning the strong enemy." On the morning of March 5, the first "Delegate Channel" of the third session of the 14th National People's Congress was opened, and Zhang Dongxu, the battalion commander of a brigade of the army, was interviewed by reporters, telling about the development and changes of the transformation and construction of the army. Zhang Dongxu's camp is a heroic unit with outstanding military achievements and heavy honors. During the revolutionary war, it participated in more than 260 battles and emerged with 20 model units and 28 combat heroes. On the day he stepped onto the position of battalion commander, Zhang Dongxu arrived at the honor room and gazed at the battle flags left by his predecessors and the honors earned by the officers and soldiers. He immediately felt a heavy burden on his shoulders. In recent years, this battalion has undergone a transformation from an infantry battalion to a composite battalion, continuously deepening its exploration and practice of practical training. Zhang Dongxu introduced that from the grasslands of northern Xinjiang to the dense forests of southern China, from the coast of the East China Sea to the Gobi Desert in the west, they participated in multiple cross regional military exercises, where officers and soldiers fought against wind, snow, and extreme cold, practicing command, skills, and style. Although the training pace is fast and the preparation tasks are heavy, the officers and soldiers have always been enthusiastic and full of fighting spirit, because everyone feels that every drop of sweat is not in vain, it has condensed into combat effectiveness, "Zhang Dongxu said with emotion. Under the spotlight, Zhang Dongxu recalled a memorable scene from his second year as a battalion commander. That time, he and his comrades participated in collaborative training and carried out low altitude breakthrough missions by helicopter. At that moment, Zhang Dongxu truly felt that the construction of composite forces had been infused with the wings of informatization, and that the combat style had changed from single to joint, from regional to global, giving a feeling of new flight with feathers changing. Zhang Dongxu introduced that in recent years, they have kept up with the pace of updating their weapons and equipment, exploring new growth points in combat effectiveness from advanced equipment and high-tech, and continuously improving their combined combat effectiveness. At the same time, they have participated in cross service joint training multiple times, commanding and coordinating with navy warships and air force fighter jets, and have developed strong combat skills through mutual learning and exchange. Stepping on the land of our motherland, guarding thousands of miles of rivers and mountains, every soldier shoulders a mission Zhang Dongxu said, "I and all the officers and soldiers in the battalion will resolutely obey the Party's command, be determined to strengthen the military and win, comprehensively strengthen military training and preparation, comprehensively improve our ability to win, and spare no effort to fight tough battles, writing a century long struggle for building the military and striving to become a first-class strong military
