(missile assault. Provided by the author) in the depth of the valley, a certain conventional missile unit quietly arrayed to conduct a day and night firepower assault drill; In the vast desert, a certain strategic missile unit galloped forward and backward to launch training under extreme conditions; Deep in the dense forest, a cruise missile unit meanders through and carries out continuous operations of multiple subjects... Different longitude and latitude coordinates and different ballistic trajectories outline the magnificent "sharpening sword map" of the rocket force, showing the capability dimension of the new-type big power sword. In the past 10 years of strengthening the army, the rocket army has upgraded its weapons and equipment, pressed the "fast forward" button to build its combat effectiveness, and stepped out of the "acceleration". Since the 18th National Congress of the Communist Party of China, President Xi has taken a long-term view, personally planned and promoted the construction of strategic forces, and mapped out a new blueprint for the development of the rocket army. From the leapfrog transformation of the Second Artillery Corps to the rocket army, from the earnest request of "absolute loyalty, absolute purity, and absolute reliability" to the sonorous command of "striving to build a powerful modern rocket army"... The vast number of officers and men of the rocket army listen to the orders and follow the strategic requirements of "both nuclear and normal forces and global deterrence war" and the core standards of "being able to fight at any time, launch on time, and damage effectively", We will advance toward the goal of building a world-class strategic service. The grand military parade ground in the new era witnessed the sonorous pace of the transformation and development of the missile array. In the Victory Day parade in 2015, more than half of the missile arrays walking with their heads held high made their first appearance at the parade; In 2017, Zhu rihe held a military parade on the battlefield, and the type 5 missiles that had been tempered by actual combat formed a strategic strike group, demonstrating the strong military style of the strategic services with a powerful lineup; In 2019, the 70th anniversary of the National Day parade, dongfeng-17, changjian-100 and dongfeng-41 missiles unveiled the "mysterious veil" for the first time, showing the strong strategic balance ability of "trump card" and "bottom card". A strong country must have a strong army, and a strong army must be a sharp weapon. With the increasing strength of China's comprehensive national strength and the substantial improvement of its scientific and technological level, new missiles are continuously listed, and the "Dongfeng family" is flourishing. The rocket army has initially formed a combat force system with both nuclear and conventional weapons, matching models, range convergence, and diversified strike efficiency. Whether it is a precision knife or a strategic weapon, its comprehensive performance is more and more stable, the degree of informatization is higher and higher, the anti-jamming ability is stronger and the damage power is greater and greater. Walking into old-fashioned missile brigades and visiting new and cutting-edge divisions promoted by the spring breeze of building a strong army, the reconstructed weapon and equipment system is promoting new changes in construction mode, command style and training mode. The evaluation of the missile brigade commander competition of the rocket army is one volume for each brigade, pointing directly at the battlefield. The rocket army's series of exercises and training activities have been constantly "expanded and upgraded". One missile force after another has been hardened and trained, and batch after batch of "great power sword skills" have been successively produced. China's strategic iron fist is getting tighter and harder. "Fire!" On the fiery military training ground, as a young trumpeter pressed the launch button, the long sword soared to the sky, marking a brilliant trajectory. In the new era, from "fixed launch" to "mobile launch", from "opportunistic launch" to "random launch", and from "live ammunition launch" to "real combat launch", the new missile array has made a lot of tracks and loud noises, which are exactly the answers of the rocket officers and soldiers to build a strong army with their actual actions.
