Focus on the main responsibility and business ■ Gao Bin President Xi pointed out that "maintaining concentration, enhancing confidence and concentrating on running our own affairs are the key to coping with various risks and challenges". For our army, to implement this important exposition, we should have a sense of responsibility of "always being at ease" and concentrate on doing our main tasks. If you are well prepared for training, you should be ready for military affairs. The core function of our army is to fight. The fundamental direction of all construction and work is combat effectiveness. The main responsibility and main business of every soldier is to prepare for war. If we deviate from this fundamental direction and from this main responsibility, the standard of combat effectiveness will be weakened and the role of combatants will be misplaced. Only by focusing on the main task and firmly establishing the standard of combat effectiveness can we continue the glory of "from victory to victory". At present, a century of changes and a century of epidemics are intertwined and superimposed. China is facing a more severe national security situation, and there is an urgent need for our army to comprehensively improve its combat readiness. Today, we have more means and choices to safeguard national security, but military means have always been the means to ensure the minimum. We must, with the sense of urgency that time waits for no man and seize the day, do our main job well and enhance our strength to win. Only in this way can we have sufficient confidence and a firm backbone. The most important thing to do a good job is to eliminate interference and devote yourself to practical training. Only by firmly establishing the idea of a combat team, always keeping a clear mind that "war is not far away", focusing on the changes in science and technology, war and opponents, and focusing on fighting and working hard in all aspects of work, can the officers and men acquire the excellent ability to defeat the enemy and truly fulfill their mission and trust.
