The army is a combat team and exists for fighting. If all the work of the army is compared to a circle, then the combat effectiveness is the center of the circle, and all other work must revolve around this center. If we deviate from this center, all construction and work will lose its full significance and value. In this regard, President Xi pointed out vividly and profoundly by analogy, what is the purpose of ensuring that soldiers eat eggs? To ensure that soldiers can better throw grenades. If you eat eggs every day, if the grenade cannot be thrown out in case of war, won't the original intention of eating eggs come to naught? Grenades were thrown well on the battlefield, and it was only by eating eggs that they played a role. This is called the dialectic of eating eggs and throwing grenades. President Xi's dialectics on eating eggs and throwing grenades emphasizes the positioning of combat effectiveness standards and living standards. In the same way, the inspection standards, safety standards and leaders' satisfaction standards must be subject to the combat effectiveness standards. History tells us that if we use the dialectics of "bad eggs" and "grenades", the building of combat effectiveness will take a detour, and we will suffer heavy losses on the battlefield. The work of the armed forces includes all aspects. The dialectics of eating eggs and throwing grenades reflects the fact that all aspects of work should ultimately be conducive to improving combat effectiveness. If we fail to do so, we will be in the opposite direction. The army wants to fight. If it cannot win on the battlefield, everything is zero. In all fields of army building, whether it is an organ or a grass-roots unit, whether it is a combat force or a force charged with scientific research tasks, we must adhere to the standard of combat effectiveness and focus on combat effectiveness. There must not be any speech or behavior that negates the standard of combat effectiveness on the pretext of its own special mission, let alone deviate from the standard of combat effectiveness and engage in another set. "Everything has its purpose, and those who carry it out will succeed." To grasp the work, we should grasp the key points and the key points. The key to handling the dialectical relationship between delicious eggs and grenade throwing is to adhere to the standard of combat effectiveness. Taking combat effectiveness as the standard for testing all the work of the army is the specific application of the dialectical materialist view of taking practice as the only standard for testing truth in the military field. Only by persisting in building with the standard of winning battles, can we take the improvement of combat effectiveness as the starting point and foothold of all construction and continuously improve the army's ability to win battles. If the army is not prepared for war, the country will suffer greatly. Lack of awareness of danger is the deadliest "narcotic" for soldiers. The enemy is not terrible. What is terrible is that we have forgotten our mission to fight and win. One day the military uniform is on the body, one day the battle cannot be forgotten; The moment the steel gun is in hand, it cannot be relaxed for a moment. Whether we can use the dialectics of eating eggs and throwing grenades mainly depends on whether we have a sense of hardship in our hearts and whether we have the concept of enemy sentiment in our minds. At present, the changes of the century and the epidemic situation of the century are interwoven and superimposed, the world has entered a new period of turbulence and change, and the uncertainty and instability of China's security situation have increased. Guard against danger and prepare for peacetime; The most important thing is to practice. Only when the officers and men of the whole army correctly understand and grasp the general trend of China's security and development, enhance their awareness of hardship, crisis and war, put all their minds and energy on war preparation, put war preparation in place, pay close attention to it, sharpen the edge of victory, temper their excellent qualities, and improve their actual combat level, can they achieve the goal of coming at once, being able to fight when they come, and winning when they fight. Using the dialectics of delicious eggs and grenades, it is very important for the commander to demonstrate and drive. If the general is not subtle, the three services will lose their opportunities; If the generals do not give up regularly, the three armies will lose their preparedness; If the general is not strong, the three services will lose their duties. Commanders take the lead in setting up standards for combat effectiveness, regard leading troops to fight and training troops to fight as the top priority, focus all their attention on fighting, and work hard on fighting. Only in this way can officers and men be guided to focus on training and preparing for war. Otherwise, if the top is one inch off, the bottom will be one foot off. At present, an atmosphere of focusing on main responsibilities and businesses and concentrating on war preparation has been formed. The key to further promoting the implementation of combat effectiveness standards is to persevere and implement them. It is necessary to establish the main responsibility of the Party committee, insist on planning and decision-making to reflect the requirements of combat effectiveness development, decide on major issues, give priority to the urgent need of combat effectiveness construction, issue policies and measures, focus on building a joint force of combat effectiveness, and make the standard of combat effectiveness the basic principle of Party committee leadership; We should tighten the responsibility of supervision and oversight, strengthen the enforcement of discipline and accountability, resolutely investigate and deal with acts that damage the building of combat effectiveness, and seriously investigate the responsibility of those directly responsible and the leaders of units; It is necessary to strengthen the implementation of post responsibilities, refine and implement the combat effectiveness standards, clarify the work interface and list responsibilities, regard peacetime and wartime as war positions, and promote the construction of combat effectiveness to make new breakthroughs and achieve new development.
