There are many reasons why Su Yu, the "always victorious general", won battles, such as "there are always strange plans and daring to make strange troops", "resourceful and decisive, and wise people", and "he can always seize the opportunity to turn the situation around", and so on. General Wang Bicheng, who has long been a subordinate of Su Yu, stated another reason why Su Yu can win battles: "He has always asked the troops to prepare for war according to the requirement of fighting immediately. He commanded us to win battles because we do not fight uncertain battles." This is true. One day in 1946, Su Yu, who was inspecting the preparation of a certain unit, became angry when he heard the commander's words, "Anyway, it's not urgent, we'll replenish the ammunition in a few days." He said, "In a few days? Not in half a day! We must prepare for war immediately." Su Yu kept a tight and solid grip on preparing for war and repeatedly emphasized that "preparing for war must not wait, the sooner the better, the faster the better, the finer the better." The way to win is careful. Fighting is both better than playing on the spot and preparing for battle. Adequate pre war preparations provide reliable support for on-the-spot performance. "If the soldiers are not prepared before going to the battlefield, the missing materials are not replenished in a timely manner, and they are unclear to the enemy and friendly forces," no matter how well they play on the spot, they may not win the battle. ". The history of war warns us that "if troops are not prepared beforehand," there will be a domino effect of "not being killed," "losing the opportunity," "being late in the event," and "not winning but the army collapses," causing irreparable losses. However, in reality, there are still individual units that do not achieve "immediate" combat readiness. The work that should have been actively carried out has become "wait and see", the construction that should have been carried out as planned has become "slow and then work", the difficult problems that should have been solved quickly have become "let go and then look", and the remaining problems that should have been solved quickly have become "delay and then discuss"... All these things, in the final analysis, are the weakening of the sense of hardship, the weakening of the sense of mission, and the weakening of the sense of war. To win tomorrow's war, one must be prepared for today. Especially in modern warfare, "the first battle is the decisive battle, and the discovery is the destruction". The outbreak is sudden, the process is short, and the warning time is extremely short or even there is no warning. Daily combat readiness level is often a key factor affecting the outcome of the war. Only by being well prepared can we win the initiative and plan for victory; If you are not prepared, it is inevitable that you will be led by the enemy's nose, and even end up being defeated and doomed. "Ready to fight at any time" is by no means a simple slogan, but it should be implemented in action. All units should focus on all preparations for military struggle, always focusing on "emergencies", setting examination questions based on "response", and improving the "proactive" preparation model. It is necessary to do a good job in daily combat readiness work from a strategic perspective, further tighten the combat readiness system, strengthen combat readiness duty, carry out combat readiness drills, comprehensively improve the level of combat readiness, and ensure that troops can come as soon as they are called, fight as they come, and win in battle.
