"In Journey to the West, Sun Wukong holds a golden cudgel in his hand and relies on his seventy-two changes to subdue all the demons and ghosts on the way. As soldiers, we also need to have the ability to wield the 'eighteen weapons' and' seventy-two changes' in our hands to defeat each opponent in the future battlefield." This metaphor by a military leader is thought-provoking. Speaking of "seventy two changes" in the weapons in hand, one cannot help but think of the anti Japanese hero Zhao Zhangcheng. At that time, due to the lack of heavy weapons in the Eighth Route Army, the Japanese army built a large number of blockhouses around our base area in an attempt to trap our anti Japanese troops and civilians. To this end, the head of the Eighth Route Army of the Taihang Military Region at the time instructed Zhao Zhangcheng to explore the tactics of using mortars to shoot down blockhouses in order to break the Japanese blockade. As is well known, mortars are curved firing weapons that mainly deal with infantry groups, making it difficult to strike a single target with flat fire. However, after many experiments, Zhao Zhangcheng finally successfully converted the mortar into a flat curved two shot gun, and vigorously promoted it in the battlefield. Our military has repeatedly destroyed enemy strongholds. "People often say, 'What kind of weapons are there to fight what kind of war', but there is also a saying that 'the same weapons fight different wars'.". Compared to the two, the former emphasizes objective factors, while the latter has more innovative characteristics. For any weapon equipment, if the factors of its transformation and utilization are taken into account, it will display an obvious main function and several potential secondary functions. The average person usually only pays attention to its main function, while it is easy to ignore its secondary function. For those commanders who are flexible, imaginative, and innovative, they will never regard the main function of a weapon as the only function, and the customary usage as the only usage. In an emergency, they will use their existing weapons and equipment to fight different battles, as Zhao Zhangcheng did. With the rapid development of military science and technology, especially emerging technologies, modern warfare is becoming more and more joint and hybrid, and the use of weapons and equipment is also increasingly developing in the direction of relevance and intelligence. Seeking to find or create a "ultimate weapon" or "universal weapon" is neither realistic nor possible. The only way to achieve victory is to refine and reorganize the "18 weapons" in your hand and use the "72 changes" in use to cope with the unpredictable battlefield. War practice also shows that those who are good at "combining" win, and those who are good at "changing" win. Who can effectively combine and integrate weapons and equipment in their hands, and then deduce infinitely variable and diverse fighting methods, who can win the initiative in the battlefield. In recent years, a large number of new weapons and equipment have been installed in the army, which is a good thing, but there are still some problems in practical application. For example, some are only satisfied with being able to fight and operate, but there is still a long way to go in terms of how to maximize the power and potential of weapons and equipment, and how to maximize technical and tactical performance; Some are not able to use them effectively and are often affected by "functional immobility". They use weapons and equipment in a disciplined manner, and lack the effort to use strange strategies, methods, and tricks; "Some units are not well connected, and the firepower systems of various services and arms tend to be stylized and simplified. Although weapons and equipment are becoming increasingly diverse, their usage and tactics are always fixed on a certain routine.". "All these things may be perceived and understood by my opponents on the battlefield, causing me to fall into a passive position.". From one
