Studying these wars is of special significance to accurately grasp the development trend and future trend of the new military revolution, actively promote the military revolution with China characteristics, and make good preparations for military struggle. Since 1990s, the world's new military revolution has moved from spontaneity to consciousness. It can be said that although the Gulf War still has many characteristics of mechanized warfare, it has begun to show the dawn of information warfare. The wars in Kosovo and Afghanistan have tested the achievements of the new military revolution again and again, leaving a footprint of stepping into the information war step by step. This year's Iraq war further shows a historic leap to information warfare. It shows the world an information warfare supported by Skynet and information umbrella, led by information and intelligence, aimed at controlling the opponent's spirit and will, and assisted by precision strike. Information has risen from "the auxiliary position of helping to make plans" to the dominant position of guiding the operational process and establishing operational objectives ",which indicates that the new war form is maturing. The form of war refers to the overall appearance of war, which consists of main battle weapons, army formation, operational ideas, operational methods and other war elements. Among them, the main battle weapon determines the formation of the army, the change of operational thinking and mode, and thus produces different war forms. When information weapons and equipment are widely used and become the leading force on the battlefield, it marks that human society has entered the era of information war after experiencing unarmed combat, cold weapon war, hot weapon war and mechanized war. Only 8% of informationized ammunition was used in the Gulf War, 35% in the Kosovo War, about 56% in the Afghanistan War and more than 90% in the Iraq War. Information weapons and equipment account for more than 70% of its total equipment. The new military revolution will continue to occur, and it will take a long time for the information war to mature. It is still difficult to accurately predict and grasp what the future army will look like under the existing conditions. However, some homosexual features in recent local wars have opened a visual window for the future information war, allowing us to look forward to the future general trend and provide reference for us to promote the military reform with China characteristics today. For example, the traditional concept of war will be broken, and peacetime and wartime, strategy and tactics, soft warfare and hard warfare are intertwined, and the boundaries are increasingly blurred; Battlefield spaces overlap each other, showing full-dimensional characteristics, and cyberspace, psychological space and outer space will become the main battlefields of the warring parties; The boundary between the main force of war and the military service is increasingly blurred, showing the characteristics of miniaturization, lightweight, integration, intelligence and digitalization; The modes of engagement are asymmetric, nonlinear, over-the-horizon and non-contact. After the test of the Iraq war, the mechanized war has evolved into an information war, and the pace of the transformation from the mechanized army to the information army has been further accelerated. In the 1990s, the military reform focused on improving the combat capability of the mechanized army and strengthened its structure. In 2 1 century, military reform played a role in "deconstructing" mechanized troops. In other words, information technology is not simply embedded in the mechanized platform, but is "reorganized" in the process of informationization. In the past, it was conducive to the rapid flow of information, but today, more attention is paid to how to keep up with the rapid flow of information to reshape the structure of the army, promote, transform and reorganize mechanization through informationization, seek functions through structure, and redesign the construction objectives of the informationized army with a brand-new concept. In fact, it is also the case. Just after the end of the Iraq war, the US military implemented a "slimming" plan for its only digital reloading machine, step 4 Division. They think that the fourth digital division is too big to meet the requirements of the next war. The transformation of the army needs a process. Judging from the current trend of new military reform, the development focus of the army is informatization, missile, aviation, special warfare and diversification. The development focus of strategic missile forces is to shorten the launch preparation time, have the ability of mobile strike and real-time strike, and improve deterrence. The development of the Air Force focuses on celestial forces, satellite attack systems, unmanned aerial vehicles and early warning capabilities. The development of the navy has surpassed the era of aircraft carriers, focusing on underwater development, such as nuclear submarines (ships), underwater smart mines and sea-based sensors. Information warfare troops, psychological warfare troops, camouflage deception troops, etc. , will become increasingly prominent. Looking ahead, the service will be "reorganized" according to its functions. It should be pointed out that to understand and grasp the war forms and army building in the transitional period, we should learn to use the positions, viewpoints and methods of dialectical materialism and historical materialism, and examine each local war with a linked and developmental perspective to avoid the wrong tendency of seeing the forest for the trees. After the Gulf War, the argument of winning by precision strike was once high. After the wars in Kosovo and Afghanistan, some people put forward the army's "outdated theory" and the army's "extinction theory". The Iraq war made the status of the army rise again. However, when the world re-emphasized the position and role of the army, the US military began an all-round transformation. Times are developing too fast. Studying the evolution of war and planning army building need to look further into the future. There are many more.
