Adhere to building a joint force to win - a series of talks on "realizing a strong military road in ten years and welcoming the 20th CPC National Congress"; Long range rockets spray flames, forming a dense fire network in the air; The drone sends back the attack image in real time... A large number of new combat forces appeared in the training ground, effectively testing the integrated joint combat capability of the army, which shows that our army is fully determined and capable of maintaining the reunification of the motherland and safeguarding national sovereignty and territorial integrity. President Xi pointed out that we should promote the accelerated development and integrated development of new combat forces, increase efforts to replace birds with cages, and strive to build a military force system with elite combat forces as the main body. The new combat force is a wind vane of military development in an era, representing the development trend of military technology and combat methods, and a new growth point of combat effectiveness. Every military revolution in history has originated from new combat forces. New types of combat forces are often actors of wonderful war dramas, breakers of difficult impasses, and creators of brilliant miracles. Whoever can take a step ahead in the development of new combat forces will win the first chance. Otherwise, the opportunity will be missed and a new gap will be opened. Soldiers are not many but good. The key to fighting with refined troops and winning with precision lies in the word "refined". In line with this, new changes are taking place in the size, structure and strength of the military, with more and more prominent features such as streamlining, integration, miniaturization, modularization and versatility. Before this round of reform, the total number and scale of our army were somewhat large, the major proportion was not reasonable, the elite combat force was relatively small, and the combat capability of the system needed to be improved. Through the reform of scale, structure and strength composition, we have significantly reduced the traditional arms and old equipment forces, enriched and strengthened new combat forces, and increased the proportion of new quality combat effectiveness. The internal force structure of the services and arms has been optimized. What has been reduced is "fat", what has been strengthened is "bone", and what has been strengthened is "internal skill". Our army has become more capable, more optimized in structure, and more scientific in organization. It has taken a big step in the transformation from a quantity and scale type to a quality and efficiency type, and from a manpower intensive type to a science and technology intensive type. The army's organization has developed in the direction of enrichment, synthesis, versatility, and flexibility. "Victory smiles at those who can foresee changes in the characteristics of war, not at those who wait for changes in the war to adapt." Significant changes have taken place in the space-time characteristics and winning mechanism of modern wars, and the characteristics of using elite forces to carry out precision operations are more prominent. In the Nagorny Karabakh conflict two years ago, Azerbaijan used drones, a new type of combat force, to carry out precision strikes against Armenia, and achieved unexpected results. With the accelerated development of the new military revolution in the world, all major countries have taken the development of new combat forces as an important support to lead the force system. Through the establishment of the air and sky army, network forces, unmanned combat forces, etc., they have worked hard to create a "new engine" to promote the overall leap of combat effectiveness, and a "new lever" to win the balance. Modern war is about systems and elites. The system is the "behind the scenes force" of elite soldiers, and elite soldiers are the "discharge tip" of the system.
