In the coastal shoals, a joint logistics support and support exercise under the information-based conditions was carried out with great enthusiasm; On the snowy plateau, a field support and support drill with all personnel, equipment and elements was launched; In Baishan and Heishui, a drill to test the troops' actual combat support capability of "loading, unloading, moving, attacking, repairing, rescuing and defending" is in full swing... Different drill tasks in different places reflect the goal of support to win, and reflect the new leap of our army's new joint logistics support system to support joint operations. To build a world-class army, we need to build a first-class joint logistics support system that is compatible with it. Since the 18th National Congress of the Communist Party of China, President Xi has attached great importance to and placed great hopes on the logistics work of the army, and made a series of important instructions and major strategic decisions around the construction of modern logistics. At the inaugural meeting of the joint logistics support force of the Central Military Commission, President Xi Jinping awarded a military flag to the joint logistics support force and delivered a lecture, clearly proposing to strive to build a strong modern joint logistics support force. The joint logistics support forces should keep in mind the trust and strive to advance. They should take key steps on the road to victory in joint operations, joint training and joint support, and actively build a new joint logistics support system that meets the needs of winning an information-based war. In line with the reform of combat forces, our army has formed a joint logistics support system with our army's characteristics, with the joint logistics units as the backbone, the logistics of various services as the supplement, the integration of integration and division, and the general and special lines. Since the establishment system adjustment, the joint logistics support force of our army has accelerated its integration into the joint operation system, stepped up practical training, accelerated the improvement of integrated joint support capability, and constantly promoted the same frequency resonance and efficient coupling of joint logistics support and joint operation. Leaders of the joint logistics support units told reporters that in recent years, they have accelerated the building of military logistics chains, joint delivery chains, and battlefield rescue chains, focused on improving joint support capabilities, organized mobile support forces to integrate into joint exercises and joint training of various theaters and services and arms, and one support team participated in the whole process and honed its support skills. The military logistics chain is continuously connected. The joint logistics support forces at all levels have integrated logistics forces and resources across the military, the military, and the arms, unblocked the links such as the financing, storage, transportation, distribution, and recovery of combat readiness materials, and realized the efficient support of various professional materials. In 2019, a storage and supply base introduced local advanced logistics technology and equipment to build a large-scale, comprehensive and intensive military logistics hub; In 2020, a comprehensive warehouse built a material database to realize the labeling management and networking link of stacked materials. The material management can be linked and dynamically visible at any time. The military logistics chain "goes through needles and leads", and the support forces at all levels "grasp their fingers and become fists". On the plateau with an altitude of more than 4200 meters, the support department of the Xinjiang Military Region will directly "express" the equipment and materials from the warehouse to the front line of the exercise and training; In the hinterland of the Central Plains, a brigade of the army has established a local transportation mechanism for military equipment, which has effectively widened the delivery route for heavy equipment. The joint delivery chain is rapidly taking shape. From the accurate transportation of equipment and materials to the rapid delivery of combat forces, from the three-dimensional advance of commanders and fighters to the emergency evacuation of the wounded and sick, the effectiveness of joint delivery has gradually become apparent. A dispatch center in the Western Theater has set up a three-dimensional delivery command post in conjunction with the theater, the transportation departments of the services and arms, and the local transportation and combat readiness departments to comprehensively use the organizational transport capacity of the units and the local civilian transport capacity to provide delivery support; A dispatch center in the southern theater passes through highways, waterways, railways
