According to the website "Theater Command" in the United States, at the recent annual meeting of the American Army Association, General Dynamics Land Systems unveiled the concept of a manned/unmanned mobile command center. This concept aims to integrate communication equipment, critical data, and advanced command centers into an armored vehicle, which controls a series of unmanned ground vehicles to jointly advance towards the battlefield. The purpose of introducing this concept is to enhance the flexibility and battlefield survivability of command and control nodes. The US military believes that fixed command centers are easily detected and destroyed by opponents, and will bring significant logistical burdens when following troops. On the other hand, the mobile command and control node can simultaneously control a series of unmanned vehicles and effectively protect the command center and friendly forces. Unmanned vehicles are responsible for direct fire, reconnaissance, air defense, and transportation. According to the above concept, the US Army's "Stryker" armored command vehicle will serve as a "rolling battlefield management node", playing a "front brain" role for friendly forces and acting as a "quarterback" for unmanned ground vehicles (the tactical position of "on-site command" in American football). This kind of "armored ecosystem" with human/unmanned collaboration will be a key development direction for the US Army in the coming years. The introduction of this concept reflects to some extent the current status and trends of the evolution of the US Army's manned/unmanned collaborative combat system. The development of unmanned equipment in the US Army started earlier, with a large number and diverse models, and has formed a relatively complete unmanned equipment system. The US Army attaches great importance to the application of manned/unmanned collaborative technology, and plans to have unmanned systems perform tasks such as reconnaissance, surveillance, target acquisition, firepower strikes, and material transportation. The manned driving platform is mainly responsible for command and control, battlefield evaluation, decision support, etc. At present, the US Army has developed more than 20 models of unmanned ground equipment, including the "Backpack" multi task robot, the "Claw" series robot, the "Scout" series robot, the "Rough Tooth Saw" unmanned tracked vehicle, etc., with a total quantity of nearly 10000 units, which can carry out tasks such as mine clearance and explosive discharge, intelligence reconnaissance, nuclear and biological monitoring, fire support, logistics support, patrol and duty. In recent years, while upgrading existing equipment, the US Army has also launched new research and development projects including "next-generation tanks" and AML unmanned rocket launchers. The development of unmanned ground equipment in the US Army has shown the following trends: the platform has a wider range of applications and is suitable for more mission areas; Pay attention to improving the degree of autonomy and situational awareness of unmanned combat platforms; Emphasis should be placed on enhancing the firepower and long-range precision strike capabilities of unmanned equipment, shifting it from "auxiliary warfare" to "main warfare". Some comments suggest that the current level of intelligence in unmanned systems is limited and cannot completely replace human thinking and judgment. Therefore, in the near future and for a considerable period of time in the future, the US Army will adopt a manned/unmanned system collaborative combat approach. Correspondingly, the concept of manned/unmanned mobile command centers will be more widely adopted and applied. However, with the continuous development of related technologies, the application of unmanned systems in combat will become increasingly widespread and may become a new type of combat force that cannot be ignored in future wars. At present, the US Army has begun evaluating the establishment of unmanned combat vehicle platoons and plans to start building company and battalion level unmanned combat vehicle units in the next two years, ultimately creating an integrated land air unmanned combat unit. To this end, the US Army will increase its efforts to develop more unmanned equipment to replace humans in completing the vast majority of complex combat tasks. With the increasing proportion of unmanned elements, the command structure of the US Army will also be adjusted, and the relevant trends are worthy of continuous attention. (New Society)
