"Multi-Domain Operations" Theory，After the theories of "Air-Land Battle" and "Air-Sea Battle"，The latest joint bet365 games theory proposed by the US military。In 2014, the US military first proposed the concept of "multi-domain warfare" in the "Army Operational Concept 2020-2040: Winning in a Complex World"，The US military elaborated on its concept at the 2016 Army Association annual meeting，Written it into Army bet365 games doctrine，Publish white paper，And renamed it "Multi-Domain Operations" at the end of 2018。During the Navy、The Air Force responded one after another，Establishment of experimental unit，And organized live-fire exercises。Just a few years，From the introduction of the "Multi-domain Operations" theory to the entry into live-fire exercises，Developed rapidly，The reason，Mainly because its operational concept meets the needs of joint operations，Able to lead and integrate the construction and use of US military forces at a higher level。

　　Proposed based on tasks and own bet365 games

From the U.S. military’s proposal of “Air-Land Battle” in 1973 to the “Air-Sea Battle” theory in 2009，After more than 30 years。But it is proposed from the theory of "Air-Sea Battle"，To the emergence of the "multi-domain bet365 games" theory，Only a few years，During this period, "Air-Sea Battle" was also renamed as the joint concept of "entering and maneuvering in the global commons"。“Multi-domain bet365 games” is the latest joint bet365 games theory of the US military，Their emergence and development，There are many factors。

First, the needs of army development。100 hours of ground bet365 games from the Gulf War，No ground bet365 games troops have been deployed in the 78-day Kosovo War，From non-contact theory to non-linear bet365 games theory，The Army’s status and participation in bet365 games continues to decrease。As the strategic focus of the United States shifts from the war on terrorism to competition and confrontation among major powers，The U.S. Army is in danger of being marginalized。Especially the sea、The Air Force lost no time in proposing the concept of "Air-Sea Battle"，will take the lead in the development of operational concepts、Planning、Equipment research and development and various experimental exercises and other important tasks，Promote defense budget and policy to favor the navy and air force，Resulting in Army construction budget cuts、The dilemma of staff reductions，The bet365 games status is gradually declining。In order to complete self-rescue，The Army and Marine Corps jointly proposed the "Multi-domain Operations" theory，Strengthen the status and role in bet365 games，At the same time, we also strive for an extra piece of the national defense budget for our own construction and development。

The second is the need for task adjustment。Whether it is the "Asia-Pacific rebalancing" strategy during the Obama administration，It is still the “Indo-Pacific Strategy” during Trump’s administration，The United States has shifted its main security threat from terrorism to competition and confrontation among major powers。In Afghanistan、The bet365 games theory that achieved great success in the Iraq War，With the change of bet365 games opponents，We will also face a situation where it will be difficult to compete in future operations。Whether it is the war in Afghanistan or the war in Iraq，The strength of its bet365 games opponents is relatively weak，The US military can use its information、Equipment Advantages，Quickly seize information control and air control，Thus achieving bet365 games victory。But the opponent we face now，Their weapons and equipment、Information Technology、Network technology is something that previous bet365 games opponents did not have，And it is developing and has equipped stealth aircraft、Advanced weapons including new hypersonic weapons，It is constantly weakening the advantages of the US military。Military strength of great powers，Make the US military realize that it is difficult to achieve absolute superiority in the sea and air fields，To gain control of the war，This is also the theory of "multi-domain operations" proposed by the Army and Marine Corps，Get air force quickly、Reasons for the Navy’s positive response。And the conflict in Ukraine in 2014，Ukrainian pro-Russian armed forces without an air force，Acquire air superiority through ground bet365 games forces，Comprehensive use of electronic warfare、Cyber ​​Warfare、Self-service system、Drones, etc.，Defeat massive ground forces，Leaved a deep impression on the US military，Make the US military further aware，To survive and maintain superiority one must look at all areas of warfare。

　　“Multi-domain bet365 games” focus on synchronized coordination and linkage

"Multi-domain operations" is to break the boundaries of various services and operational responsibility areas，Use force units from other fields in a certain bet365 games field，Especially changing the role of “assistance object” in Army operations，Play its role in joint operations。Simultaneously achieve synchronous coordination and linkage of firepower and maneuverability in the entire space domain，Form an advantage over the enemy。

First, give full play to the role of the Army in cross-domain operations。“Multi-domain operations” concept requirements，All services must not only have capabilities in traditional bet365 games fields，There is also a need to make a difference in other areas。What is more emphasized here is the Army’s cross-domain capabilities，Because no matter it is the Gulf War、Iraq War，It’s still the anti-terrorism operation in Afghanistan，The Army and Marine Corps have been fighting、Play the role of "assistance object" in the operation。Due to the limited military strength of the bet365 games opponent，US military air superiority、Information advantages can be brought into full play。But we will encounter high-end opponents in future battles，Support from other services may be blocked or difficult to play。So the Army must assume its role in joint operations，Not only must have the ability to independently perform a variety of bet365 games missions，There is a greater need to utilize reliable forward bases and rich battlefield information，And its own cross-domain perception、Target identification and strike capabilities，Commitment、Ability to support operations in other areas，Even the ability to lead actions in other fields。For example, coordination and integration of joint bet365 games forces，Participate in offshore operations、Sea Control、Strategic shipping and other tasks；Use electronic warfare、Cyber ​​Warfare、Combined operations using drones and other comprehensive means，Participate、Support and even control other bet365 games domains。

The second is to emphasize coordinated actions in the bet365 games domain。Joint operations for the future，What Admiral Harry Harris, Commander of the U.S. Pacific Command said，“We need to be united to the point where no one service is dominant，No field has fixed boundaries”。And the requirements of "multi-domain operations"，As Harry Harris said，“Multi-domain operations” breaks the boundaries of traditional bet365 games domains with military services as the core，From the coordination within the geographical space that originally belongs to the specific scope of each military service，Turn to the integrated application of the bet365 games capabilities of all services in the shared space field，Focus on coordinated actions in the bet365 games domain，Emphasis on the integration of various capabilities in various fields，No longer pay attention to military attributes。In "Multi-Domain Operations"，Joint commanders must adapt traditional collaborative thinking，Change to a way of thinking that takes multi-domain bet365 games capabilities as the collaborative object，Need to shape the battlefield space that includes all bet365 games domains，Synchronized and coordinated joint bet365 games force operations，Comprehensive use of various bet365 games capabilities，In order to create and take advantage of fleeting bet365 games opportunities in one or more bet365 games domains，Weaken the opponent’s bet365 games capabilities in multiple domains。

　　Aims to expand cross-domain joint action bet365 games

The initial goal of the "multi-domain bet365 games" concept is to realize the U.S. Army's transition from traditional land to sea、Extended capabilities in areas such as air and network，The ultimate goal is to fully integrate all services，Expand the scope of bet365 games of various military services。Based on this understanding，To achieve the goal of "multi-domain bet365 games"，The US military needs to update existing equipment、Adjust the establishment，To meet the needs of "multi-domain bet365 games"。

First, speed up the research and development of technical equipment。Concept of “Multi-Domain Operations”，Requesting to play a cross-domain strike role，The military service cannot focus on its own service field，Must provide the same capabilities as other services in other areas。So the Army must not only play a decisive role in ground battlefield operations，It should also be able to intercept missiles、Sink the enemy ship、Suppress satellite，Even invading or destroying the enemy's command and control system, etc.。For this，The Army wants to expand long-range precision strikes、Detection, identification and surveillance aircraft、Cruise missile、Ballistic missile capabilities，So in the "Warfighter Science and Technology Requirements" report released by the U.S. Army Training and Doctrine Command in 2016，Determine the focus on developing vertical take-off and landing aircraft、Cross-domain firepower、bet365 games Vehicle、Advanced Protection、Expeditionary Mission Command and Networked Electromagnetics、Robots and Autonomous Systems、Seven major equipment for individual soldier/formation bet365 games capabilities and advantage over the enemy、Ability。The Air Force wants to achieve the goal of "multi-domain operations"，The key is to determine the command structure under the multi-domain command and control framework，Enhance situational awareness、Quick decision-making capabilities and cross-domain use capabilities of troops，So the Air Force is relying on the "bet365 games cloud"，Planning “Multi-Domain Command and Control System”。

The second is to accelerate the structural transformation of the Army。“Multi-domain operations” requires the Army to be able to divert bet365 games power from traditional land and air，Expand to the sea、empty、days、Other bet365 games domains such as electricity and cyberspace，Acquire and maintain corresponding bet365 games domain advantages，Support and ensure freedom of movement for joint forces。The Army wants to achieve cross-domain operations、Free switching in the bet365 games space，Strength formation must be sensitive、Lightweight、Characteristics such as leanness and efficiency。For this，The U.S. military will disassemble joint forces to enable rapid deployment、Small-scale troops fighting independently，Multi-line deployment and multi-domain operations，Improve agility and flexibility。The Army must play a role in joint operations，Need to improve the ability of autonomous operations，Pair a helicopter with a drone，Establish a drone platoon for the helicopter reconnaissance battalion，The combination of man and machine improves the reconnaissance range、Time and frequency。At the same time, we must integrate power into the air、Marine and cyber space strike force，To achieve the expansion of capabilities。For this，The Army needs to build a "small organization with large capabilities" force，To adapt to the requirements of "multi-domain operations"。As the US Army Chief of Staff Mina said: The multi-domain bet365 games force is smaller，About 1500 people，Unlike the current army, which has 4,000 troops per brigade，But it can fight in all domains including air, space, sea and land，And support the Air Force、Navy and Marine Corps。

The theory of "multi-domain operations" has developed rapidly in recent years，But there is still a long way to go to achieve deep integration of the various services。Since the US military’s R&D and procurement system is based on military services，Each military service uses systems from different contractors，This undoubtedly increases the complexity of system integration，leading to cross-domain accusations、There is a communication barrier。So although the "multi-domain operations" theory has experienced rapid development，But it will take time to truly develop bet365 games effectiveness。
