Multi-Domain Operations

Multi-Domain Operations (MDO) is the United States Army's and NATO's transformational concept of operations. It was created to reflect the 2018 National Defense Strategy, which shifted the previous focus of U.S. national security from countering violent extremists worldwide to confronting revisionist powers—primarily Russia and China. MDO's should not be confused with joint operations which promote coordination with other armed services, while MDOs go beyond that to include military and non-military assets. The concept goes by several different names including Multi-Domain Integration (MDI) (United Kingdom), Multi-Domain Maneuver (Israel), Multi-Domain Deterrence (Taiwan) and Multidimensionalität or Multidimensionality (Germany).

"Multi-Domain Operations are the combined arms employment of joint and Army capabilities to create and exploit relative advantages that achieve objectives, defeat enemy forces, and consolidate gains on behalf of joint force commanders. Employing Army and joint capabilities makes use of all available combat power from each domain to accomplish missions at least cost. Multi-Domain Operations are the Army’s contribution to joint campaigns, spanning the competition continuum," said the Army's Field Manual Operations of October 1, 2022.
