FORT EUSTIS, Va. —

What is it?

Multi-Domain Operations (MDO) describes how the U.S. Army, as part of the joint force, can counter and defeat a near-peer adversary capable of contesting the U.S. in all domains, in both competition and armed conflict. The concept describes how U.S. ground forces, as part of the joint and multinational team, deters adversaries and defeats highly capable near-peer enemies in the 2025-2050 timeframe.

MDO provides commanders numerous options for executing simultaneous and sequential operations using surprise and the rapid and continuous integration of capabilities across all domains to present multiple dilemmas to an adversary in order to gain physical and psychological advantages and influence and control over the operational environment.

What has the Army done/is doing?

MDO is an evolution and further refinement of the Multi-Domain Battle (MDB) concept published in 2017. It reflects more than two years of experiments, wargames and table-top exercises with Joint Force and multinational partners.

The Army will publish an update to the MDB concept called The U.S. Army in Multi-Domain Operations, 2028 in November 2018. It expands on the ideas of MDB, and describes how the Army contributes to the joint force's principal task outlined in the 2018 National Defense Strategy: how to deter and defeat near-peer strategic competitors in both competition and armed conflict.

What continued efforts does the Army have planned?

The MDO 1.5 concept sets the conditions for further experimentation, war-gaming, and assessment. Army Futures Command will take over responsibility for the development of MDO 2.0. The concept will continue to be revised regularly to account for additional learning, new technologies and updates to the operating environment.

Events such as Unified Challenge and Joint Warfighting Assessment 18, exercises with the Multi-Domain Task Force in the Pacific, and continued work with the joint and multinational partners will contribute to further refining of the concept. MDO 1.5 also sets the conditions for Army modernization, and will provide the primary conceptual foundation for the upcoming Army Modernization Strategy 1.5.

Why is this important to the Army?

The joint force must rapidly and continuously converge capabilities across all domains to win in competition and armed conflict. America's near-peer competitors have invested in strategies and capabilities to create stand-off and separate U.S. alliances in competition, and the joint force in armed conflict.

Countering these threats requires modernizing the Army across doctrine, organizations, training, and materiel to enable the rapid defeat of future adversaries. The MDO sets the foundation for this modernization by establishing how the Army will fight and what it will need to win.
