1-24. As a part of joint operations, the Army is the dominant fighting force in the land domain. Across the globe, mission-tailored Army units build partnerships, deter adversaries, and overcome challenges to defeat enemies using simultaneous actions integrated in time, space, and purpose. Army forces both depend on and enable joint forces across all domains and the information environment. This mutual interdependence creates powerful synergies and reflects that all operations have multi-domain components. The Army depends on the other Services for strategic and operational mobility, joint fires, and other key enabling capabilities like information collection in the deep area. The Army supports other Services, combatant commands, and unified action partners with ground-based indirect fires and ballistic missile defense, defensive cyberspace operations, electronic protection, communications, intelligence, rotary-wing aircraft, logistics, and engineering.
