U.S. European Command’s mission is to maintain Ready Forces to conduct a full range of operations. Forces are assigned to, trained and equipped by service-specific headquarters or joint and multinational trainers when participating in joint operations or joint exercises.

U.S. Army Europe (USAREUR), U.S. Marine Forces Europe (MARFOREUR), U.S. Naval Forces Europe (NAVEUR), U.S. Air Forces in Europe (USAFE), and Special Operations Command Europe (SOCEUR) provide the forces for all military-to-military engagements with partner nations, provide a deterrence function in the region, and serve as deployable units for contingency operations.
