Operation Atlantic Resolve, though not a "named" operation, is ongoing efforts in response to Russia's actions in Ukraine; mainly the War in Donbas. It is funded under the European Deterrence Initiative. In the wake of Russia's 2014 intervention in Ukraine, the U.S. took several immediate steps to enhance the deterrence posture along the eastern flank of the North Atlantic Treaty Organization (NATO), including augmenting the air, ground and naval presence in the region, and enhancing previously scheduled exercises. The U.S. is taking measures to enhance NATO military plans and defense capabilities and remains committed to maintaining a persistent presence in Central Europe and Eastern Europe. Atlantic Resolve rotations are overseen by a regionally aligned headquarters there.
