Atlantic Resolve is a response to Russia’s actions in Ukraine, mainly the war in Donbass, and is funded under the European Reassurance Initiative. The US took several immediate steps to demonstrate solidarity with NATO, such as augmenting the air, ground and naval presence in the region, and enhancing previously scheduled exercises. The US is taking measures to improve NATO military plans and defence capabilities, and remains committed to maintaining a persistent presence in Central and Eastern Europe. This second Guideline in Action looks at the US Air Force’s recent deployments in support of Atlantic Resolve, US Army aviation assets, and multinational training exercises, as well as the transport and logistics efforts behind the maintenance of the front line squadrons.
