United States Army: Operation Atlantic Resolve
 
Latest update: October 2019
 
Operation Atlantic Resolve
 
In June 2014 the European Reassurance Initiative (ERI) came into effect after a visit by President Barack Obama to Poland. ERI funds Operation Atlantic Resolve (OAR) which demonstrates the United States commitment to peace, security and stability in Europe by deploying assets (air, land and sea) on a rotational bases. Most of the deployments are focused on the central and eastern European (NATO) countries with the deploying units commanded by US European Command (USEUCOM).

In January / February 2017 the US Army deployed its first brigades - Armored Brigade Combat Team (ABCT) and Combat Aviation Brigade (CAB) to Europe in support of OAR. The ABCT and CAB rotations are nine months. About two months prior to the start of a new rotation the US Army announces the brigades who will deploy.

CAB's are shipped to a port in Europe (main contingents arrived in Belgium, Germany and The Netherlands with some helicopters shipped to Greece or airlifted to Germany). From there they fly to an air base for refuel and checks and then continue to their destinations in southern Germany where the brigades are headquartered. The Blackhawks are forward deployed to the Baltic countries, Poland and Romania.
