Exercise Resolute Castle is a U.S. Army Europe and Africa led, multinational, joint exercise which marries U.S. Army Reserve and National Guard, as well as allied and partner nation engineering unit training opportunities with the completion of real world construction projects that enhance training capabilities in various areas of Europe's eastern member-states. Resolute Castle is designed to reinforce regional partnerships and promote interoperability with host nation forces by providing improvements to existing infrastructure.

Resolute Castle 2023 is taking place in Drawsko Pomorskie Training Area, Poland. It increases partner capacity and strengthens capabilities across NATO's eastern member states through real world engineer-related training and the construction of enduring facilities, which enhances NATO's ability to project combat power within Europe.
