Department-Level Exercise (DLE) Series

Through this series, the Department of the Air Force is preparing to be a stronger, more lethal deterrent force, to provide an advantage against competitors and adversaries across all domains, and to ensure regional stability in the Indo-Pacific and beyond.

The DLE series will incorporate multiple command exercises into one overall threat deterrence scenario, including Resolute Force Pacific (REFORPAC), Resolute Space, Mobility Guardian, Emerald Warrior and Bamboo Eagle 25-3.

It will also integrate multiple allies and partners in specific component exercises with shared interests. Partner integration is critical to U.S. efforts to ensure regional and global peace and stability and provides a decisive advantage against complex threats.
