Ordering the Selected Reserve and Certain Members of the Individual Ready Reserve of the Armed Forces to Active Duty

The order directs the Secretary of Defense, and the Secretary of Homeland Security for Coast Guard forces not operating under the Navy, to call reserve component service members to active duty to support Operation Atlantic Resolve within the U.S. European Command's area of responsibility. It authorizes activation of units of the Selected Reserve and individual members of the Individual Ready Reserve mobilization category who are designated as essential — up to 3,000 total members at any one time, with no more than 450 drawn from the Individual Ready Reserve. Both secretaries are also authorized to terminate the service of those called up once no longer needed.

The order does not create any legal right or benefit enforceable by any party against the United States, its agencies, officers, or employees.

Units and individual members of the Selected Reserve and Individual Ready Reserve mobilization category across all military branches, as well as Coast Guard reservists, who may be ordered to active duty for Operation Atlantic Resolve in and around the European Command area of responsibility.

Reserve service members designated as essential — up to 3,000 at a time — can be involuntarily called to active duty, potentially disrupting their civilian careers and personal lives. The call-up supplements the existing active force posture in Europe without requiring a broader mobilization.

The two secretaries exercise activation authority independently within their respective jurisdictions, subject to the caps set in the order. No additional trigger or congressional notification process is specified in the order text itself. The secretaries also hold termination authority, meaning the activation lifecycle — call-up through release — is managed within the executive branch. The 3,000-member ceiling is a rolling cap on concurrent activations, not a lifetime total.
