Rules of Engagement.
Standing Rules of Engagement for US Forces
Overview •
The Rules. The new SROE, CJCSI 3121.01B (released 13 Jun 2005), updated the 2000 version of the SROE and added a section on the Rules of
Force (RUF) for domestic operations. It provides
guidance on the inherent right of self-defense and the application of force for mission accomplishment. It is designed to provide a common template for development and implementation of ROE for the full range of operations from peace to war. It is applicable worldwide to all echelons of command.
•
Applicability. The SROE applies to all U.S. forces responding to military attacks within the US, to all military operations outside the US (unless superseded by other ROE that have been approved by the President or Secretary of Defense), and to domestic support operations (RUF).
The SROE is a SECRET document and not available for public distribution. Portions of the introductory material are not classified as SECRET and may be available at your unit for training purposes. Contact your unit SJA for up-to-date training materials on ROE.
