ROE for space operations would have to address what defensive and offensive acts are permitted under the jus ad bellum and the jus in bello. Because they can address geographic or physical constraints on the area of operations, they could also reflect space traffic management concerns, thereby reducing the threat of crisis escalation because of proximity concerns. While "targeting directives" are the military orders and doctrinal tool used to review specific targets for potential deliberate and legal strike or engagement, and to assure that collateral damage is properly considered, ROE also address these concerns by providing authorisations for or limitations on specific targets and particular weapon use.
