EBO is not just an emerging concept—it was the basis of the Desert Storm air campaign plan. However, over the years since, multiple views have emerged on what it meant and how it could be implemented. Most notably, military scientists at the Air Force Research Lab, the Army Research Lab and DARPA engaged in research to develop automated tools to annotate options and recommend courses of action. This is hard science and tools are slow to be implemented. For air forces, it supported the ability for a single aircraft to attack multiple targets, unlike tactics of previous wars, which used multiple aircraft to attack single targets, usually to create destruction without thought of later re-use by allied forces or friendly civilians.
