Battle context
Operation Enduring Freedom was launched on 7 October 2001 as the direct U.S. military response to the September 11 attacks. President George W. Bush announced the commencement of airstrikes against al-Qaeda and Taliban targets in Afghanistan, opening what became the first stage of the Afghanistan War and the principal military expression of the broader global war on terrorism. The operation ran through 2014, encompassing a succession of U.S. commanders including Tommy Franks, David Petraeus, and others, while facing Taliban leadership under Mohammad Omar and al-Qaeda figures including Osama bin Laden and Ayman al-Zawahiri. Recorded casualties reached 66,000 on the coalition side and 72,000 for Taliban forces over the course of the conflict. Beyond Afghanistan, the OEF designation served as an umbrella for affiliated counterterrorism missions in other theaters, including OEF-Philippines and OEF-Trans Sahara, making it one of the most geographically expansive operational frameworks in modern U.S. military history.
