Operation Freedom's Sentinel in the context of "U.S. Central Command"

Operation Enduring Freedom (OEF) was the official name used by the U.S. government for both the first stage (2001–2014) of the war in Afghanistan (2001–2021) and related military operations during broader-scale global war on terrorism. On 7 October 2001, in response to the September 11 attacks, President George W. Bush announced that airstrikes against al-Qaeda and the Taliban had begun in Afghanistan. Beyond the military actions in Afghanistan, U.S military command structures operating under the Operation Enduring Freedom banner were also affiliated with several counterterrorism missions in other countries, such as OEF-Philippines and OEF-Trans Sahara.

After 13 years, on 28 December 2014, President Barack Obama announced the end of Operation Enduring Freedom in Afghanistan. Subsequent operations in Afghanistan by the United States' military forces, both non-combat and combat, occurred under the name Operation Freedom's Sentinel.
