OEF stands for Operation Enduring Freedom, a military operation conducted by the United States in Afghanistan from 2001 to 2014. Some synonyms for this term include: War in Afghanistan, Afghan War, War on Terror, Operation Freedom's Sentinel, and Operation Resolute Support. These terms are often used interchangeably to refer to the military operations and efforts to combat terrorism in Afghanistan. Each term reflects a different perspective or stage of the operations, but all agree on the fundamental goal of combating terrorism and promoting peace and stability in the region. Regardless of the term used, we honor the sacrifices of the brave men and women who served in the OEF and support continued efforts to achieve lasting peace in Afghanistan and the surrounding region.
