The Air Force Office of Special Investigations (AFOSI) was established on August 1, 1948, as a separate agency within the United States Air Force. Its mission is to provide independent criminal investigations and counterintelligence services to protect Air Force personnel and resources. Over the decades, AFOSI has played a crucial role in uncovering espionage, combating terrorism, and investigating major crimes affecting the Air Force globally. Today, AFOSI operates worldwide, with special agents serving both in garrison and deployed environments, ensuring the integrity and security of Air Force operations.
