The AFOSI Office of Procurement Fraud Investigations, abbreviated as APFI, is a specialized unit within the U.S. Air Force’s Air Force Office of Special Investigations (AFOSI). Its primary role is to detect, investigate, and deter procurement fraud, which involves any illegal or dishonest activity in the process of acquiring goods or services for the U.S. Air Force. This can range from bribery and conflict of interest to false claims and embezzlement. The APFI collaborates with other law enforcement agencies, legal advisors, and auditors to ensure compliance with federal acquisition regulations and maintain the integrity of the procurement process in the U.S. Air Force.
