OSI (Air Force)


Office of Special Investigations

General Information:

The Office of Special Investigations (OSI) was established on August 1, 1948, as the major investigative service for the U.S. Air Force.  With approximately 2,029 active-duty, reserve and civilian special agents, OSI is located at military facilities throughout the U.S. and the world.

In October 1947, in the wake of a national procurement fraud scandal involving a retired general officer, then Secretary of the Air Force (W. Stuart Symington) directed Frank Wilson (retired director of the U.S. Secret Service) and later Joseph Carroll (special assistant to FBI Director J. Edgar Hoover) to develop an independent investigative service.  OSI subsequently became operational as the lead federal law enforcement agency within the Air Force.  To learn more about OSI organizational history, please see the fact book:

OSI has very unique mission capabilities depending on the operating environment.  Within the U.S., OSI conducts felony level criminal investigations related to Air Force personnel (i.e., sexual assaults, homicide, robbery).  These investigations are supported by computer crime specialists, polygraph examiners, and forensic experts (all special agents). OSI also conducts counterintelligence and counterespionage operations within the U.S. to detect and deter foreign intelligence services.  OSI special agents routinely deploy to war zones and conduct force protection human source operations to gather tactical and strategic level intelligence.  

More information can be found within the OSI Brochure.    

The Air Force OSI Recruiting Video also provides great insight into the agency.

Hiring Process (Civilian):

You do NOT need to join the military in order to become a civilian special agent.  The hiring process is similar to other agencies and will take approximately one year.  Applicants must wait for a vacancy announcement and are evaluated as follows:

1.  Online Application & Evaluation

2.  Interview

3.  Medical Examination

4.  Drug Test

5.  Background Investigation

The best candidates are selected to attend the academy.  


All new OSI special agents must complete the 12-week basic Criminal Investigator Training Program (CITP) and the 8-week OSI specific course at the Federal Law Enforcement Training Center.  See the link below for additional information regarding training:
