Stateside Department of the Air Force
Protective Services Operations were bolstered in April 2020 with the consolidation of
Security Forces personnel under the 1st Field Investigation Squadron, headquartered in Quantico, Virginia.
The integration of personnel from both career fields enhances PSO capabilities at 1st FIS, whose mission is to provide full-spectrum, protective security support to the Department of Defense, Air Force senior leaders and visiting foreign dignitaries.
Historically, Air Force protection teams were comprised largely of OSI agents, with a limited number of security forces personnel who served as protective security drivers. Security forces members now play a larger role and assume more responsibilities within the PSO framework. Except for the lead personal security advisor, duties are now interchangeable between OSI and security forces members on a PSO team.
