What Is the Office of Special Investigations (OSI)?
The Office of Special Investigations (OSI), also known as AFOSI, is the investigative agency of the U.S. Air Force. OSI handles criminal investigations, counterintelligence operations, and background investigations involving airmen, guardians, and other service members. Operating under the Department of the Air Force, OSI agents are highly trained federal law enforcement professionals who enforce the Uniform Code of Military Justice (UCMJ) and work to safeguard national security. OSI also investigates criminal activity and security threats involving personnel in the United States Space Force.
What Triggers an OSI Investigation?
An OSI investigation may begin when a report or tip is received involving:
- Sexual assault
- Domestic violence
- Fraud or financial misconduct
- Misuse of government property
- Behavior affecting a security clearance
- Counterintelligence threats
OSI agents may also receive referrals from the chain of command, JAG, CID, NCIS, or other military law enforcement agencies.
How Long Do OSI Investigations Usually Last?
The duration of an OSI investigation depends on the complexity and seriousness of the case. On average, investigations take between 3 to 6 months. However, more complex cases, especially those involving multiple parties or digital forensics, can extend beyond a year. Key factors influencing the timeline include:
- Number of witnesses and interviews required
- Volume of physical and digital evidence
- Whether the subject cooperates with investigators
- Coordination with external law enforcement or military entities
What Happens During an OSI Investigation?
Once initiated, OSI special agents will:
- Conduct interviews with the subject, witnesses, and others
- Collect and analyze digital and physical evidence
- Coordinate with federal or military law enforcement, such as CID or NCIS
- Possibly use surveillance or undercover tactics in serious or sensitive cases
Airmen should take an OSI investigation seriously and contact legal counsel immediately when approached by an OSI agent.
How Does an OSI Investigation Impact Your Military Career?
Being under investigation can have a lasting impact on military service. Even without formal charges, an open OSI investigation may lead to:
- Delays in promotion or PCS orders
- Suspension or revocation of security clearance
- Entry-level separation or administrative discharge
- Potential referral for non-judicial punishment or court-martial
The stakes are high, especially for active duty airmen and those in roles requiring background investigation clearance.
What Rights Do You Have During an OSI Investigation?
Airmen and Guardians under investigation have the following rights:
- The right to remain silent
- The right to legal counsel, including JAG or civilian defense counsel
- Protection against unlawful search and seizure
Do not speak to OSI agents without first securing legal advice. Anything said can be used as evidence and may impact the outcome of the investigation.
What Should You Do If You’re Being Investigated by OSI?
If you’re under investigation, take these steps:
- Do not engage in conversations with OSI agents without your defense attorney present
- Avoid discussing the case with colleagues or on social media
- Contact a military law office for legal support
- Document any communication related to the investigation
Even if this is your first time being investigated, it’s critical to act quickly.
