The key differences between Military Police (MPs) authority over military personnel versus civilians center on jurisdiction, legal basis, and scope of enforcement:
1. Authority over Military Personnel:
- MPs have broad authority to enforce military law, orders, and regulations over military personnel, derived primarily from the President as Commander in Chief and codified in the Uniform Code of Military Justice (UCMJ).
- This authority extends to active duty military members, some retired personnel, and others subject to the UCMJ, regardless of location (on or off military installations).
- MPs can apprehend, investigate, and discipline military personnel, including confinement in military correctional facilities (brig).
- National Guard and Reserve MPs generally exercise authority only when under military orders and subject to the UCMJ themselves.
2. Authority over Civilians:
- MPs have limited authority over civilians. Their jurisdiction primarily covers military installations and property, but they may intervene if a crime is witnessed in progress in civilian areas.
- The Posse Comitatus Act restricts federal military personnel, including MPs, from participating in civilian law enforcement except under specific legal exceptions such as martial law or extreme emergencies.
- Even on military bases, MPs’ authority over civilians is constrained; off base, MPs generally have no law enforcement authority over civilians.
- The Coast Guard is an exception, having statutory authority to enforce laws on civilians.
- National Guard MPs may have some civilian law enforcement roles if acting under state authority and official orders.
Summary Table:
| Aspect | Military Personnel | Civilians |
|---|---|---|
| Legal Basis | UCMJ, Presidential authority | Limited; Posse Comitatus Act restrictions |
| Jurisdiction | On and off military installations | Primarily on military property; limited off base |
| Enforcement Powers | Arrest, discipline, confinement | Crime intervention if witnessed; otherwise limited |
| Exceptions | N/A | Martial law, extreme emergencies, Coast Guard authority, National Guard under state orders |
In essence, MPs have comprehensive authority over military personnel under military law, while their authority over civilians is significantly limited by federal law and jurisdictional boundaries.

Your Legal Rights
If You Are Military Personnel: MPs have broad authority under the Uniform Code of Military Justice (UCMJ) to enforce laws and discipline. You have rights under military law, including the right to legal counsel, the right to remain silent, and protections against unlawful punishment.
If You Are a Civilian: MPs have limited authority, mostly confined to military property. The Posse Comitatus Act restricts military involvement in civilian law enforcement except in rare cases (e.g., martial law). You have constitutional rights against unlawful search, seizure, and detention.
General: You have the right to be treated with respect, to understand the reason for any detention or questioning, and to seek legal counsel.
Where to Get Help
- Military Personnel: Contact your base legal office (JAG), your chain of command, or the Inspector General's office for complaints.
- Civilians: Reach out to civilian legal aid organizations, local public defenders, or private attorneys experienced in military or constitutional law.
- Federal Agencies: For complaints about military police misconduct, you can contact the Department of Defense Inspector General or the Civilian Complaint Review Board if available.
- Emergency Help: If you feel threatened or unsafe during an MP interaction, call 911 or local law enforcement immediately.
