USMC PAC Order and MCO 5354.1F: Understanding Prohibited Activities and Conduct.
A USMC PAC order (MCO 5354.1F, Prohibited Activities and Conduct) is a Marine Corps directive that restricts a Marine's activities, associations, and behavior. It is not a punishment in itself. It is a command tool that often comes before NJP, administrative separation, or both. Marines who receive PAC orders at Camp Lejeune, MCAS Cherry Point, New River, and other installations need to know what is restricted, what a violation triggers, and when to call an attorney.

Overview
A PAC order is a command-directed restriction on a Marine's activities and behavior under MCO 5354.1F (Prohibited Activities and Conduct). If you just received one, the first thing to understand is that the PAC order itself is not a punishment. It is a precautionary measure your command uses while an investigation or administrative action is pending. But it frequently leads to NJP, administrative separation proceedings, or a court-martial referral. What happens next depends partly on how you handle the PAC order period.
MCO 5354.1F is the Marine Corps Order that defines prohibited activities and conduct for all Marines. The order covers everything from drug use and domestic violence to unauthorized absences and conduct that brings discredit to the service. When a Marine's behavior triggers a concern under MCO 5354.1F, the command can issue a PAC order restricting the Marine's movement, access, associations, and off-duty activities while the matter is investigated or adjudicated.
PAC orders are common at Camp Lejeune, MCAS Cherry Point, MCAS New River, and every other Marine Corps installation. Matthew Thomas, a former Marine Judge Advocate who served as active-duty defense counsel, has represented Marines through PAC-related proceedings throughout his career. He knows how these orders work from the inside because he operated in the same system that issues them.
The restrictions in a PAC order vary by case. Some PAC orders restrict a Marine to the barracks or base during non-duty hours. Others prohibit contact with specific individuals. Some require the Marine to check in with the duty NCO at designated times. The specific restrictions depend on the underlying misconduct allegation and the commander's assessment of risk. Violating any restriction in the PAC order creates an additional offense, separate from whatever triggered the original order.
Here is the part most Marines miss: a PAC order creates a documented record that follows the case through every subsequent proceeding. If the case goes to NJP, the administrative judge or commanding officer will see the PAC order and whether you complied with it. If the case escalates to an administrative separation board, compliance or non-compliance with the PAC order becomes evidence of character and rehabilitation potential. Every day under a PAC order is a day you are building a record, for better or worse.

A PAC order is not a punishment. It is a record being built. How you handle it shapes everything that comes after.Matthew Thomas, Esq. — USMC PAC Order
What You Need to Know
Read this before you do anything.
01
What is the USMC PAC order?
A PAC order (Prohibited Activities and Conduct order) under MCO 5354.1F is a command-directed restriction placed on a Marine whose behavior has triggered a concern under the Marine Corps prohibited conduct framework. The order restricts the Marine's activities, movement, associations, and in some cases liberty, while the underlying matter is investigated or adjudicated. It is a precautionary measure, not a disciplinary action. But the Marine's compliance or non-compliance during the PAC period becomes part of the case record.
02
What is MCO 5354.1F?
MCO 5354.1F is the Marine Corps Order titled "Prohibited Activities and Conduct." It defines the categories of behavior that are prohibited for Marines, including drug use (also governed by UCMJ Article 112a), domestic violence, extremist activity, gambling, fraternization, hazing, and other conduct that discredits the Marine Corps. The PAC order framework within MCO 5354.1F gives commanders the authority to restrict a Marine's activities when misconduct is suspected or confirmed. The order was most recently revised to consolidate previous iterations including MCO 5354.1E.
03
What does a PAC order restrict?
Restrictions vary by case and commander discretion. Common restrictions include: confinement to barracks or base during non-duty hours, prohibition on contact with specific individuals (common in domestic violence or fraternization cases), required check-ins with the duty NCO at designated intervals, prohibition on consuming alcohol, restriction from specific locations on or off base, and surrender of government-issued identification cards or weapons. The PAC order document itself will list the specific restrictions. Read it carefully. Every restriction is enforceable, and a violation of any one of them is a separate offense under the UCMJ.
04
How does the USMC PAC complaint process work?
A PAC complaint can be initiated by anyone in the chain of command, a military law enforcement report, or a civilian police report forwarded to the installation provost marshal. Once the complaint reaches the commanding officer, the CO evaluates whether PAC restrictions are warranted. The CO then issues a PAC order outlining specific restrictions. An investigation or inquiry may run in parallel. Based on the outcome, the command decides whether to pursue NJP under Article 15 of the UCMJ, refer the case to a court-martial, initiate administrative separation proceedings, or close the matter with no further action.
05
What is EPD in the USMC?
EPD stands for Extra Punitive Duty. It is a form of punishment that can be imposed at NJP (non-judicial punishment under Article 15 of the UCMJ). EPD requires the Marine to perform additional duties during designated hours for a specified number of days. EPD is distinct from a PAC order. A PAC order is a pre-adjudication restriction. EPD is a post-adjudication punishment. However, Marines frequently receive a PAC order first, then face NJP where EPD is one of the possible outcomes. The two are related in practice even though they serve different legal purposes.
06
What are the consequences of a PAC violation?
Violating a PAC order is a separate offense. It can be charged under Article 92 of the UCMJ (failure to obey a lawful order) in addition to whatever misconduct triggered the original PAC order. A PAC violation also signals to the command that the Marine is not taking the process seriously. That perception can escalate the command's response: a case that might have resolved at NJP can get referred to a court-martial. A case heading for NJP can shift to an administrative separation with an other-than-honorable characterization. Compliance with the PAC order is the single most controllable factor during this period.
07
When do you need legal representation for a PAC matter?
The short answer: as soon as the PAC order is issued. The PAC order itself means the command is taking the underlying allegation seriously enough to restrict your liberty. What follows is typically an investigation, then a decision on whether to pursue NJP, court-martial, or administrative separation. Having an attorney in place from the PAC stage means the defense is building its case from the earliest possible point. Matthew Thomas is a former Marine JAG who served as active-duty defense counsel. He handles PAC-related matters for Marines at Camp Lejeune, Cherry Point, New River, and installations nationwide.
How It Works
The process, step by step.
Complaint or report is filed
A PAC complaint can originate from the chain of command, military law enforcement (PMO/CID), or a civilian police report forwarded to the installation. The complaint identifies the Marine and the suspected prohibited conduct under MCO 5354.1F.
Commanding officer reviews and issues PAC order
The commanding officer evaluates the complaint and determines whether PAC restrictions are warranted. If yes, the CO issues a written PAC order specifying the restrictions. The Marine receives a copy and acknowledges the restrictions in writing.
Investigation or inquiry runs in parallel
While the PAC order is in effect, the command may conduct a preliminary inquiry (PI), a command investigation, or refer the matter to NCIS or CID depending on the severity of the allegation. The investigation findings inform what action the command takes next.
Command decides on disposition
Based on the investigation, the commanding officer decides the next step: NJP under Article 15 of the UCMJ, referral to a court-martial, initiation of administrative separation proceedings, or no further action. The Marine's compliance with the PAC order during this period is part of the command's calculus.
NJP, court-martial, or administrative separation proceeding
If the command pursues formal action, the Marine faces NJP (where punishments can include reduction in rank, forfeiture of pay, restriction, and EPD), court-martial (where a conviction can result in a federal criminal record and confinement), or an administrative separation board (where the characterization of discharge is at stake).

Section 01
What a PAC Order Is and What It Does
A Protective Action Condition Order (PAC Order) is a written administrative order issued by a commanding officer that restricts a Marine's conduct, movement, and contact. It is not a criminal charge. It is not a formal disciplinary action. It is a temporary administrative measure that a command can issue quickly (often before any investigation is complete) to manage a perceived risk.
PAC Orders typically prohibit specific conduct: contact with a named individual, presence in specific locations (on-base or off-base), possession of weapons, consumption of alcohol, or departure from the local area without command approval. The specific restrictions vary by case and are spelled out in the order itself.
PAC Orders are most commonly issued in cases involving allegations of sexual assault, domestic violence, drug use, or violent conduct. They frequently precede NJP or administrative separation proceedings. Receiving a PAC Order is usually the first indication that formal disciplinary action is being considered.
Section 02
Why You Need an Attorney Before a PAC Order Becomes Something Else
The most dangerous window in any military legal matter is the period between the PAC Order and whatever comes next. During that period, the command is gathering evidence, interviewing witnesses, and deciding how to proceed. Anything a Marine says or does during this window (to the command, to fellow Marines, to the alleged victim) can shape the next proceeding profoundly.
A Marine who receives a PAC Order and then contacts the subject of a no-contact restriction has now committed a separate act of potential misconduct. A Marine who talks to fellow Marines about what happened has introduced potential witnesses. A Marine who consents to an interview with investigators without counsel has waived critical protections.
Getting an attorney in place immediately after receiving a PAC Order allows you to understand exactly what you can and cannot do, what to say and not say, and how to behave during the investigation period in a way that does not add to the problem.
Do Not Contact the Subject of a No-Contact Restriction
Violating a PAC Order restriction, particularly a no-contact restriction, is a separate act of misconduct that can be independently charged under the UCMJ. It also makes the underlying case worse. If you have questions about what the order permits, consult an attorney before acting.
Section 03
What Typically Follows a PAC Order
A PAC Order is almost always a precursor to something else. The most common outcomes: the matter is resolved administratively with no further formal action (relatively rare unless the underlying allegation is determined to be unfounded), the matter proceeds to NJP (Article 15 nonjudicial punishment), or the matter proceeds to formal administrative separation proceedings.
In serious cases involving allegations of violent crime, sexual assault, or significant drug offenses, the matter may proceed to court-martial referral. The PAC Order period is the investigation and charging decision period, the time when the evidence is gathered and the charging decision is made.
The outcome of the PAC Order period matters enormously. How you conduct yourself, whether you cooperate or invoke your rights, and whether you retain counsel before the investigation concludes can all shape what happens next.
Section 04
PAC Orders and Security Clearances
A PAC Order can trigger a security clearance review. If the underlying conduct that led to the PAC Order involves conduct covered by SEAD-4 adjudicative guidelines (drug use, complex drug misconduct, personal conduct, criminal activity) the command may notify the relevant security officer, who may initiate a clearance review or suspension.
Marines who hold clearances and receive PAC Orders should treat both tracks (the UCMJ and administrative track, and the clearance track) as requiring immediate attention. Matthew handles cases that cut across both UCMJ proceedings and security clearance implications, which is common in the Camp Lejeune area where many positions involve classified access.

Common Questions
Frequently Asked Questions
Yes. A PAC Order is a lawful order issued by a commanding officer. Violation of a lawful order can be charged under UCMJ Article 92 (Failure to Obey Order or Regulation), which carries potential for court-martial and substantial punishment. If you believe the order is unlawful or unclear, consult an attorney rather than simply disregarding it.
The procedures for challenging a PAC Order depend on the specific order and the command. In some cases, there are administrative channels for challenging restrictions that are overly broad or not supported by the facts. Matthew can advise on whether a challenge is appropriate and, if so, how to pursue it without making the underlying situation worse.
PAC Orders typically specify their duration or tie to a specific event (such as the completion of an investigation or the conclusion of proceedings). Commands can extend or modify PAC Orders as circumstances change. If a PAC Order has been in place for an extended period without any formal proceeding being initiated, that may be a basis for requesting modification or termination.
Retain counsel immediately. The period between a PAC Order and formal proceedings is the most important window for protecting your rights and position. Do not make statements to investigators without counsel. Do not discuss the matter with fellow Marines. Do not contact any named individual under a no-contact restriction. Call Matthew.
