Self-Defense in Military Court-Martial Cases
Self-defense is likely the strongest defense in military assault (Article 128 UCMJ) cases — and the most frequently botched. If the facts show you were protecting yourself or someone else, that is not a criminal act. Under military law, properly raised self-defense is a complete defense to assault. The government cannot convict you if it cannot disprove self-defense beyond a reasonable doubt. That is the law. The problem is that too many service members go to trial with defense counsel who fail to properly raise the issue, fail to request the right jury instructions, and fail to build the factual record that self-defense demands. You cannot afford those mistakes.
Philip Cave and Nathan Freeburg have spent a combined 65+ years defending service members facing assault charges — from barracks fights and mutual altercations to domestic violence allegations and overseas incidents. If the facts support self-defense, we know how to present it. If the government is calling your act of self-defense a crime, call us.

Self-Defense Is a Complete Defense — But the Government Will Not Concede It
Under military law, self-defense completely negates an assault charge. It is not a mitigating factor. It is not a reason for leniency at sentencing. If self-defense is properly raised and the government cannot disprove it beyond a reasonable doubt, you must be acquitted. See United States v. Stanley, 71 M.J. 60 (C.A.A.F. 2012); United States v. Yanger, 67 M.J. 56 (C.A.A.F. 2008).
The burden of disproving self-defense belongs entirely to the prosecution once the issue is raised by the evidence. The accused does not have to prove anything. The government must prove beyond a reasonable doubt that the accused was not acting in self-defense. That is a high bar — but only if defense counsel does the job of raising it correctly.
In practice, the Office of Special Trial Counsel (OSTC) and military prosecutors often charge first and ask questions later. Mutual altercations get charged as aggravated assault. Acts of self-defense get characterized as unprovoked attacks. The alleged victim’s own aggression disappears from the narrative. Your job — and ours — is to put it back.
The Two Elements of Self-Defense Under Military Law
The Court of Appeals for the Armed Forces (CAAF) has stated the test for self-defense clearly and consistently. Two elements must both be satisfied:
(1) The accused apprehended, on reasonable grounds, that bodily harm was about to be inflicted on him wrongfully; and
(2) The accused believed that the force he used was necessary to protect against that harm.
United States v. Stanley, 71 M.J. 60 (C.A.A.F. 2012); United States v. Yanger, 67 M.J. 56 (C.A.A.F. 2008).
Both elements have a subjective and objective component. The apprehension of harm must have been actual — the accused must have genuinely believed harm was coming — and it must have been based on reasonable grounds, meaning a reasonable person in the accused’s position would have shared that belief. The belief about the necessity of force is similar: the accused must actually have believed force was necessary, and that belief must be reasonable under the circumstances.
What matters is what the accused reasonably perceived at the time, not what turned out to be objectively true after the fact. If the accused reasonably believed he was about to be struck — even if the other party later claims they were only gesturing or bluffing — the first element can be satisfied. This is where experienced defense counsel earns the outcome: reconstructing the scene as the accused experienced it, not as the government rewrites it.
Proportionality — Force Must Match the Threat
Self-defense does not authorize unlimited force. The force used must be proportional to the threat faced. Stanley, 71 M.J. 60. The law draws a critical line: deadly force cannot be used in response to a non-deadly threat.
But proportionality is assessed from the accused’s reasonable perspective at the time, not with the benefit of hindsight. If the accused reasonably believed a punch could become a deadly beating — based on the disparity in size, the ferocity of the attack, the surroundings, or past history between the parties — force that might seem disproportionate to an outside observer may be entirely justified under the law.
This is where cases are won and lost. A government expert or prosecutor will stand before the jury and argue the accused used too much force. A skilled defense attorney will lay the foundation for why — given everything the accused knew and observed in that moment — the response was reasonable. Physical size differential, prior threats, the location, the number of attackers, the accused’s ability to retreat — all of these feed into the proportionality analysis.
We have successfully argued proportionality in cases involving soldiers, NCOs, and officers across every branch. In one case, an Army E-4 accused of assaulting a female Soldier went to trial. The military judge found him not guilty of all charges. In another, a Soldier at Fort Bragg accused of strangling and assaulting another Soldier had no federal conviction and served no confinement.
The Initial Aggressor Doctrine — and Why It Does Not Always Bar Self-Defense
The most common government argument against self-defense is that the accused started it. If you were the initial aggressor, the argument goes, you cannot claim self-defense. That is partially true — and critically incomplete.
The law is clear: an initial aggressor loses the right to self-defense. United States v. Behenna, 71 M.J. 228 (C.A.A.F. 2012). But that right is not permanently forfeited. An initial aggressor regains the right to self-defense in two circumstances:
- The other party escalated the force beyond what the accused initially used; or
- The accused withdrew from the fight in good faith.
United States v. Stanley, 71 M.J. 60 (C.A.A.F. 2012); United States v. Behenna, 71 M.J. 228 (C.A.A.F. 2012).
This matters enormously in military cases. A service member who throws the first punch but is then pinned to the ground and pummeled has not forfeited self-defense forever. The moment the other party escalated — moved to a weapon, began choking, kicked while the accused was down — self-defense is back on the table.
Government prosecutors understand this doctrine. They will present the case as one continuous attack by the accused and ignore the escalation that happened in the middle. Defense counsel must dissect the timeline, identify the moment of escalation, and make that the centerpiece of the defense. That requires preparation, case investigation, and familiarity with how CAAF has drawn these lines.
Mutual Combat and the Right to Self-Defense
Mutual combat is a scenario the government loves to collapse into a simple assault charge against the service member who caused the most visible injury. Both parties agreed to fight — that makes you equally guilty, goes the theory. It is not that simple.
A mutual combatant does not permanently forfeit self-defense. Under United States v. Lewis, 65 M.J. 85 (C.A.A.F. 2007), a mutual combatant regains the right to self-defense when the other party escalates the conflict beyond the terms of the mutual engagement. The same principle established in the initial aggressor context applies: once the other party raises the stakes in a way the accused did not agree to — pulling out a weapon, continuing after the accused is incapacitated, or escalating to potentially lethal force — self-defense becomes available again.
Lewis also addressed an argument the government frequently makes: that a mutual combatant who could have retreated, but did not, forfeits self-defense. The CAAF rejected that in Lewis. A mutual combatant who is physically incapable of withdrawing — pinned, surrounded, or otherwise unable to disengage safely — is not required to do so. Self-defense remains available.
This doctrine changes the analysis in a barracks fight, a unit altercation, or any case where both parties were willing participants at the outset. The question becomes not who started it, but what happened in the middle — and whether the escalation justified the accused’s response.
No Duty to Retreat in Military Law
Some civilian jurisdictions impose a duty to retreat before using force in self-defense. Military law does not. There is no general duty to retreat under the UCMJ.
The availability of retreat is one factor the factfinder may consider when evaluating whether the accused’s belief about the necessity of force was reasonable. It is not a requirement, and failure to retreat does not forfeit self-defense. But it is a factor — which means government counsel will argue it, and defense counsel must be prepared to address it.
The more important questions are whether the accused was the aggressor and whether the force used was proportional. A service member who had every opportunity to walk away but chose to stand his ground and respond proportionally to a genuine threat has not committed assault. The law recognizes that reasonable people do not always flee, and that retreating is not always safe or possible.
An Army Lieutenant Colonel at Fort McNair was accused by his ex-wife of pushing and grabbing during a domestic dispute. The government brought the case to a full contested trial. After thorough preparation and cross-examination by Nathan Freeburg, he was acquitted on every charge. His retirement was preserved. The alleged victim’s own conduct and the dynamics of the encounter — the context that the government wanted to erase — were front and center at trial.
Defense of Another
The right to use force in self-defense extends to the defense of others. Under military law, a service member may use force to protect a third person from wrongful bodily harm under the same principles that govern self-defense. The accused must reasonably apprehend that bodily harm was about to be wrongfully inflicted on the third person, and must reasonably believe the force used was necessary to prevent it.
Defense of another arises in cases involving intervening in a fight, protecting a fellow Soldier or family member, and responding to attacks on bystanders. The proportionality requirement applies here as well — the force used to protect another must be proportional to the threat facing that person.
This defense is underused and underargued. If you intervened to protect someone else and are now facing assault charges for it, that story needs to be told effectively at trial. We know how to tell it.
The Consent Intersection — When the Victim’s Conduct Matters
Self-defense and consent are distinct defenses, but they can overlap in important ways. Consent is a complete defense to assault consummated by a battery — a victim who consents to touching cannot later claim that touching was offensive. United States v. Mader, 81 M.J. 105 (C.A.A.F. 2021). Consent is generally not a complete defense to aggravated assault. United States v. Atchak, 75 M.J. 193 (C.A.A.F. 2016).
But even when consent is not a full defense, the victim’s consenting conduct is relevant to the accused’s mental state. United States v. Williams, 836 F.3d 1 (D.C. Cir. 2016). In Williams, the D.C. Circuit reversed a murder conviction because the prosecution improperly told the jury it could not consider the victim’s consent when evaluating the defendant’s intent. The court held that while consent may not excuse the conduct, the victim’s voluntary participation directly bears on whether the accused had the required mental state for the offense.
In military assault cases, this means that when an alleged victim agreed to fight, encouraged escalation, or was a willing participant at the outset, that conduct is relevant to whether the accused intended wrongful harm — even if consent does not excuse everything that followed. A skilled defense attorney raises this at the motion stage, fights for proper jury instructions, and uses the victim’s conduct to undercut the government’s theory of intent.
Why Self-Defense Fails — And Why It Doesn’t Have To
Self-defense is raised and lost in the courtroom every day not because the facts were wrong, but because the defense was mishandled. Here is how it happens:
- Defense counsel fails to request a self-defense instruction. If the instruction is not requested, the panel may never be told the law. This is a fundamental error that has reversed convictions on appeal — but you should never be in that position at trial.
- Defense counsel fails to build the factual record. Self-defense requires evidence that the accused reasonably apprehended harm. That means witness testimony, physical evidence, prior incidents between the parties, statements about threats, and any other evidence showing what the accused faced in that moment. If that evidence is not developed before trial and presented at trial, the instruction is theoretical and the defense is hollow.
- Defense counsel concedes the wrong facts. Telling the jury your client “may have overreacted” is not a self-defense argument. It is a concession that destroys the defense. Either the accused was reasonably defending himself, or he was not. The defense must be committed.
- Defense counsel fails to challenge the initial aggressor framing. The government will call your client the aggressor. Defense counsel must investigate whether that framing is accurate, whether escalation occurred after any initial act by the accused, and whether the jury instruction properly accounts for escalation and regaining the right to self-defense.
- Defense counsel fails to use expert witnesses or request proper voir dire. In cases involving questions of reasonable perception, force dynamics, or physical capability to retreat, expert testimony can be essential. Voir dire on self-defense concepts can identify jurors who will hold the accused to an impossible standard.

Frequently Asked Questions: Self-Defense in Military Court-Martial Cases
Q: What are the elements of self-defense under military law?
A: Self-defense under the UCMJ requires two elements: (1) the accused apprehended, on reasonable grounds, that bodily harm was about to be wrongfully inflicted on him, and (2) the accused believed that the force used was necessary to protect against that harm. Both elements have a subjective component — what the accused actually believed — and an objective component — whether that belief was reasonable. See United States v. Stanley, 71 M.J. 60 (C.A.A.F. 2012); United States v. Yanger, 67 M.J. 56 (C.A.A.F. 2008).
Q: Does the government have to prove I was NOT acting in self-defense?
A: Yes. Once self-defense is raised by the evidence, the burden shifts to the government to disprove it beyond a reasonable doubt. You do not have to prove you acted in self-defense. The government must prove you did not. This is a significant burden — but only if defense counsel raises the issue properly and builds a factual record that supports it.
Q: What does proportionality mean in a self-defense case?
A: The force you used must be proportional to the threat you faced. You cannot use deadly force to respond to a non-deadly threat. But proportionality is assessed from your reasonable perspective at the time — not with hindsight. A smaller person responding to a larger attacker, someone facing multiple assailants, or someone who had no way to know the attack would stop — these contextual factors matter. Stanley, 71 M.J. 60. Experienced defense counsel will frame the proportionality question around what you reasonably perceived, not around what looked bad on paper afterward.
Q: What if I started the fight — can I still claim self-defense?
A: It depends on what happened after you initiated the confrontation. An initial aggressor loses the right to self-defense — but regains it if the other party escalated the force or if the accused withdrew from the fight in good faith. United States v. Behenna, 71 M.J. 228 (C.A.A.F. 2012); United States v. Stanley, 71 M.J. 60 (C.A.A.F. 2012). The government will try to freeze the narrative at the moment you struck first and ignore everything that happened after. Defense counsel must break the timeline apart and show when the other party escalated and why your response was justified at that moment.
Q: What about mutual combat — if we both agreed to fight, do I have a self-defense claim?
A: A mutual combatant can regain the right to self-defense when the other party escalates beyond the terms of the mutual engagement. United States v. Lewis, 65 M.J. 85 (C.A.A.F. 2007). If you both agreed to a fistfight and the other person pulled out a weapon, continued after you were incapacitated, or escalated to potentially lethal force, self-defense applies to your response. Lewis also established that a mutual combatant who is physically incapable of withdrawing is not required to do so.
Q: Do I have a duty to retreat before using force in self-defense?
A: No. Military law does not impose a general duty to retreat. Whether retreat was available is one factor the factfinder may consider in evaluating whether your belief that force was necessary was reasonable — but failure to retreat does not forfeit your right to self-defense. This is different from some civilian jurisdictions that impose a duty to retreat before using force. In the military, the key questions are whether you were the aggressor and whether the force you used was proportional.
Q: Can I use force to defend someone else?
A: Yes. Military law recognizes defense of another under the same principles as self-defense. You must have reasonably believed that wrongful bodily harm was about to be inflicted on the other person and that the force you used was necessary to prevent it. Proportionality still applies — the force used must match the threat facing the person you were protecting. This defense is frequently raised in cases involving soldiers who intervened in a fight or responded to an attack on a family member or fellow service member.
Q: How does an experienced defense attorney build a self-defense case?
A: It starts before trial. We investigate the incident thoroughly — reviewing witness statements, identifying inconsistencies in the alleged victim’s account, gathering any evidence of prior threats or altercations, and developing a clear factual narrative of what the accused actually perceived and why. We secure the right jury instructions at trial, including instructions on escalation, proportionality, and the government’s burden to disprove self-defense. We conduct voir dire to identify and challenge panel members who hold the accused to an impossible standard. We cross-examine the alleged victim and government witnesses on the dynamics of the encounter. And we make sure the panel understands that the law requires acquittal if the government has not disproved self-defense beyond a reasonable doubt. Done right, self-defense wins. Done wrong, it disappears.
