In military criminal law, helping someone is not a single concept. The law treats assistance very differently depending on when it occurs and what it accomplishes. Helping a person while a crime is being committed can make the helper just as guilty as the person who physically carried out the offense. Helping someone get away from lawful custody, or helping them after a crime is complete, is governed by separate rules with separate elements and separate punishments. Understanding this timeline is the key to seeing why assisting an escape is evaluated so differently from aiding during the commission of a crime under the Uniform Code of Military Justice.
Aiding During the Commission of a Crime: Principal Liability
The starting point is Article 77 of the UCMJ, codified at 10 U.S.C. 877, which defines who is a principal. Under Article 77, a person who commits an offense is a principal, and so is a person who aids, abets, counsels, commands, or procures its commission, or who causes an act to be done that would be punishable if directly performed. The practical effect is that someone who assists in a crime while it is happening is treated as though he committed the crime himself.
Two things are required for this kind of liability. First, the person must do something to assist, encourage, advise, counsel, or command the commission of the offense. Second, the person must share in the criminal purpose. Mere presence at the scene is not enough. A service member who watches an offense unfold, even an obvious one, does not become a principal unless he does something to further it while sharing the intent behind it.
Because the aider during commission is treated as a principal, he is exposed to the same offense and the same maximum punishment as the person who physically performed the act. The assistance is folded into the underlying crime itself. There is no separate, lesser charge for having helped; the helper answers for the full offense.
Assisting an Escape: A Separate Offense After Custody Attaches
Assisting an escape is analyzed under a different framework because it concerns conduct directed at lawful custody rather than at the original criminal act. The UCMJ addresses escape and related conduct in Article 87a, codified at 10 U.S.C. 887a, which covers resisting apprehension, fleeing from apprehension, breaking arrest, and escaping from custody or confinement. A person who frees himself from lawful custody before being released by proper authority commits escape. The mental element matters here: the conduct must be knowing and intentional, so accidental or unintentional departure does not satisfy the offense.
Someone who helps another escape can be liable in more than one way. If the helper actively assists the escape while sharing the escapee’s purpose, principal liability under Article 77 can attach to the escape offense itself, just as it would for any other crime. In addition, the UCMJ separately addresses the unauthorized release of prisoners. Article 96, codified at 10 U.S.C. 896, makes it an offense to release a prisoner without proper authority or to allow a prisoner to escape through design or through neglect. This article reaches guards, escorts, and confinement personnel who have custodial responsibility, and it can also reach others who deliberately participate in an unlawful release or rescue.
The crucial point is that assisting an escape targets a different protected interest. The original crime injures the victim or the good order the offense violated. An escape injures the integrity of lawful custody and the administration of justice. The law therefore evaluates the helper’s conduct against the custodial relationship and the proper authority that controls release, not against the elements of the original underlying offense.
The Role of Timing and the Accessory After the Fact
Timing is the organizing principle. Conduct that occurs during the commission of an offense and furthers it produces principal liability under Article 77. Conduct that occurs after an offense is complete, and that is designed to help the offender avoid apprehension, trial, or punishment, is treated as accessory liability under Article 78, codified at 10 U.S.C. 878. The accessory after the fact is someone who did not participate in the original offense but later assists the offender to escape the consequences, for example by harboring the offender, concealing evidence, or warning the offender of an investigation.
Escape sits at the intersection of these ideas. Helping a person flee lawful custody can look like aiding an escape offense as a principal under Article 87a, like an unauthorized release under Article 96, or like accessory-after-the-fact conduct under Article 78, depending on the helper’s role, the custodial relationship, and exactly when the help was given. By contrast, aiding during the commission of the original crime is squarely principal conduct under Article 77 and carries the full weight of that underlying offense.
Why the Distinction Produces Different Outcomes
Several practical consequences flow from these differences. The aider during commission faces the original offense itself, with its elements and its maximum punishment. The person who assists an escape faces a distinct offense, with its own elements focused on custody and authority, and with its own maximum punishment that is set independently of the original crime. Article 96, for instance, distinguishes between allowing an escape through neglect and allowing one through deliberate design, with the deliberate conduct carrying the heavier penalty, reflecting the law’s judgment that intentional defeat of lawful custody is more culpable than mere carelessness.
These distinctions also shape the proof. To convict the aider during commission, the government focuses on the helper’s contribution to the original crime and his shared criminal intent. To convict for assisting an escape, the government focuses on the existence of lawful custody, the helper’s role in defeating it, and the helper’s knowledge and intent regarding the escape or release.
The Bottom Line
Military law draws a sharp line based on when help is given and what it is aimed at. Aiding during the commission of a crime makes the helper a principal under Article 77, answerable for the underlying offense as though he committed it. Assisting an escape is evaluated under the separate offenses that protect lawful custody, including escape under Article 87a and unauthorized release of a prisoner under Article 96, with accessory-after-the-fact liability under Article 78 available when the help comes after the crime is complete. The difference is not a technicality. It determines which offense is charged, what the government must prove, and how severe the punishment can be. A service member who is accused of helping another, in any of these forms, should consult experienced defense counsel to identify exactly which theory the government is pursuing and how to respond.
