This question goes to the heart of how military law treats criminal attempt. A service member may worry that an attempt charge collapses if completing the crime was never actually possible, for example because the target did not exist, the contraband was fake, or circumstances made success unattainable. Under the Uniform Code of Military Justice, that worry is usually misplaced. The short answer is yes: an accused can be convicted of attempt even when the opportunity to complete the offense was never present.
What Article 80 actually requires
Attempt is charged under Article 80 of the UCMJ. The government must prove four things. First, that the accused did a certain overt act. Second, that the act was done with the specific intent to commit a particular offense under the code. Third, that the act amounted to more than mere preparation. Fourth, that the act apparently tended to effect the commission of the intended offense.
Notice what is missing from that list. There is no element requiring that success was actually possible. The offense punishes a culpable state of mind joined to conduct that moves beyond planning. The law treats a person who tries to commit a crime and fails as dangerous and blameworthy, regardless of whether an outside circumstance, unknown to the accused, doomed the effort from the start.
Factual impossibility is not a defense
The reason a missing opportunity does not defeat the charge is the doctrine of impossibility. Military courts distinguish between factual impossibility and legal impossibility, and they treat the two very differently.
Factual impossibility means the accused intended to commit a real crime but could not complete it because of a fact unknown to the accused. The classic examples include trying to pick an empty pocket, firing at a bed believing a person is asleep in it, or attempting to buy what the accused believes are illegal drugs when the substance is harmless powder. In each case the accused had every intention of committing the offense and took concrete steps to do so. Military law holds that factual impossibility is not a defense to attempt. The accused is judged on the facts as the accused believed them to be, not on the hidden reality that made completion impossible.
The Court of Appeals for the Armed Forces confirmed this principle in United States v. Roeseler, 55 M.J. 286 (C.A.A.F. 2001). There the court affirmed a conviction for attempted conspiracy to murder persons who did not exist, holding that the impossibility of the underlying offense was not a defense. What mattered was the accused’s own belief and intent, coupled with conduct that crossed the line beyond preparation.
Legal impossibility is different
Legal impossibility is a narrower idea, and it can be a defense. Legal impossibility exists when what the accused set out to do would not be a crime even if every step succeeded exactly as planned. If the completed act is simply not an offense under the code, there is no crime to attempt. A person who believes a lawful act is unlawful and tries to do it has not attempted any UCMJ offense, because there is no offense in the first place. This defense rarely arises, because most accused intend conduct that the law actually prohibits.
The practical line is this. If the only reason the crime could not be completed is a fact the accused did not know, that is factual impossibility and it does not help the defense. If the conduct the accused aimed at is not criminal at all, that is legal impossibility and there is nothing to convict.
Why the opportunity to complete is not the test
Because attempt focuses on intent and the overt act, the real prosecutorial questions are whether the accused genuinely intended the offense and whether the conduct went beyond mere preparation. The absence of a real opportunity to finish is generally irrelevant to both. A service member who travels to a meeting place to consummate a drug deal, who hands money to an undercover agent, or who takes a substantial step toward a sexual offense against a person who turns out to be a law enforcement decoy has committed the overt act with the required intent. The fact that no completion was ever possible, because the buyer was an agent or the victim was fictitious, does not undo the attempt.
Where the defense should focus instead
Recognizing that impossibility usually will not carry the day, an effective defense under Article 80 looks elsewhere. The strongest contests are typically over the two elements the government must still prove. Counsel can challenge specific intent, arguing that the accused never formed a settled purpose to commit the particular offense. Counsel can also challenge whether the conduct truly exceeded mere preparation, since acts that are merely preliminary, equivocal, or readily abandoned may fall short of the substantial step the law demands. Entrapment may also be available where government agents induced an otherwise unwilling person to act.
Bottom line
Military law does not let an accused escape an attempt conviction simply because completing the crime was never in the cards. Factual impossibility, including the absence of any real opportunity to finish, is not a defense under Article 80. The conviction turns on the accused’s intent and on conduct that moved beyond preparation toward the intended offense. Only genuine legal impossibility, where the planned act is not a crime at all, removes the foundation for an attempt charge. For anyone facing an Article 80 specification, the defense that has teeth is not impossibility but a careful attack on intent and on whether the alleged act ever rose above mere preparation.
