Generally no. Performance data from weapons qualification records, such as marksmanship scores or range proficiency ratings, is not admissible as character evidence in an assault trial because it does not speak to a pertinent character trait and is not a permitted method of proving character. The Military Rules of Evidence allow only specific kinds of character evidence, proved in specific ways, and skill with a weapon is neither a relevant trait for an assault charge nor something that may be shown through performance records. There are narrow situations where such records could be relevant for a different, non-character purpose, but using them to suggest the accused is or is not the type of person who would commit assault will not pass muster. This article explains why.
Character evidence rules in an assault case
In an assault prosecution, the character traits that matter are limited. Under Military Rule of Evidence 404(a), character evidence is generally inadmissible to prove that a person acted in conformity with that character. The accused may, however, offer evidence of a pertinent trait. For a violent offense such as assault, the recognized pertinent trait is peacefulness. An accused may present evidence that he or she is a peaceful person to make it less likely that the accused committed the violent act charged. Once the accused does so, the government may rebut with evidence of the same trait.
The key word is pertinent. A trait is pertinent only if it bears a logical relationship to the offense. Marksmanship skill, range scores, and weapons qualification ratings measure technical proficiency, not disposition toward violence or peacefulness. Just as military courts have held that being a good duty performer or a good service member is not pertinent to whether a person committed a particular offense, proficiency on a weapons range is not a character trait that makes assault more or less likely. A high or low qualification score says nothing about whether a person tends to resolve disputes peacefully.
How character must be proved: reputation and opinion
Even if a party could identify a pertinent trait, Military Rule of Evidence 405 limits the method of proof to reputation and opinion testimony in the ordinary case. Performance data from qualification records is neither. It is documentary evidence of specific instances of measured performance. Specific instances may be used substantively only when a character trait is an essential element of a charge, claim, or defense, which is not the situation in a typical assault prosecution.
So even setting aside the relevance problem, the form of the evidence is wrong. A party cannot prove a character trait by introducing a stack of range scorecards. The rules contemplate a witness who can speak to reputation or give an opinion, not a printout of qualification metrics offered to imply something about the accused’s disposition.
The danger of a forbidden inference
Trying to use weapons qualification data as character proof invites exactly the propensity reasoning the rules forbid. Suggesting that a highly qualified shooter is dangerous, or conversely that a poor shooter is harmless, asks the panel to infer conduct from a trait that has no logical bearing on whether an assault occurred. That is unfair prejudice and confusion of the issues, and a military judge would exclude it under Military Rule of Evidence 403 even if some thread of relevance were claimed.
The same logic cuts against the defense. An accused cannot offer a sterling marksmanship record to argue good character generally, because that record is not pertinent to peacefulness and is not a permitted method of proof. Good performance in one military domain does not translate into a character defense against a violent charge.
When qualification records might be relevant for another purpose
Evidence can be admissible for a non-character purpose even when it would be barred as character proof. If the facts of a weapons qualification event are directly relevant to the assault charge itself, the records might come in for that reason. For instance, if the alleged assault occurred at the range, qualification records or range documentation could establish who was present, the timeline, the equipment issued, or the physical setting. In that scenario the records are offered as factual evidence about the event, not as proof of the accused’s character.
Likewise, under Military Rule of Evidence 404(b), other acts can be admissible to show knowledge, identity, or absence of mistake, but only if the underlying conduct meets the three-part admissibility test and survives MRE 403 balancing. A routine qualification score would rarely satisfy that standard, because it does not tend to prove any of those non-character facts in an ordinary assault case. The point is that any admissibility would rest on a concrete, case-specific connection to the charged conduct, not on a character theory.
Practical guidance for counsel
Counsel on either side should resist the temptation to use service performance metrics as a proxy for character. Trial counsel cannot bolster an assault case by implying the accused’s weapons proficiency makes the accused dangerous. Defense counsel cannot blunt an assault charge by showcasing range scores as evidence of a good character. If a party believes qualification records are genuinely relevant to a disputed fact about the incident, the party should articulate that specific, non-character purpose and be prepared to defend it under MRE 403. Absent such a purpose, the records belong out of the character analysis entirely.
Bottom line
Performance data from weapons qualification records cannot be used as character evidence in an assault trial. The only pertinent trait for a violent offense is peacefulness, and marksmanship proficiency is not that trait. Military Rule of Evidence 405 also forbids proving character through specific-instance performance records in the ordinary case, and Military Rule of Evidence 403 would exclude the evidence as unfairly prejudicial and confusing. Qualification records might enter a case only for a genuine non-character reason tied to the facts of the incident, analyzed where appropriate under MRE 404(b). Used as a character shortcut, by either side, they do not belong in the courtroom.
