No, a commander’s personal endorsement or recommendation for a specific punishment is generally not admissible as evidence during the sentencing phase of a contested court-martial. The determination of an appropriate sentence is the exclusive function of the court-martial panel members (or the military judge in a bench trial). They are required to make their decision based on the evidence presented in court and the specific legal instructions they receive from the judge.
Allowing a commander to introduce their own opinion on what the sentence should be would be a form of Unlawful Command Influence (UCI). It would improperly invade the province of the court members, who must exercise their own independent judgment. The commander’s role is to decide whether to refer the case to trial; once that decision is made, their ability to influence the outcome is strictly limited to prevent the appearance of a commander-dominated justice system.
A military defense attorney would immediately object if the prosecutor attempted to introduce a commander’s recommendation for punishment. The military judge would be required to sustain this objection. The prosecutor can present evidence about the impact of the offense on the unit, but they cannot introduce testimony or documents that tell the panel members what sentence the commander wants them to adjudge. This rule protects the independence and integrity of the court-martial’s sentencing function.
