A court-martial is one of the most serious legal proceedings a service member can face. The stakes are not just a sentence — they include rank, career, discharge status, and veterans benefits that can affect the rest of a person's life. Character letters, called "matters in mitigation" in military law, are one of the most important tools available to the defense during sentencing.
This guide explains how they work, what military judges look for, and how to write one that genuinely carries weight.
How Character Letters Work in Court-Martial Proceedings
Under Rule for Courts-Martial 1001(c), the defense may present matters in extenuation and mitigation during the sentencing phase of a court-martial. This includes written character statements from anyone who knows the accused — fellow service members, commanding officers, family members, and civilians.
These letters are read by the military judge (in a judge-alone trial) or presented to the panel members (in a jury-style proceeding). They are part of the official record and are considered alongside the service member's official military performance record.
What Makes a Military Character Letter Different
In civilian court, character letters focus on community ties, family, and general good character. In a military court-martial, all of that still applies — but there is an additional dimension that is unique to military proceedings: the service record itself.
A service member who has deployed multiple times, earned commendations, served honorably for years, and contributed to their unit deserves to have that record presented in full. Military judges understand the weight of that service. A letter that speaks to specific deployments, specific acts of courage or leadership, or specific sacrifices made in the line of duty puts the current charge in context in a way that nothing else can.
Who Should Write the Letter
- Commanding officers or senior NCOs — speak directly to military performance, leadership, and character under pressure. Carry the most weight of any writer.
- Fellow service members — speak to day-to-day character, reliability in the field, and the kind of person the accused is when no one is watching
- Family members — describe the human impact of a severe sentence, the accused's role as a parent or spouse, and their life outside the military
- Civilian community members — employers, religious leaders, and neighbors speak to the accused's character in the civilian world, demonstrating that their good character extends beyond the uniform
What to Include in the Letter
Military service and sacrifice
If you are a fellow service member or commander, describe the accused's service record in specific terms. Number of deployments, awards received, leadership roles, specific moments of dedication or sacrifice. This context is essential and only people who served alongside the accused can provide it.
Character under pressure
Military character is tested in ways civilian life rarely replicates. If you have observed the accused under pressure — in the field, during difficult operations, in high-stress environments — describe what you witnessed. These accounts carry extraordinary weight with military judges and panel members who have lived the same experiences.
Acknowledgment of the offense
As with all character letters, briefly acknowledge that you are aware of the charges. Do not minimize them. Then pivot to the full picture of who this person is.
Impact of the sentence
A court-martial sentence can mean discharge, loss of veterans benefits, and the permanent mark of a military conviction. These consequences affect a service member and their family for decades. A family member's letter that describes the human reality of these consequences — especially for children — is one of the most powerful things that can be submitted.

Important: Work With the Defense Counsel
Military defense counsel (JAG attorneys) are experienced in court-martial proceedings and know exactly what the specific judge or panel responds to. Always coordinate with the defense counsel before submitting any letter. They will advise on format, addressee, timing, and which letters are most likely to help.
