Upgrading Discharge for PTSD and MST: Hagel and Carson Memos Explained

For decades, veterans who were discharged due to behavior caused by untreated PTSD or military sexual trauma had no meaningful recourse. Their misconduct was documented; the underlying mental health crisis was not. Two landmark policy directives changed everything. The Hagel Memo (2014) and Carson Memo (2017) require military discharge review boards to give "liberal consideration" to mental health conditions as a mitigating factor — including conditions that were never diagnosed during service. If your discharge was driven by PTSD, MST, depression, TBI, or substance use connected to mental health, you may have grounds for an upgrade that didn't exist ten years ago.

The Problem These Memos Solve

Before 2014, the military's discharge review system evaluated misconduct at face value. A veteran who went AWOL was evaluated on whether they went AWOL — not on why. A veteran discharged for drug or alcohol violations was evaluated on the violation — not on whether the substance use was a veteran self-medicating for undiagnosed combat trauma. A survivor of military sexual assault who exhibited behavioral changes was evaluated on the behavior — not on what caused it.

The consequences were severe and often permanent. Veterans who received Other Than Honorable (OTH) or General discharges for behavior driven by untreated mental health conditions lost access to VA health care, disability compensation, GI Bill benefits, and home loans. The military essentially punished servicemembers twice for conditions the military itself created — or failed to treat.

By 2014, the problem was well-documented. Research showed that veterans with PTSD were disproportionately represented in the population receiving less-than-honorable discharges. Veterans advocacy organizations had built extensive records of servicemembers discharged for behavior that was a direct symptom of service-connected mental health conditions. The Department of Defense was forced to acknowledge the systemic failure and respond.

The Hagel Memo (2014): PTSD and TBI

On September 3, 2014, Secretary of Defense Chuck Hagel issued a memorandum titled "Supplemental Guidance to Military Boards for Correction of Military/Naval Records Considering Discharge Upgrade Requests by Veterans Claiming Post Traumatic Stress Disorder." The memo directed all Discharge Review Boards (DRBs) and Boards for Correction of Military Records (BCMRs/BCNR) to apply new standards when evaluating upgrade requests from veterans with PTSD or TBI.

The core directive of the Hagel Memo:

The memo also addressed the specific challenge of personality disorder discharges — a category that had been widely misused to discharge veterans who were actually experiencing PTSD. Before the Hagel Memo, servicemembers were sometimes given personality disorder characterizations that (a) blocked VA benefits and (b) relieved the military of responsibility for the condition. The memo directed boards to carefully scrutinize personality disorder discharges when PTSD was potentially involved.

Key provisions of the Hagel Memo:

• PTSD or TBI doesn't have to have been diagnosed at the time of discharge — retroactive diagnosis is permitted
• The condition must have "contributed to" the misconduct — this is a lower standard than "caused" or "was the sole cause"
• Boards must give the benefit of the doubt to the veteran when evidence is "in approximate balance"
• Applies to all military branches, all DRBs, and all BCMRs/BCNR
• Applies both to requests for character-of-service upgrades and changes to reason for separation

The Carson Memo (2017): All Mental Health Conditions

On August 25, 2017, acting on behalf of Secretary of Defense James Mattis, the Army Secretariat issued a memorandum expanding the liberal consideration standard to cover all mental health conditions — not just PTSD and TBI. This directive is commonly referred to as the "Carson Memo" in the veterans legal community, though it was formally issued by Secretary Fanning's office in the Army Secretariat.

The Carson Memo expanded the Hagel framework to include:

• Major Depressive Disorder (MDD)
• Anxiety disorders (generalized anxiety, panic disorder, social anxiety)
• Military Sexual Trauma (MST) and related diagnoses (PTSD-MST, depression following MST)
• Traumatic Brain Injury (TBI) (already covered by Hagel, but re-confirmed)
• Substance Use Disorders where the substance use was a coping mechanism for an underlying mental health condition
• Adjustment disorders
• Any other DSM-5 listed mental health condition that may have contributed to the misconduct

The Carson Memo's most significant expansion was its treatment of substance use disorders. Veterans who had been discharged for drug or alcohol violations had historically faced an uphill battle — substance use was treated as a character failure rather than a symptom. The Carson Memo directed boards to consider whether the substance use was a response to untreated mental health trauma, and if so, to apply liberal consideration.

Similarly, veterans discharged for personality disorders received additional protection under the Carson Memo. The memo specifically noted that personality disorder diagnoses in the context of service-connected trauma should be reviewed with particular scrutiny.

What "Liberal Consideration" Means in Practice

"Liberal consideration" is a legal standard of review — and it's more veteran-favorable than the prior standard in several concrete ways:

1. The Evidence Doesn't Have to Be Perfect

Under the prior standard, ambiguous evidence was interpreted against the veteran. Liberal consideration reverses this: when evidence is in "approximate balance" — meaning neither clearly supporting nor clearly refuting the connection between the mental health condition and the misconduct — the board must resolve the ambiguity in favor of the veteran. This is similar to the benefit-of-the-doubt standard that applies in VA disability claims.

2. No Contemporaneous Diagnosis Required

Before the Hagel Memo, veterans were often told they needed to show their PTSD was documented in their service medical records. Under liberal consideration, a current diagnosis from a qualified mental health professional is sufficient — as long as the professional can credibly connect the diagnosis to service-era events and explain how the condition contributed to the veteran's in-service misconduct.

3. "Contributed To" Is a Low Bar

The standard requires that the mental health condition "contributed to" the misconduct — not that it was the sole cause, or even the primary cause. A veteran who committed misconduct for multiple reasons, one of which was untreated PTSD, may still qualify. The condition needs to be a real contributing factor, but it doesn't have to have been the only factor.

4. The Boards Must Explain Denials

Under both memos, boards that deny upgrade applications citing mental health evidence must explain their reasoning in writing. This creates a record for appeal and makes it harder for boards to summarily dismiss mental health evidence without engagement.

The Nexus Requirement: Connecting Condition to Conduct

The single most important element of a PTSD/MST upgrade application is establishing nexus — the connection between your mental health condition and the misconduct that led to your discharge. This is where most upgrade applications succeed or fail.

The nexus argument has three parts:

1. The condition existed during service. You must show that your mental health condition — PTSD, MST-related depression, anxiety, substance use disorder — existed during your period of service, even if it was never diagnosed at the time. This is established primarily through a current mental health evaluation and professional opinion.
2. The condition was caused or aggravated by service. You must connect the condition to a specific in-service stressor — a traumatic event, pattern of abuse, combat experience, MST incident, or other qualifying event. This is the same nexus standard as VA disability claims.
3. The condition contributed to the misconduct. You must explain, with professional support, how the condition contributed to the specific behavior that led to your discharge. This is a narrative bridge that requires both professional testimony and your personal account.

A mental health professional's nexus statement should explicitly address all three elements. A generic diagnosis letter is not sufficient. The evaluating professional should review your service records, your personal statement, and buddy statements before writing their opinion — and their letter should specifically address the misconduct, the diagnosis, and the causal connection.

Evidence Package for PTSD Upgrades

A well-constructed evidence package dramatically improves your odds. Here is the optimal evidence stack for a PTSD-based upgrade:

1. Current Mental Health Evaluation (Private Provider)

Commission a full psychiatric or psychological evaluation from a licensed private-sector provider — psychologist, psychiatrist, or licensed clinical social worker with discharge upgrade experience. A private evaluation typically carries more weight than a VA evaluation because it is perceived as independent. The evaluation should include:

• DSM-5 diagnosis
• Professional opinion that the condition "more likely than not" existed during service
• Specific connection between the service-era stressor and the diagnosis
• Explicit statement that the condition contributed to the misconduct in question
• Review of service records, personal statement, and buddy statements

2. VA Records and Ratings (if applicable)

If VA has service-connected a mental health condition, this is powerful corroborating evidence. Submit all relevant VA records: the rating decision, C&P exam results, treatment notes, and any VA clinical assessments. A VA service-connection decision effectively pre-establishes that the condition is connected to service — the board cannot simply ignore it.

3. Personal Statement

Your own statement is a required and crucial element. Write chronologically: describe your service, the in-service stressor that caused your PTSD, the behavioral changes that followed, how your mental health affected your conduct, and what the discharge has cost you. Be specific about dates, units, and incidents. Be honest about the misconduct — boards expect you to acknowledge it; they want to see that you understand the connection between your mental health and your behavior. Aim for 3-6 pages.

4. Buddy Statements (Witness Declarations)

Statements from fellow servicemembers, non-commissioned officers, chaplains, or family members who knew you during service carry significant weight. Ask them to describe, in their own words, the behavioral changes they observed — not to make legal arguments, but to describe what they saw and heard. Useful observations include: changes in mood or personality, increased alcohol consumption, sleep disturbances, isolation, aggression, erratic behavior, or expressions of distress. These observations corroborate the timeline of your mental health deterioration.

5. Service Records Corroborating Symptoms

Pull your complete service records via SF-180 or milConnect. Review for: sick call visits for sleep, anxiety, or physical symptoms of stress; any mental health referrals or counseling; medical records mentioning behavioral changes; counseling statements reflecting declining performance; duty performance evaluations showing a decline around the time of the stressor; and any administrative actions that correlate with the onset of mental health symptoms.

• Private mental health evaluation with explicit nexus opinion — this is your anchor document
• VA service-connection decision for PTSD or mental health condition (if applicable)
• Personal statement — chronological, specific, honest
• 2–4 buddy statements describing observed behavioral changes during service
• Service medical records showing sick call visits, mental health referrals, or treatment
• Performance evaluations showing a decline correlated with the stressor period
• Any contemporaneous documentation of the in-service stressor (if available)
