Military Sexual Trauma (MST) Claims

What MST means in VA claims

Military Sexual Trauma is the term the VA uses for sexual assault, sexual harassment, or sexual threats experienced during military service. MST is not itself a diagnosis — it is a stressor that can give rise to PTSD, depression, anxiety, eating disorders, substance use, and other service-connected conditions.

Because sexual trauma is widely underreported in service, the VA recognizes that official records often do not document the event. Under 38 CFR § 3.304(f)(5), special rules allow alternative evidence ('markers') to corroborate the in-service stressor.

Accepted markers (alternative evidence)

• Records from rape crisis centers, counseling centers, or mental health providers (in or out of service).
• Statements from family members, roommates, fellow service members, clergy, or counselors the veteran told at the time.
• Requests for transfer to another military duty assignment.
• Deterioration in work performance — performance evaluations declining after a specific date.
• Substance abuse, depression, anxiety, or panic attacks documented after the event.
• Episodes of unexplained economic or social behavior changes.
• Pregnancy tests, sexually transmitted infection tests, or unintended pregnancies.
• Increased use of leave or unauthorized absences.

How MST claims are evaluated

When markers are present, the VA may concede the in-service stressor without requiring direct documentation of the assault. A C&P examiner — typically a mental health clinician trained in MST — then evaluates whether the diagnosed condition is at least as likely as not related to the MST.

This is a more flexible standard than typical PTSD claims. Combined with the wide range of accepted markers, MST claims have a meaningful path to grant even when official service records are silent.

How MST claims are evaluated

1. Identify the conditions you are claiming — most commonly PTSD, but also depression, anxiety, eating disorders, sleep disorders, and substance use disorders.
2. VA Form 21-526EZ is the typical application form for this claim. You may also use VA Form 21-0781a (Statement in Support of Claim for PTSD Secondary to Personal Assault), which is specifically designed for MST cases.
3. List markers you can document — names of people you told, post-event medical visits, performance evaluation changes, transfer requests, etc.
4. Submit lay statements from people who knew you before and after the event. They do not need to know the specifics — observations of behavioral or emotional changes count.
5. Attend the C&P exam with an MST-trained examiner. Honest, specific descriptions of symptoms and their impact carry significant weight.

Conditions commonly secondary to MST

• PTSD (the primary claimed condition in most MST cases)
• Major depressive disorder
• Generalized anxiety disorder, panic disorder
• Eating disorders
• Substance use disorders (when the use is a coping response to the trauma)
• Sleep disorders, including insomnia and nightmares
• Sexual dysfunction
• Chronic pain conditions and somatic disorders

Where these claims break down

• ×Believing the claim cannot succeed without a police report or formal complaint — the VA does not require that.
• ×Not documenting markers — even small details (a transfer request, a medical visit) strengthen the claim.
• ×Filing only for PTSD when depression, anxiety, or substance use are also present.
• ×Not requesting an MST-trained C&P examiner.
• ×Believing the case has to be re-told repeatedly — once the stressor is conceded, the focus shifts to current condition severity.
