Military Sexual Trauma (MST)
Understanding Military Sexual Trauma
Military Sexual Trauma, commonly referred to as MST, is a term used by the Department of Veterans Affairs to describe sexual assault or sexual harassment that occurs during military service. MST can happen to anyone regardless of gender, rank, branch of service, military occupation, age, sexual orientation, or background. MST can occur during training, deployment, active-duty service, National Guard service, or Reserve service.
MST is not defined by where it occurred, who committed the act, or whether the incident was officially reported. Rather, MST refers to the experience of sexual harassment or sexual assault during military service and the lasting impact it can have on an individual's physical, emotional, psychological, and social well-being.
For many survivors, MST represents more than a traumatic event. It often involves a profound violation of trust within an environment where teamwork, mutual support, and unit cohesion are essential. When the perpetrator is a fellow service member, superior, or trusted colleague, the experience can affect a person's sense of safety, trust, and identity long after military service ends.
​
Military Sexual Trauma by the Numbers
Military Sexual Trauma affects both women and men.
​
According to Department of Veterans Affairs screening data, approximately 1 in 3 women Veterans and 1 in 50 men Veterans receiving VA healthcare report experiencing MST during military service. While women experience MST at higher rates, men account for a substantial number of MST survivors because men make up a larger portion of the Veteran population. Nearly 40 percent of Veterans who disclose MST to the VA are men.
​
Research examining military personnel and Veteran populations found that approximately 16 percent reported experiences consistent with MST. Studies indicate that sexual harassment is reported more frequently than sexual assault, though both can have significant and lasting effects. Researchers also believe MST is underreported. Fear of retaliation, concerns about career consequences, lack of trust in reporting systems, shame, self-blame, and fear of not being believed can prevent survivors from disclosing their experiences.
​
Why MST Often Goes Unreported
Many survivors do not report MST at the time it occurs.
​
Military environments are unique. Service members depend upon one another for safety, operational effectiveness, and mission success. Reporting misconduct may feel overwhelming when survivors fear damaging relationships within their unit, affecting career opportunities, or facing retaliation.
​
Some survivors worry that others will not believe them. Others fear being blamed for what happened or being viewed differently by peers and leaders. In some cases, survivors may attempt to minimize or suppress the experience in order to continue functioning within demanding military environments. Years or even decades may pass before a survivor speaks openly about MST. This delayed disclosure does not diminish the reality of the experience or its impact. In fact, many survivors report carrying the effects of MST long after leaving military service.
​
The Lasting Impact of MST
Every survivor's experience is different.
Some individuals experience symptoms shortly after the event. Others may not recognize the effects until years later. Trauma responses vary depending on the nature of the event, available support systems, previous experiences, and individual coping mechanisms.
​
MST may affect:
-
Mental health
-
Physical health
-
Relationships
-
Employment
-
Trust
-
Self-esteem
-
Sleep
-
Social functioning
-
Overall quality of life
​
Many survivors describe feeling disconnected from others, struggling with trust, or experiencing difficulty feeling safe in situations that remind them of the trauma. These reactions are not signs of weakness. They are common responses to traumatic experiences.
​
MST and Post-Traumatic Stress Disorder (PTSD)
One of the most common conditions associated with MST is Post-Traumatic Stress Disorder.
Survivors may experience intrusive memories, nightmares, hypervigilance, anxiety, emotional numbness, avoidance behaviors, irritability, and difficulty concentrating. Research suggests that MST is associated with PTSD symptoms at rates comparable to or greater than those associated with combat exposure in some populations. For some Veterans, everyday situations can trigger reminders of past trauma. Crowded environments, authority figures, certain locations, or interactions that resemble aspects of the original event may provoke emotional distress.
Without appropriate support, these symptoms can affect relationships, employment, education, and overall well-being.
MST, Depression, and Anxiety
MST is also associated with increased rates of depression and anxiety.
Survivors may struggle with persistent sadness, feelings of worthlessness, excessive worry, emotional numbness, guilt, or shame. Many report feeling isolated and disconnected from family, friends, or community members. Depression and anxiety can influence every aspect of life, from personal relationships to professional responsibilities. They may also contribute to sleep disturbances, reduced motivation, and difficulty experiencing joy or fulfillment.
​
Understanding these connections is important because recovery often requires addressing both the trauma itself and its broader emotional impact.
​
MST and Suicide Risk
Research consistently demonstrates a relationship between MST and increased risk for suicidal thoughts and behaviors.
Studies involving women Veterans found significantly higher rates of suicidal ideation among those reporting military sexual harassment or sexual assault compared to those without MST histories. Researchers believe that trauma, depression, PTSD, social isolation, and feelings of shame may all contribute to increased vulnerability.
It is important to emphasize that experiencing MST does not mean a person will experience suicidal thoughts. Many survivors recover and build healthy, meaningful lives. However, understanding the relationship between trauma and suicide risk helps communities identify opportunities for support and intervention.
​
MST and Substance Use
Some survivors turn to alcohol or drugs in an attempt to manage emotional pain, anxiety, sleep disturbances, or traumatic memories. While substances may provide temporary relief, they often worsen symptoms over time and can create additional challenges involving health, relationships, employment, and recovery. Substance use should never be viewed as a character flaw. Instead, it is often a sign that an individual is struggling and attempting to cope with overwhelming emotions. Addressing both trauma and substance use together often produces better long-term outcomes.
​
Healing and Recovery
Recovery from MST is possible.
Healing does not mean forgetting what happened. Rather, it involves learning how to process the trauma, reduce its impact on daily life, rebuild trust, strengthen relationships, and move forward with a renewed sense of purpose and control. Recovery looks different for every person. Some survivors benefit from individual counseling. Others find support through group therapy, peer support, faith communities, wellness practices, family support, or a combination of approaches. There is no single correct path to healing. What matters is finding support that feels safe, respectful, and effective.
​
The Importance of Peer Support
Many survivors describe isolation as one of the most difficult aspects of recovery.
Peer support helps reduce that isolation by creating opportunities for connection with individuals who understand military culture and the challenges associated with military service. Peer support is not clinical treatment, but it can provide encouragement, validation, resource navigation, and meaningful human connection. For Veterans who feel alone in their experiences, peer support can serve as an important bridge toward healing and recovery.
​
Supporting MST Survivors
Supporting survivors begins with listening.
Survivors often benefit from being believed, respected, and given control over their own healing journey.
Helpful responses include:
-
Listening without judgment
-
Respecting boundaries
-
Avoiding blame
-
Encouraging support when appropriate
-
Allowing survivors to share at their own pace
-
Recognizing that healing is not linear
Every survivor deserves dignity, respect, and access to support.
​
Moving Forward Together
Military Sexual Trauma remains a significant issue affecting service members and Veterans across all branches of service. While the effects can be profound, MST does not define a person's future.
Through awareness, education, trauma-informed support, peer connection, and access to appropriate resources, survivors can heal, rebuild trust, and move forward.
-
No one should have to carry the weight of trauma alone.
-
Recovery is possible.
-
Support is available.
And every survivor deserves the opportunity to heal.
