Military sexual trauma (MST) is a term used by the Department of Veterans Affairs and by the military. MST refers to any type of sexual assault, (including sexual harassment), that occurred while the survivor was in the military. MST can happen to any service member during times of war, peace, and even during military training activities. In addition, the perpetrator can be a civilian or a service member and be of the same gender as the survivor (Nelson, 2012).
