How often do PTSD treatment studies include military samples?

How often do PTSD treatment studies include military samples? Those who serve in the military are at risk for certain types of trauma. If military service includes a deployment or service during a war, traumatic experiences are more common. And, military-related trauma is not limited to combat, as accidents and sexual violence during service (military sexual trauma or MST) also occur. The willingness of Veterans and service members to participate in research helps the field learn which PTSD treatments work. At the same time, trauma and PTSD are not limited to those who served in the military. People who are not in the military (civilians or community members) live in war zones. Also, other traumatic events--like natural disasters, severe accidents, physical and sexual violence--are not military related.
