In general, exposure to stressors can take three forms. The first is engagement in combat operations while on active duty, the second is non combat experiences such as plane crashes, an automobile accident or other non-combat traumas, and the third is personal/sexual assault.
Establishing exposure to stressors is accomplished in one of two ways. First, is the receipt of awards/decorations while on active duty which confirm engagement in combat operations while on active duty. Such things as a Combat Infantry Badge, Combat Action Ribbon, Purple Heart, Silver Star, and Bronze Star with V Device can confirm the veteran was exposed to combat operations. If you have received one of these awards/decorations the VA considers your exposure to stressors confirmed and no further action is necessary by the VA or you to establish the stressor element of the claim for PTSD.
If you did not receive one of the awards/decorations confirming engagement in combat operations, the law requires you must provide “stressor information” to the VA so they can attempt to verify your exposure to combat stressors. If this is the case, there are some very important things you should know about providing this information. First, the stressor information must be as specific as possible. Specificity means date, place, unit and nature of the stressor must be provided in your statement of the claim to the VA.
