I think it was back in 2010-2011 that I attended a VCDS Group CWO`s conference where this was a discussion topic. The manifestation of PTSD among CFINTCOM personnel who viewed the RPV feeds in real time, including TICs where they would watch the battle unfold but could do nothing to influence the outcome, was completely unforeseen and unexpected. It was one of those "who knew?" moments.
Given that the DSM-V came out 2010/11 and the DSM-IV(TR) was out at that time, this should have been a "DUH" moment, not a "Who'd have thunk it?" one.
Exhibit 1.3-4DSM-5 Diagnostic Criteria for PTSD
Note: The following criteria apply to adults, adolescents, and children older than 6 years. For children 6 years and younger, see the DSM-5 section titled “Posttraumatic Stress Disorder for Children 6 Years and Younger” (APA, 2013a).
Exposure to actual or threatened death, serious injury, or sexual violence in one (or more) of the following ways:
Directly experiencing the traumatic event(s).
Witnessing, in person, the event(s) as it occurred to others.
Learning that the traumatic event(s) occurred to a close family member or close friend. In cases of actual or threatened death of a family member or friend, the event(s) must have been violent or accidental.
Experiencing repeated or extreme exposure to aversive details of the traumatic event(s) (e.g., first responders collecting human remains; police officers repeatedly exposed to details of child abuse). Note: Criterion A4 does not apply to exposure through electronic media, television, movies, or pictures, unless this exposure is work related.
Even if it hadn't been published at that point, the DSM-IV (TR) definition is more succinct:
Appendix E: DSM-IV-TR Criteria for Posttraumatic Stress Disorder
The person has been exposed to a traumatic event in which both of the following were present:
(1) The person experienced, witnessed, or was confronted with an event or events that involved actual or threatened death or serious injury, or a threat to the physical integrity of self or others.
(2) The person’s response involved intense fear, helplessness, or horror. Note: In children, this may be expressed instead by disorganized or agitated behavior.
