MilitaryTimes has a story on a lawsuit filed by a Marine seeking relief for PTSD caused by training:

SAN DIEGO — Jesse Klingler joined the Marine Corps to serve his country and fight the bad guys.

But his enlistment as a rifleman was cut short after he was wounded in a super-realistic 2004 training exercise at Marine Corps Air Station Miramar’s Camp Elliott, during which he was taken hostage, tied and bound. Then, a hired actor — playing the role of an insurgent — pointed a very real AK47 assault rifle near then-Pfc. Klingler’s thigh and fired the hot gases from two blank rounds into his flesh.

Klingler, now 21 and medically discharged from the Corps, said he suffers post-traumatic stress from the incident and constant pain that he fears will prohibit him from a normal working life.

...

But to Strategic Operations Inc., Klingler is an opportunist and a malingerer: a young man with a slight wound who exaggerated his injury, found a way out of the service and now is suing the contractor for several million dollars.

Comment: Johnathan Shay, author of Achilles in Vietnam and Odysseus in America has advocated that tough realistic training is a protective factor against combat stress injury. Dave Grossman, author of the Pullitzer Prize nominated book On Killing has promoted the use of Simunition in training. One way to look at this situation is that it was an accident that resulted in threatened death or serious injury. Is it possible that training could cause a stress injury like this? More research is needed to look at the utility of realistic training. Can it actually provide mental armor against combat stress injury? Are there risks involved?
