i agree with bebop.
i was never in the military, etc. but observed my son,3 x iraq, with combat ptsd and my brother, a nam vet. both had to work thru the rage first, then they slowly reached out. in my brother's case it took about 30 years but today he is better. my son was able to talk about what he endured much quicker and thus he improved much quicker but we never pushed him. he needed to do it in his on time.
as you know from my previous posts to you, what worked for my loved ones was our being there to listen when they were ready to "vomit' up all the pain, trauma, etc. so it was a gradual thing for them.
i'm not sure if bombarding a person with combat ptsd would help. why? i think it would put a person's mind on over-drive, IMHO. why do that when safer, kinder means can be used?
this is just my opinion on the question. i'm sure there will be others who may feel differently.
