It's a little late, I know, but I wanted to put in my two cents on this issue. I really feel like this issue has gotten way out of hand as this thread has three pages and the thread discussing the actual house only has one. I would like to preface this by saying I have no military training or experience (I have, however, gotten the opinion of my best friend of 20 years who just got out of the USMC after doing two tours in Kuwait totaling 13 months). His opinion, which I share, is that anyone with PTSD/Shellshock knows that they have this condition and are being treated. They probably avoid events like HHN in general to avoid being startled and having to resort to the military "fight or flight" instincts. My father-in-law (who served 26 years as part of Miami-Metro Dade police) avoids the event for the exact same reason.
My friend's opinion is that USO should continue posting warnings like they normally do. He doesn't see any reason to single out military personnel, but feels a general "This house has scenes with graphic war violence, if scenes of such nature will adversely affect you, please do not enter" would suffice as people who have never seen military combat may be affected by the scenes as well. He doesn't feel that any "extreme precautions" need to be taken in regards to scareactor safety or OPS is concerned in this house since (as history has proven) the drunks/ easily startled/ generally douchebaggy guests attempt to harm scareactors in every house of every theme every year.
Finally, in regards to people "checking out" the house to make sure it's ok for veterans or current military personnel alike, I disagree completely. This is the only example I can use to back my reasoning: I have stated publicly that I have a neurological disorder/ brain defect that causes me to have seizures. I wouldn't want someone with Epilepsy (or any other seizure disorder) "judging/checking out/okaying" a house with heavy strobes or other seizure triggers for me, since what triggers their seizures may not be the same as what triggers mine. No offense, but I certainly wouldn't want someone along the lines of an EMT, having never experienced a seizure but having studied them a great deal and knowing their causes and warning signs, going through a house and telling me it's "all clear." I would find this not only offensive, but insulting as well, to be lumped in to some generic category of "seizure people" who seem to have no personal control or knowledge of their condition.
