S'funny, the vets I know who've seen the elephant tend to fall into two loose groups. The first have nothing to do at all with gun games, or guns for that matter. The second tend to be rather quiet and low profile, and absolutely deadly. Neither group does much talking about some things.
Still in touch with two buddies from that time. Both live in Northern Ca, one's just been rehabbed into a computer job, the other lives up past Yreka and farms. The farmer hunts and fishes, the other is a city boy. Both get pensions for physical probs and PTSD.Both have guns,shoot them informally for practice, and are w/o a doubt, very good with them. Besides the usual VSMs,etc, We've at least 2 Purple Shafts, and a Presidential Unit Citation. Neither does any games per se, tho one is starting to shoot a bit of trap.
Switching the subject, I quite shooting IPSC long ago, the day I first saw someone win with a handgun I wouldn't carry on the street. Some of those folks are excellent shots, but the idea of standing in plain sight and engaging a foe just upsets me no end. Some habits are easy to acquire. Finding cover when fired at became a lifelong habit milliseconds after my first incident began.
My committment to being as capable as possible for those luckily rare incidents led right here, 30 years later....
Sometimes I wonder if the expertise that comes with practice and proficiency in games is worth the bad tactics and mindset the various Combat Oriented games give.
