Not everyone will develop PTSD. Of the ones that do, not all who develop it recognize it immediately. Of those, even fewer will seek treatment. Combat is not the only way to develop it. Some might only develop it after ruminating on events later on, or failing to adjust to civilian life. What's certain is that not treating PTSD can cause much bigger and more dangerous problems. And unless you're a doctor, I wouldn't throw 'fraud' around so easily.

It sounds like you're one of the ideal ones for your line of work, though; brains that are less susceptible to stress damage are rare. It's why not everyone is fit to become a police officer or give talks in front of big crowds. Others have an adrenaline sensitivity or a panic groove etched so deeply in their brains that they'll forget their names if you talk to them when they don't expect it.

I'm also assuming you entered the military voluntarily. There's a predisposition for certain brains to take on and thrive in certain careers. As a DWB friend of mine put it about the career mercs he treated, "They aren't psychopaths, just real mean sons of bitches."

You don't have to like people who aren't built as tough as you, but that doesn't mean they're faking.

I’m well acquainted with how ptsd works.

The vast majority of the people in the military are never exposed to anything at all. They do a job and they get paid for it. They’re no more likely to develop ptsd than the local grocer, plumber or electrician. Many of them are exactly a grocer, plumber, or electrician with a military ID card. They’re not “Mercs” any more than the local grocer...

Everyone on active duty today entered voluntarily as well.
