Normal people run or hide when they hear gunfire.
That's what every instinct in your body tells you to do. Get away. Don't get harmed. Preserve life.
We don't. We charge the ambush, run towards the gunfire, protect the innocent, and return aggression with aggression.
This is a big enough challenge for the military, but for the law enforcement officer it is even a scarier proposition - If they don't get to the attacker, innocent unarmed civilians will die. Furthermore, they are often outgunned and don't have the benefit of true ballistic body armor. But they don't have a choice and they wouldn't have it any other way.
One of my best friends, now an elite operator, put it better than I have ever heard it put after his first trip to Afghanistan in 2001:
When the enemy starts firing from their ambush positions, they expect you to run, they expect you to cower, and they expect you to die. They do not expect 210 pounds of assaulter running straight at them firing precisely, alongside three equally physical specimens, looking like the four horsemen of the f*cking apocalypse, with a ton more guys right behind them. The message we send is simple: You want to kill me bro You want to kill my boys You're gonna have to f*cking earn it. Cause we sure as shit aren't backing down.
If you look closely at the news you see it every day: the Iraq vet that charges the guy with the pistol in the airport. The Afghanistan vet who disarms a knife attacker. The off-duty cop who stops the guy in the convenience store robbery. It isn't that these heroes aren't afraid. It isn't that they don't value their lives or that they are brainwashed. It's that they understand the reality of the world.
There are only two options in life. Fight or flight.
Most people run. Almost all people run. But not us.
The difference between us and everyone else is that we run towards the gunfire.
And that's the only difference that matters.
