The term Jarhead

I’ve been out of the corps for 15 years now, and still one of the most common terms I hear used by civilians and other service members is “jarhead.” Many of you take it as an insult, as when it is used, it’s meant to impart the idea that we’re all empty vessels.
I’m here to tell you that it is not.
An empty mind is a dangerous one, and I’ll tell you why. Someone preoccupied with anything other than the direct threat in front of them has already lost half the battle. If your mind is clear, it is more readily prepared to respond to the unexpected. The idea is that your training takes over, when your mind doesn’t have enough time to process. It’s like that old guy said in “the Last Samurai.”
He said “too many mind.”
The only thing that matters is your enemy. Stop thinking about who he is, what your family might think if you don’t make it home. You can’t afford to waste precious microseconds considering these things.
Empty your mind, jarhead, and your body will take over. You are trained for this, born for it.
Heed my words junior Marines, it may save you one day soon.
Obviously, educate yourself as much as possible. Reading creates a sharp, analytical mind. But when it’s time to get blood on your hands, stop thinking. Lean into your jarhead side. It knows what to do.
Godspeed and semper fi, you devious canines.
