I call the Marine Corps the biggest brotherhood in the world. No matter where we are, when a jarhead sees another jarhead with USMC cover (hat), sweatshirt, jacket, tattoo, or ring we always acknowledge them with a big SEMPER FI.
Race, religion, skin color or status in life has no place in the Marine Corps ranks; we are all just jarheads.
All of mankind should use the Marine Corps as an example of how people coexist in harmony. At least that is the way it was when I served. Hopefully the camaraderie is not changed.
