If want the propaganda version, you can find it lots of places. It’s baloney.
The real Warrior’s Creed (from Robert L. Humphrey):
Wherever I walk,
everyone is a little bit safer because I am there.
Wherever I am,
anyone in need has a friend.
Whenever I return home,
everyone is happy I am there.
Think about how it is we become that person, and what we have to sacrifice. Then think about how we project that image to the people around us. This is what I strive for.
