Walk onto any Marine Corps base and you'll hear all sorts of celebratory grunts, like "ERRR," and "Yut," echoing throughout the well-trimmed grounds. However, one grunt stands out the most amongst Marines from the day they enter boot camp until the day they die — "oo-rah."
Although the military has many slang words and uses countless acronyms that could mean virtually anything to a civilian ear, the battle cry, "oo-rah," has only one meaning.
Used as a motivational tool to push recruits and Marines beyond their limit, the classic grunt actually stems from another traditional sound.
Although they are a few theories how the legendary shout started, several sources point to a single origin — aboard a Naval submarine.
Many historians believe that "oo-rah" came from, of course, Marines, assigned to 1st Amphibious Reconnaissance while traveling aboard a submarine in 1953.
