The Marines Hymn

The "Marines' Hymn" is the official hymn of the United States Marine Corps. It is the oldest official song in the United States military. The "Marines' Hymn" is typically sung at the position of attention as a gesture of respect.

The music is from the Gendarmes' Duet from the opera Geneviève de Brabant by Jacques Offenbach, which debuted in Paris in 1859.
