Marines' Hymn

The Marines' Hymn, also known as The Halls of Montezuma, is the anthem of the US Marines. It is heard playing on the Enclave Radio, and also in Fallout 4 after the Sole Survivor's speech on a recruitment radio beacon. The arrangement used in Fallout 3 was done by Kelly Richmond and was released in 1996 on the Sound Ideas CD Time Marches On. It was re-released in 2003 on the Westar Music CD Proud and Spirited (WSR 171).
