Helljumpers' anthem

The Helljumper's Anthem is the official anthem of the ODST.It is described to have "hyped up strains".

Mentions
In Halo: The Flood, an ODST places a small disk into his or her data player and plays the anthem over the team frequency on the jump to Alpha Halo. Neither Lieutenant Melissa McKay or Major Antonio Silva tells the ODST to stop the track, so McKay concludes this is the right time to play it.
