Follow Our Brothers is a song included in the Halo 3: Original Soundtrack. It plays during the levels Crow's Nest, Floodgate, and The Storm. It is also the background track for the cutscene at the end of the level Floodgate.

The song begins with a slow, single-note melody of strings. Higher strings then join in with a single note. The motif is then repeated with choir in the background. The song then switches to a minor key, still retaining the same, slow melody. The strings melody then fades, to be replaced by a more rapid motif. At the end, the music once again fades into a calmer version of the beginning of Last of the Brave from the Halo 3 Original Soundtrack

Note: The beginning of the song sounds very similar to Under Cover of Night from the Original Halo Soundtrack, and the song's name (and the second half of the song) mimic the Halo: Combat Evolved song, Brothers in Arms.

It runs for 3 minutes and 25.531 seconds (3:25.531).
