Once More Unto the Breach
Once More Unto the Breach (0:58) opens with a louder and graver rendition of the brass opening in The Battle Begins (from the earlier track Winter Contingency), followed by the choir singing a slower rendition of the vocals from the aforementioned track.

Meltdown
Meltdown (1:40) is a reprise of The Other Side (from the earlier track Exodus), featuring a more prominent brass as well as low strings over the original pulsing synth effects and a high tempo string melody.

Special Delivery
Special Delivery (1:39) opens with the percussion from The Battle Begins, accompanied by high strings ambience. Male choir fade in as the percussive beats become more complex briefly, and when the percussion fades out, strings return as ambience in accompaniment to the male choir.

The percussion plays when Noble Six mans the Mark 2488 Onager.

Production notes

 * The name Once More Unto the Breach alludes to the first Halo: Reach ViDoc released, Once More Unto the Breach, itself being a reference to the famous speech in William Shakespeare's play Henry V. The name is also used as the opening chapter of the level.
 * The name Through the Rock alludes to the rocky caverns before reaching the ship-breaking yards.
 * The name Shipbreaker alludes to the ship-breaking yards and the decommissioned.
 * The name Meltdown alludes to the melting of steel scraps in the ship-breaking facility.
 * The name Move Mountains is likely derived from the idiom and alludes to NOBLE Team’s mission to deliver the armored matrix to UNSC Pillar of Autumn in the Covenant-dominated Asźod region.
 * The name Noble Six is named after SPARTAN-B312’s designation within NOBLE Team. Fittingly, the piece is a variation of the character’s motif Lone Wolf. It may imply that by the time the piece plays in the penultimate level, the Spartan, as instructed by Carter in the the first campaign level Noble Actual, has discarded his/her Lone Wolf personality, and has adopted the role of a team member as “Noble Six”.
 * The name Special Delivery alludes to NOBLE Team’s mission to deliver the armored matrix to Captain Keyes. A track of the same name was featured in Halo 3: ODST Original Soundtrack.
 * The name On the Gun alludes to Six operating the Onager.
