Combat engineer

"Broadly speaking, sappers are equally at home building things as they are blowing them up."

- Halo: Reach Armory description - Assault/Sapper

Combat engineers, also referred to as sappers are specialized UNSC servicemen that perform construction and demolition tasks during combat.

Role
Combat engineers are personnel who are tasked with construction of allied fortifications and demolition of enemy emplacements. A number of dedicated MJOLNIR powered armor suits are designed for, and available for the use of combat engineering including the Technician, Indomitable and the synonymously-named Engineer. The Assault/Sapper armor accessory is additionally available for Spartans as an attachment to their armor. The ODST/DEMO armor set is also available for ODST combat engineers.

History
Early in the Human-Covenant War, the 24th Marine Engineering Brigade were deployed onto Mesra to perform a number of critical asset-denial operations on the planet's xenotime mines.

During the Fall of Reach, Spartan Emile-A239 employed the Assault/Sapper armor accessory for his B-class Mjolnir.

During the Battle of Draetheus V in 2555, UNSC combat engineers assisted Spartan Edward Davis in destroying a Forerunner structure on the moon of X50. Several engineers would be deployed on Draetheus V itself.
