"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[1] are specialized UNSC servicemen that perform construction and demolition tasks during combat.


Combat engineers are personnel who are tasked with construction of allied fortifications and demolition of enemy emplacements.[2] A number of dedicated MJOLNIR powered armor suits are designed for, and available for the use of combat engineering including the Technician, Indomitable, the synonymously-named Engineer and the OSTEO. The Assault/Sapper armor accessory is additionally available for Spartans as an attachment to their armor.[1] The ODST/DEMO armor set is also available for ODST combat engineers.[3]

During the Fall of Reach, Spartan Emile-A239 employed the Assault/Sapper armor accessory for his B-class Mjolnir.[1]

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.[5][6][7] Several engineers would be deployed on Draetheus V itself.[8]
