These sappers would often then infiltrate through imperial lines in a number of missions. In some cases they would lay down demolitions to blow obstacles and clear a path for a Stygian attack force. other times they would detonate fuel depots and ammunition stores. In still other cases they would destroy artillery prior a major assault. Sappers quickly garnered the ire of any imperial force in theatre and were often executed on the spot when caught.
