Cerberus combat engineers are specialized support units that assist primary forces while staying out of the line of fire. They wear lighter armor than the typical Cerberus combatant, using a modified mesh that allows greater mobility. Under cover and out of sight, engineers focus on setting up and maintaining turrets as well as repairing mechanical units or armored allies. When confronted, they return fire only for as long as it takes them to find cover again and let front-line combat personnel take over.
Although engineers are not particularly dangerous on their own, the Alliance specifically warns troops to remain alert for turrets, which can mow down an entire squad while the engineer escapes.
