Engineers were specialist personnel in the Army of the Neo-Infinite Empire who were trained to operate and maintain a variety of vehicles and equipment. Engineers were recruited from volunteers that had a background in the field of engineering, physics, or mechanics, and were mainly tasked with operating and maintaining combat vehicles. Another duty was to set up Rakatan military facilities on different worlds and keeping the troops' weapons in good shape. However, driving vehicles, such as the Yorus Tanks, was their primary job. In some battles, regular Crusaders were drafted into engineering units and taught how to pilot tanks, though they would not remain in that position permanently.
They wore modified light armor and the regular Crusader uniform underneath, and were issued with more tools than weapons, fitting their role as combat engineers.
