I was more thinking in a sapper role, with special abilities, reserved for a forward engineer unit like breeching obsticals, or even building ones, if the senerio called for it. More of a front lines, crawling through the mud with a bangalore torpedo, blowing holes in the wire, for the advancing assult forces type squad (?)
They could also be used to detect mines, or lay them, booby traps, big explosions, or building a school for poor orphans on epsilon 7 , that type of thing.
