A tug is any reusable propulsion/guidance bus that can be refueled in orbit and reused rather than discarded. At one point ULA had plans for ACES based hydrolox tugs and depots.

Ironically ULA could get a huge piece of that market if they got depots working. Nobody else in the world does hydrolox upper stages like they do and the RL-10 is, as mentioned ITT, a fantastic vacuum engine. It takes really big nuclear-electric systems for a space tug to get better than hydrolox chemical.
