Both civilian and high poly campaign units exist in the SC2Campaign module(s). You need to add these modules as dependencies to your map in order to use them.
To do this:
1. File > Dependencies > Add Standard
2. Check Liberty (Campaign) and Liberty Story (Campaign)
With the Units layer selected (on the main map):
Civilian units will show up under Campaign > Terran > Units
High Poly units will show up under Storymode > Terran > Character
