If a DS player saddles my 3-Force unit with Fear, can I use Unwavering Resolve to bring those orbs back into play for one Force struggle?

Indeed you can. Fear prevents the unit from committing to the force, but Unwavering Resolve does not involve committing the chosen unit to the force (and actually must choose a unit that is not committed) so the effects do not contradict each other at all.

That's what I thought!
