OK. I believe the answer is the GS/localizer and VOR respectively.


Why did you choose VOR for the VOR/DME RWY 15 at MTN? Do you see VOR
serving the same role there as the localizer does for the ILS/DME RWY 2 at
DRO?

I chose it because it's the point where the rest of the required
information (distance to maintain from and radial crossing) is derived
from.

For the arc portion of the DRO approach, no - the DRO VOR serves the
same purpose for that approach until hitting the lead radial.
