Light 'Em Up (Kim Rye)
Blow up a silo after liberating Fall's End, and get a mission to blow up all the silos.
Of all the region-specific destructibles, silos are the easiest – they're huge, easy to spot, and you can even see their 3D models by zooming in on the world map. Find their specific locations below.
Note that this mission may not autocomplete after the last silo, especially if you're working on a different mission when it happens. Complete a few more missions or liberate the region to knock this completion loose.
