Far Cry 5

This can be achieved by destroying Shrines, Silos or Wolf Beacons in each region.

Jacob's Region you need to destroy one Wolf Beacon (there are 10).
Dutch's and Faith Region you need to destroy one Shrine in each (2 in Dutch's 16 in Faith's).
John's region you need to destroy one Silo (there are 14).

The easiest way I found to do this was buy either a plane or helicopter with a machine gun (I prefer the helicopter because you can hover with it making it easier to aim) and fly it at night. The Silos are big and red so they are hard to miss. The Wolf Beacons have a bright red light on them that is easy to spot at night while the Shrines glow green at night. While using the helicopter or plane just fly up a bit so you can see a good portion of the land and fly to each region. After spotting one just fly over and shoot it with the helicopter/plane until it explodes. Once you destroy one in each region the achievement will pop
