Sometimes I want to dial down the range on a specific turret to only defend a smaller chunk of land. This lets me carve out more specific spaces to defend, use lakes to my advantage, etc.

I could also use this to set all the ranges on my turrets, upgrade the turret range science, then one-by-one clear out the area they would cover and dial up the range on each one as I clear in advance of it. (The swarm of targets as an upgrade hits can be a bit much)
