This brings up a good point. If you could target any hex within your range(not just visible enemies), you could shoot at bushes or tall grass you suspect enemies to be hiding in. In other words, shoot into bushes you’ve seen enemies move into. Hold Ctrl before Left click while aiming ranged and reach weapons to highlight any hexes in your range.
