weapons (at least most of them) can only be unleashed upon targets in sight.

In the current game all units can shoot at enemies that are covered in shroud. The shroud or fog of war can only block view of the player but not the view of your units. While in more modern RTS games as Generals or StarCraft, enemies out of the sight cannot be fired upon, and "sighters" and "attackers" can be different units. For example, long-range artillery have a low sight thus cannot attack anything that is not displayed on screen, if your recon jeep spot any enemy within artilley's range, it will shell the enemy without the need of any order. This is already done in OpenRA. It would be nice if Ares can create this logic too, and, if better, create a tag to control whether a weapon behaves as forementioned, or as in vanila yuri.
