Using arty/mortar spotters

[Minuteman]

For mortars, yes - not for spotters, though. Select the mortar unit (obviously must be w/in command radius of leader) and select the target command. As you move the LOS line around, you'll notice that it is blue when preparing to fire where the unit has LOS. It will go to the orange/black LOS line when the unit can't see, however, pay attention to the writing beneath the end of the line. If it says "Area Fire" instead of "Sight Blocked" that tells you that there is no LOS for the mortar, however it can fire there because of the leader's LOS.
