A line of sight is an imaginary line drawn between a unit and the object of its attentions. It is used by the computer to determine whether a unit can see something that's possibly hidden behind an obstacle (and therefore displayed to the player). Range attacks and some spells require the target to be in the line of sight of the shooter or the spellcaster.
