Line-of-sight

line-of-sight, LOS, L.O.S., n. 1. in general usage, a line from an observer's eye to a distant point. 2. in wargames, a line measured from one miniature's hex to another; the unit may only track or fire upon another other unit if the line-of-sight is unobstructed. 3. refers to the ability to target an adversary.
Ex: "I want to fire my cold ray at The Masterbrain. Do I have L.O.S.?" "No, he's hiding behind an overturned tank. But I'll let you do an AOE attack." [GJ1]
