Tips from the Frontline

[RNL Tiger]

Red lines are outgoing fire, yellow lines are incoming fire....is that what you're talking about? Doesn't have anything to do with LOS/Spotted/attack.

Thanks for that clarification; yes, that is one part of the question. The other part is how do you know if an enemy unit still has LOS to your friendly unit as opposed to the enemy seeing a "spotted marker" i.e. unit was seen there but is not in the enemy view currently.
