"COVER" and PBEM LOS

[coltom]

I have enjoyed playing the CD version of your game for several years....as a new member of this forum I apologise if these questions have been answered in a previous thread. COVER..if I understand correctly moving into cover gives no benefit on the turn you move, some benefit on the next turn, and full benefit on the following turn. PBEM LOS...since you only see your opponent's units if you fire on him during his movement how do you overwatch (without firing) an area of the map with a FO for instance to observe him moving from a hex out of your LOS to another hex out of your LOS...in other words at some point during his movement you would have seen him but since he moved from a hex not in your LOS to another hex not in your LOS he has moved (closer) without you observing him (in game terms). Thanks for your reply in advance.
