A Few More Quick Questions

[JohnS]

As I said in my earlier post, just getting back to SP after a 20 year layoff and really enjoying it. Also, let me thank everyone who answered my earlier "Quick Questions". I have now looked much more deeply beyond the initial manual pages and see that many of my questions were answered deep within the documentation and I do thank you guys for your courtesy and "tolerance". Hopefully these questions are not as basic.

re "Cover" - I read the manual and (I think) all of the posts. Let me ask about your experiences with Cover

1) Does it seem to reduce the friendly unit's line of sight in any manner? (I know it has the possibility of hiding the friendly unit from the enemy LOS).
2) Does it seem to affect or reduce the unit's opportunity fire - either the amount or the decision to fire?
3) Any effect on the reception of artillery fire - less damage?
4) If the unit has fired upon an enemy unit and thus "targeted" that unit, does it seem to lose the target by going to cover?
5) Any effect on the unit's present or subsequent suppression that you can see?

Also - when I look at the screen and see that my unit can see 5 enemy units, is there any way (Hot Key?) to scroll through the enemy units to identify exactly which units are seen? I tried the "T" key but it seems to stop at the nearest unit and not go beyond. Am I missing something?

Also - tank riders - is there a time frame within which this can and cannot be done - example - Germans cannot do it before 1944?

Thanks for any help.
