Some gameplay questions and a couple not

[Wdll]

Thank you all for your answers.
I am still a bit confused about the APCR and the ACC and the KILL values. Also the PEN : XX:YY the first number is at distance 0 and YY at max?
The ACC is percentage? The APCR is straight value?
What about KILL? What does it mean a 9:0 value?

I ordered the game, CD and all, a couple of days ago. Don't know how long it will take to arrive in Greece, but here is hoping.

Do you know if it is possible to continue an on going campaign with the retail version or do I have to finish it with the free version?
Do I have to uninstall the free version before installing the full?

I am excited about the game and my eyes are more. 800x600 on a 24" widescreen monitor is not THAT good. Pity there is no support for 16:10 resolutions, but lets not forget how old the game is.

Oh yeah, and do your units choose automaticaly what ammo/round they will use or can you actualy let them know what you want?

Again, thank you for the replies.
