[Warfare] gameplay features

[muniek85 10]

Hey. I have another pack of questions:

1. What parameter of the server settings is about "unknown" and "enemy" units showing up on global map as orange and red dots while spotted by my squad soldiers?

2. Why on some servers parameter "spacebar scanning" (i guess thats the green or red "rifleman" etc. marks on units that i target and press spacebar?) is shown as "enabled" and it is not working?

and side questions:

3. Is it normall that european Warfare servers are all empty at early hours, and there is only like 5-9 of them in totall? (thats what my server browser shows)

4. What ports does ARMA:OA uses?

Thanks in advance for answers.

Regards

Muniek
