The "orange" friendlies are those tuned to squad channel,or just on the same tunable channel,radio box "V".
The bullets,could be a flashing town,located near a base in yellow,by default. when an enemy is close but not in radar icon range the town can flash,a GV will cause this also.
If you open clipboard map and go to options,preferences, GUI, you can adjust the colors to suit your preferences,you can change the different countries colors,icon color for friendly,squaddies and enemies.
If you right click on map you will see a window open,select clipboard maps and you can view map layouts of the different bases,ports,headquarters,etc.
If you have any other question plz feel free to ask.
