[CQC_con-tact*]

I have done this before but i have no idea what i hit!! and i will try and explain this the best i can for example if i was playing as a fighter and i had my way points on the map and i had a buddy flying in a different unit playing as a bomber how could i add his waypoint to the map as well so all waypoint are on the map for all to see....
