1. Go to the Leader of one of the other teams where the marker is pointing
2. Speak to him and you will get to the breefing with Captain Miller
3. Afther he finished you get in front of the ammoboxes to rearm before the mission.
4. You cant move or klick on anything and have to restart the mission of the camp. Only selecting the mission directly from the Map behind Miller, listen to the breefing (and you can skip that without any problems) and the game will guide you directly to the mission and you can klick start the mission.
