To become a Crewman, just click the JOIN VEHICLE button in the Ready Room of a mission. Highlight the crewman you want and click SELECT CREW. A list of available Crewmen will be displayed. To become a vehicle Commander, reserve a vehicle by selecting it in the Ready Room, then click REQUEST CREW. When multi-crewing a vehicle, one player is the Commander and the other is Crew. Almost every vehicle in BATTLEGROUND EUROPE supports more this. Two players may work a single vehicle together using the Multi-Crew functionality. Select a combat unit from the available deployable forces if you haven’t reserved one already, and press the Enter World button. More often than not the combat chatter of your fellow soldiers fighting in the field can give you the most useful information before your boots hit the dirt. You also have access to the mission channel to chat with your mission mates here. You can select a combat unit and reserve it here while you get the lay of the land. Your primary goal in the Ready Room is to prepare for combat. Finally, the Mission Orders pane is the brief written by the mission leader. The Deployed Forces pane shows how many units of what type are spawned in and fighting. The Mission Details offer a review of the general info. The leader will be color-coded so that it is easier to identify him. The Briefing tab shows Mission Members and gives an indication if they are spawned in or not.
