If you're into mapping and want to make a co-op mission with briefings and the whole hit.. but you DON'T want the two armies reading each other's briefings, you can write it so that the actual mission brief turns up only after selecting an aircraft...
To do this, in the bit where you actually write the briefing in the FMB, enclose the separate bits in tags: <ARMY RED>brief here</ARMY> with the red being substitued for blue, green, pink with yellow spots etc. To make a common welcom message that disappears when you select a base/aircraft, enclose it in the <ARMY NONE> </ARMY> tags.
This way you can have a common welcome message and a separate briefing for each army.
