When you need to make restrictions for armies in briefings (especially important for coopera-
tive missions),use some simple keywords that will help you program your briefing.
Begin by writing the common things,like conditions of weather,dates,etc.ñ any info that is
the same for both sides.This part of the briefing will be displayed for all players (in both
Dogfight and Cooperative missions) before the keyword line .
Below are restrictions for armies.
Here you may place a short brief for all armies that is displayed before you select your air-
craft.It is possible to write nothing or to notify others to select their aircraft (in both Dogfight
and Cooperative).All the briefs below are not shown before you select your aircraft.Once the
aircraft or the position of multi-crew aircraft are selected,one of the briefs below will be dis-
played,depending on which side the aircraft was selected to play for.At the same time,the
text that was there () will disappear.
