There needs to be a briefing room for squadrons and the entire team. A room that is out of the tower so range doesn't affect the briefing, and one with the ability for the host to flag players to speak, players can "raise their hand" to let the presenter know they wish to speak. Open forum can be turned off or on for open discussion mode or presentation mode.
During many scenarios, some of us use a program called Twiddla and we all log in and look at real time mission planning map. We type on the map, draw routes, move plane icons around, highlight radar trigger points and much more. This would be a nice element to be included on the map as we brief. It's simpler and less time consuming to create the waypoints from a mission planner, as it's more free style and collaborative, everyone in the room could see it, and the ability to draw can be given to group leaders and others so as to have a collaborative discussion with visuals.
A very nice feature would be the ability to create Groups/Squads and drag the participants into the squads during the briefings, and as groups form, late comers attend, plans change and such, we could quickly and easily create the groups.
This would be helpful to many of us who actively plan and lead scenario teams.
