Having commands on board with the organizational staff would help in such large situations. They would be privy to scenario information and could help communicate this to players in order to keep them on task.
Also having the organizers set up and maintain a forum for such a large event is also important. It provides the organizationally minded to speak up, and for them to disseminate ideas to their teammates. Especially since for such an event to take place most players are from regionally disparate areas and have likely never played together.
As for lone wolves (individuals and squads) you can always count on them going to find a fire fight. Consider them suppressing fire or cannon fodder to allow the objective-focused squads to complete their tasks. The nice thing is that lone wolves always like to be told which direction the fight is in. I have no qualms about sending them into the thick of it! Maybe that is the Russian side of my tactics coming out.
