You all know im a super noob.
Right here goes, in the game do we all do are own thing?
Is there a correct chain of command?
you know were im going with this so rather than list 20 questions can some one tell me how CiA events usually unfold???
You'll get given general orders in functional sections which can reform into other sections depending on regens etc.
Orders throughout the day will be given to section leaders who will disseminate.
Nothing complicated, just do generally what you're told and don't shoot your own players and you'll be fine.
Any further questions can be answered by my No1, Kermit!

This is a Gunman event rather than a CiA one , so the gameplay is led by Captains/Marshalls who are Gunman staff on both sides . This ensures that the gameplay is kept going and that the event doesn't bog down . They can also perform special game tasks, and help deal with players comfort etc . CiA events work along similar lines but because they are smaller the organisers tend play the command staff themselves.
ORBAT will be arranged on the day , generally people will be split into squads with their mates. Missions will be explained in breifs given by your commanders at the start and during the day .
