Nah if actually everyone shuts up in Group chat and let's only the Camera Ship talk, then everything should be fine xD.
The max thing that someone would write in Group would be "Give me new orders" once finishing an objective.
All you have to do is write small commands that explain alot. *Group Target* "Capital Ships engage this target." *Another Target* "Snubs get these Bombers."
The Players pretty much can just check out at what he's pointing at and engage the targets. If the Camera Ship Player figures it was a bad idea he can say "Back out to C4" on the Navmap maybe.
After a significant amount of Battle he can maybe call in the Fleet he has been holding back since the beginning of the event in another Sector on the Map and call them in for battle. That's gonna be all up to the player flying the Camera Ship.
Only there will be "Global Commands" like "Strict Follow" and "Auto Follow" that every player would need to know on which mode they've been set to. I suppose following the Command of the Camera Ship player wont realy be hard if he explains clearly who has to engage what and what to do exactly, the next steps. Especially if only the Player is going to type mostly in Group.
We can name those Camera Ships "Player 1" and "Player 2" or something obvious to know that it's one of the Players.
You mark one group target then type which Ships are going to engage it, I suppose a Carrier Player wont have the issue in figuring out if the player actually means him if he says "Carrier attack this target!" right? : D
