I haven't read all this but here's my two cents and is probably not gonna implemented.
Force player to follow a squad leader, like in BIA where you press a key and they follow you, or you can tell them to take cover, charge, supress, move to somewhere, and select certain teams. But my idea is to initally assign players to Squad Leaders, then to force them to follow their orders. The squad leader will give comands, for instance, if he wnats you to move behind that hedge, on his screen he will cycle through squad members, and hold another key to show the spot where you should move. If he wants to tell you something specific, he can tell you over VOIP. On the squad members screen it will show him where to go, in tis case behind the hedge, indicated by some symbol of some sort, like a circle or red shadow or whatever. If you're spectator, they'd be completely invisible. They should also be noticable, but not very out standing, like the ugly reticules in BIA. If you disobey orders you'll get warnings, but I still don't know how to punish the player. Maybe too much insubordiation will result in a kick or death (death I'll talk about later).
If you're being supressed you could shout "TAKE COVER" over the VOIP or press the key which would make you're character shout "TAKE COVER" with subtitles in the squad meber's screen, like wise to command the squad as a whole to supress or to follow the squad leader. The Squad leader would also need to have some sort of distinction because squads could sometimes mingle and squad member's might get lost, the squad leader's name could be bolded or bright silver, or have an icon next to it. Maybe the squad member's could have a special icon signifying their squad which would also be displayed on their own screen so they won't forget. To keep this from being too much like from BIA, we'd keep out the supression indocators.
There would be respawns, but you'd have to wait, like you can't respawn individually, but you'd have to wait for all required classes for a squad to be complete to die. That way, when you die, you'd be for instance an MGer, but another MGer dies
and you'd both would have to wait. You'd be unassigned to any squad. Once a squad has been eliminated, one MGer can join it, or if two or more squads are available they could choose. You'd choose you're class before you're squad, and to eliminate the faster-load-time-better-class problem, you'd wait until everyone joined. So not everyone is going to want to take MGer, and if you do, there's problably two or three slots open anyway.
Vehicle support is also a problem. If the platoon leader wanted the tank over there, he'd have to press the key, indicate the place, the commander would tell his driver to drove there. Furthermore, it's hindered by porr sight. Pretty slow. My solution is that the driver, Hull gunner, commander and loader is played by one person, if you pressed forward, for the sake of realism, you're character would shout forward, only you could hear and then a split second lag, then it would move forward. Not to mention animations to climb in and out of tanks, and a key to cycle view, I.E. press [F] and you'd be looking through hull gunner position and only be able to fire the hull mg, but still if you pressed forward, your commander would still shout "FORWARD" and the driver would still drive, all being done by you, since of course we can multi-task.
Supression should knock off you're aim and give you some sort of pyschological scare, and death should also be a scary experience. I like the idea about VOIP channels specific to certain things.
But, unfortunately, this would result in a totally new game.
