All for specific platoon on/off switches.
As for removing a team, I don't think that's the best way to do it. If it's done at the wrong time, could lead to the team not being placed back in fast enough. I think the best way to do this would simply be allow players to edit their teams after they've been placed. That way a squad is always in place there and it solves all the wrong leader/mixed up a toon or something placements and the person who placed it would still have to place a squad, but would just be able to re-arrange who is in the squad based on what they have left.
