Also, appoint the better thinking players as admirals(or at least hope a smart one gets control of the TG).
......
The main strength of TGs lie in the fact that they are mobile airfields. Able to change positions, sneak into range unnoticed, and attack targets which positions are already known, while its own position stays hidden.
Once an attack launches, and planes are caught on radar, it means the position of the TG can be guessed out and confirmed.
And a discovered TG, is a dead TG - unless constant air power defends it against all incursions, or at least, defends it so the interval of successful enemy attacks, are longer than repair time.
Even if gun positions and radar can be damaged, a TG is a pretty solid defense platform. If the enemies can get close enough to strafe guns dead, and the loss of those few guns are so severe an impact in the battle, then it means the commander of the TG made the wrong choice of putting the TG into unnecessary danger. It should have retreated a bit until CAPs reformed, and defenses were back up.
