Basically the 3rd passenger in the tank can communicate with the squad while looking 360degrees on top of the tank with zoom and thermals(green)!
This mechanism is through a scope like device placed on the top of the tank, the passenger can use the compass to pin point targets for the gunner:
VOIP example:
"Enemy up on the hill, turn around hes at 256!!! 256!! hurry up!"
"Roger that, turning hold up"
"Another enemy behind the tree at 45, get the lalalala!!"

Remember the tank gameplay trailer? The tank has a big long compass on the top, the CITV has one too:
The likely outcome being the spotter has thermals exclusively and the gunner without, this will force teamwork among tank squads +1
Possible counter measures include:
- Infantry on the ground can LASE the tank as a target for a lock on missile from a JET or Heli, maybe even infantry eg. Javelin.
- The Spotter does not drive the Tank, gunner has full control.
- The Spotter position could be linked to a UAV to call in some A-10's like in the thunder run gameplay vid. Or could be used to call in a mortar strike.
This is not easy though because you have to use your binoculars to lase the tank, the spotter could see you:
The green square is visible to Jets and Heli's in a larger form, maybe even the javelin
