Optical relay for bradley

[leonpoi]

I think this has been touched on in another thread (somewhere), but I was wondering what the optical relay in the bradley actually allows. I understand it allows the commander to see what the gunner is aiming at, but can the commander control and fire the gun if the gunner is killed (or does he just shift over a seat?).?

I'm interested because I was reading the M1A1 article in the challenger mag and it says that the commander can take over the firing of the gun if the gunner is not available, and based on this picture, the commander must do this without physically moving to the gunner's seat.



I'm trying to find this type of info out for a variety (all) vehicles in the game so that I can understand what can be achieved if a vehicle is down a crew member or 2.
