Reminds me of how Scimitar when it was initially modelled had all the communications systems set up as optical and fire control, and the RARDEN linked to optics until it got proven to them no, thats a radio, no, rarden doesnt work that way.
So I do assume some of this is turret traverse stuff, but wouldnt be surprised if gaijin got a lil zealous.
In theory either of them could be damaged to the extent that they physically obstruct turret traverse, but that would only be after a catastrophic penetration of the hull so I think the crew would be focusing on something else.
