By analogy, since turrets are often remotely operated, I'd go with the Heavy Weapons skill.
The task chain might be more appropriate for, for instance, the driver, though.
But that's interpretation, the example in the core book pretty clearly points to use of Remote Ops for "control" which seems like it would be for driving or "remote hands".
But the more I think about it, the more I like your task chain for all of it.
