You know, sync Ozzy up to Jack's hardware and she'd be able to paint targets for it right in the field. This is good, between a demolitions expert and a robotics expert I'm seeing a good couple of people that my character will work well with :D
That said, dang, 23 seems oddly young for a robotics expert. Does he perhaps have some sort of neural uplink that allows him to directly interface with computers to some extent, possibly to assist in learning by directly uploading sections of data to his mind or allowing him to input data faster than with analogue devices? Ignore me if this isn't the direction you were thinking of, I just enjoy brainstorming. And I mean Jack has some mind/machine interface hardware going on, so it apparently does exist in this setting. Actually, if such things were relatively commonplace, it would explain why non-combatant experts might be of a younger age, they would need less time to reach a similar level of competency when compared to organic learning.
