Progress.
I found a combination of waypoint assignments and animations to get everyone using their binoculars in generally the right direction. It offset the port watch a bit differently then before, opening up the area left of the UZO for the player a bit more. The down side is the aft guy has his foot partially in the periscope housing. Another trade off.
I have the dive/surface commands mostly done, so the Chief will call out hydroplane and ballast orders corresponding to the command.
