There is another interesting point about this: If there is a difference between veterans and greens manning the sonar station, comes this difference from the overall compartment quality or ONLY from the guy at the hydros ?
I mean, in the case that it's the overall compartment quality that matters, you could place two half-way-experienced soldiers in there, one at the hydrophone station and the other at the radio station. Thus leading to a good value in compartment efficiency there.
But how should the radio man be able to help the sonar man recognizing contacts ?
