It would be pretty cool if SH4 had a claims system where you actually had to claim ships as sunk or damaged. No more "Enemy unit destroyed"-messages and log entries confirming sinkings. If you're in visual range with the scope up when the target goes down, your claim will be viewed favorably by the higher ups. If your sonarman reports breaking up noices, but no visual confirmation can be acquired, high command might not be so easily persuaded. Add distress signals from sinking Japanese ships to the equation and you might even get confirmation from Ultra on slow sinkers that requested assistance before they foundered and it would be a nice little system. Then JANAC gets in on the act cutting your tonnage in the post-war analasys and we might even get as frustrated as some real life skippers.
