I could imagine subs hunting other subs using WW2 sonar,
firing torpedoes when they have a firing solution, pt boats hunting subs and dropping depth chargers...
........ subs coming to the surface to machine gun the pt boats..........I can imagine allot with subs in AH.

.
Planes coming off the CV to search for subs........subs sinking CV's..........there would be another battle in AH. Das Boat. AH is better than the other online battle games because there is so much to do in one arena.
A sub surfaces at just the right time to kill all the LVT's. I can think of allot of scenarios. A sub could compliment a CV group and help protect from other subs.
Spawn points in key areas of the map and a spawn for the CV as well.
I would name my boat "The USS Rustoleum"
"Take errr down, up periscope"..........."ARRrrrrrrrrrrrrrrr matey..........."
