One thing to keep in mind is there is no one answer. Tactics can depend on local weather, depth, number of ships in area, type of sensor, land proximity, etc. You have to have a plan A, plan B, and plan C. All the above parameters can change with one lost helicopter, travel, and other random events. I have always found a layered defense works best, but each layer is going to have to adjust to the above.
You are like puss filled boil on nice of ass of bikini model. You are nasty to everybody but then try to sweeten things up with a nice post somewhere else. That's nice but you're still a boil on a beautiful thing! - BDukes
