4. As said already, make sure your target is more than 300m away. If it's moving towards you, the range will be shorter so you may need ~500m. I find the ideal range is between 500-1500m.
Also, if you're using Impact torps, try to get them on a 90deg angle and they wont bounce off. If your using mag torps the goal is to get them 1m under the keel, and any angle will do.
5. I give promotions to people who do the most work. eg, A sailor who has been in his quarters the whole patrol proberly wont be promoted. But someone who is doing a job I will promote.
