I am sure that more experienced divers could write a book on this topic and the above is a mere flavour.

However I want to add a rider to my remark about ''extreme caution'' Within this 'game' fortune favours the bold.
There is always a trade-off between the risk of exposure and deploying your sub and its sensors to
maximum advantage. The need to obtain and implement the most accurate sensor information is paramount to
securing the 'big picture' and initiating an attack.

Aggressive, and successful, submariners will always risk exposure to secure the initiative.
