Yup pay attention to the targets course and speed through the hydrophones. If you hear them alter course and suddenly jump to flank youve been 'spotted' time to get the hell outa there.
How long did it take you to get away?
Oh... by the way... If you really want to 'role play' the mission usually inserting agents took precident over tonnage on the way there. Of course after he is 'safely' inserted feel free to blast away
Of course the game doesent make this distinction but ... well orders are orders
Oh and welcome to subsim !
