Thanks for replying,
Guess there's obviously no way to tell which crews are elite and which ones aren't? Does the same apply with escorts?
Have you or anyone else got ahead of a convoy, gone as deep as possible, waited for the escorts to pass you and then go to periscope depth in the middle of the convoy and lay waste? If that were to happen, then chances are the convoy would pass you by before you could even get to pd right? Haven't tried it that way before either but is it something worth trying?
Also, when attacking at night, is it advisable to get close in on the surface before going under and attacking? Or can you execute a whole attack on the surface if conditions permit it? On average, how close can you get on the surface before the escorts spot you?
Sorry with all the questions, since the game is nice and challenging, I'd like to be best prepared.
