Maybe this is more a topic for mission editor, but as it maybe involve tactics I will put it here.
Admins, feel free to change it.
Trying some tests myself sneaking with my sub behind a ship (not cavitating, at speeds about 8 to 15 knots) with a counter-detected trigger, I saw that the counter-detection range for the AI is more or less the same with or without ship. Am I right or am I doing something wrong?
Searching in the forum (there are really great discussions, is always interesting dig in the threads) I found that the AI detects you, but can't classify you as a submarine in the mix of frequencies.
Well, this is good, but doesn't serve to make missions...
If I want to make a mission about crossing a strait and one possible choice is to hide behind a ship, is no important whether you are detected or not by an "enemy" sub, but not being ID as a sub. How could this be done if it can be?
