I get that, but still...
Tried out the 84 campaign again, today...orders on a surface convoy. Okay, keeping in mind your pointers on the map - got myself in position in front of them, no overflights, slow maneuvering and then stopping...annnnnd...CONTACT! Great!
Mission starts and...I've actually got range on the target! Fantastic! IMMEDIATELY drop to 1 knot to improve solution and reduce detection, pick the closest (looking) contact, it's a Udaloy, and...oh, 10 seconds in and he's already got me at 15 signal strength on his active sonar and....yyyyeah, there's the missile coming at me.
(To be fair, your tip on positioning on the strategic map did help - at least I was able to get a decent long range on the convoy, and even classify the closest contact before it was able to get the missile off, so...a solid 5 seconds more reaction time than I was getting before, but I mean...)
