Hello!
1)I have my WO identify ships,although by now i know the shillhouettes by heart.But i don't want to lose time opening that book.I 'd say that at medium fog you should be able to measure the range.In heavy fog it's too difficult to do so especially more than 300m away that is the safe range for the torpedo to arm.This said,i play the stock game with mods.I thinj i have read that the RUB mod makes everything darker to look more realistic,so there you have it!I am too old to strain my eyes,so i use the normal game luminosity
2)You may look for such a mod in the workshop.
3)oh,attack them day or night,it doesn't matter.In reality,they used to attack night on surface.In the game if you close to firing range at night,they ll spot you and fire at you,so don't worry about being realistic,because the game itself isn't here.Attack by day.I see better then too
4)You ask too much.As most things in that boat,if you want something done well,you have to do it yourself.I can't make my sonarman report correctly the position of the attacking DD and you ask a report on certain ship?:rotfl: The other day a DD was making its run at 270 deg on me,my sonarman lost him...We found him again when we took a shake from the depth charges
