If Ive got time to avoid them then usually I'll just dive and keep an eye on it with the hydraphone and scope checks , But if it starts to take too much intrest in me or I get jumped by one the lookouts didnt see till to late then I get aggresive, im averaging 1 destroyer a cruise so far
, my best was a V&W that i killed in a surface gun battle 3-4 days ago - I hit it with a torp and it turned and ran , so i surfaced and chased it (I have no idea why i did that) , got the deckgun to aim at weapons and killed all its guns , finished it off with waterline shots into its stern
, sametime i was hitting the destroyer an armed trawler came running to its aid so i shot it up with the deckgun and AA gun as well
