15, RFB, RSRD
as far as the traffic goes: my third patrol (february 1942) I encountered only 1 ship. dutch merchant in the java sea. I actually liked it, completed 4 assignments and still got over 1500 renown at the end, in spite of not firing a single shot.
on the next patrol, being assigned a hotspot east off borneo i can't complete even the first day of my 72 hour patrol assignment without spending all torpedoes. 8.000 tonners just fly into my mouth. Weeks and weeks of absolutely nothing followed by a single day of continuous contacts. pretty much exactly how it was back then, i reckon.
Don't rely on your sensors, they are crappy especially early in the war. green crew etc, i guess. I never made it past 1942 because i always start in december 1941 and walk away from the bugs after a couple of patrols. But doing a manual hydrophone check every couple hours will reveal screws long before your sonarguy ever picks them up, if he picks them up at all.
as for the harbor raid. TMO and they did nothing? weird, i dropped TMO from my setup because the anchored transports keep avoiding my eels by going from 0 to 60 in 5 seconds upon spotting my torpedo wake in a pitchblack night. Perhaps ships in port are scripted entirely differently from ships which sail around and then anchor in some bay. (active status somewhere hidden inside the system or somesuch, i dunno)
Last time I raided a harbor in TMO the merchants didnt move but the patrolling guard dogs did switch on their lights and went after me.
oh and welcome
