I have been following the tips. I have been reading the manuals and started playing sub command to get myself ready for dw. Having a great time with sub command. The ice maze mission was fun. Hit my first torpedo target last night. Need some practice on tma. Fired one fish and sank it, but my range was too long by about 100 meters. Dunno how I hit, but it did and I was pleased. Thanks for getting me started. Now I have something other than WWII subs to drive.
