Do you use a deck gun?

[GreyFox]

I like the deck gun and have become fairly decent with it in vanilla SH3 (don't use mods yet). I took on a convoy and sank 2 destroyers, an armed trawler, a T2 tanker and a C3 cargo with it a couple of weeks ago when my cousin asked me to see if I could do it in late 1940. I lost 2 officers and 5 men, but I managed to do it. Of course I didn't save it though.
