Dear Crazy Ivan,
I had a thought a while ago- I saw a documentary on the Trafalgar subs - and they place a machine-gun on the sail for transits through hostile straits that are too shallow to be dived.
I was wondering, is it possible to add to or replace the sub SAM with the machine gun from the Perry-Class Frigate gun station?
It'd be cool to fight off suicide attacks while exiting harbour!
Anyways, just an idea I had - keep up the cool mod, Sir!
