SOS Need help with a few questions

[Werewolf]

Okay, I bought DW some days ago, but it isn't really what I expected, then I came across a DL link for SCU/SCX so my questions are:

Is it possible to play a campaign from a non US side commanding a modern diesel electric sub with the help of this SCU/SCX feature?

If yes where the heck can I buy sub command then!? I've been searching and searching but all links are dead.....I would prefere to purchase a download so I could get it straight away since I live in a dull little stinky European country where submarine sims is something you only read about

Any help would be appreciated
