What is up with the gun chart?

[Bandit LOAF]

Also, the guide sugests that you use "by-the-book" torpedo runs against the Ralatha in Novaya Kiev D, and even states that it's no problem at all. As we all know, try this approach, and the AMG of that gunjockey of a destroyer captain will eat you alive!

The WC2 part of the book was actually written while the game was still in development - so it's a little less accurate (and detailed).
