Modding into Campaign?

[Krauter]

Hey all, I've been fooling around with different playable subs, most notably the Foxtrot/November mod, the Ohio and Seawolf Mods and the Typhoon and RedOctober Mods

All of these are for 1.4 of course.

My three questions are..

Out of the SH4 Mods section, there is a list of playable submarines, which are for 1.4 and which are for 1.5

Secondly, I've tried using the Typhoon in Campaign however it is unable to let me do this, only in single mission or war patrol.. how do I manage to Change the files to let me play in Campaign?

Finally, what are the surface mods that are compatible with 1.4?

Cheers,
