All right, thanks Hitman uploaded Fletcher's realism mods version 1.0 for Destroyer Command and Silent Hunter 2 version 1.6 You need them both patched up to the last patch (1.01 for SH2 and 1.1 for DC IIRC) as well as the PM patch 1.03 for both. Highly recommended both of them. Check the readmes of course for correct patching order with the other mods that were around at the time.
