Thanks from me too Sid.

Very informative website.
I also found this interesting tidbit incase someone missed it...... Submarines sank submarines in WWII.......

Now we need AI subs to sink in SH5. Maybe as 'merchants' and countable towards the tonnage goals of each campaign section. If you could 'lock; on to a periscope in SH5, I bet you could sink one that's submerged. Surfaced should be a sub 'lock' on and in the recognition manual. Extra brownie points too for sinking a US or Brit sub.
