Their work made this book possible. The 2012 Damage Point Standard: This version of Gruppe Nord has been updated to use the “2012 Standard” to calculate a ship’s damage points. This method, described in the April 2012 issue of the Naval SITREP (hence the name) matches historical results more closely than the older “2006 Standard” used in earlier versions of this supplement. All of the ship damage points in this supplement have been changed. Other corrections and updates have been made through- out the booklet as well, including adding a new scenario. The updated .pdf of Gruppe Nord is available as a free download to earlier purchasers. If you have purchased the print-on-demand edition, you will have to either purchase a new copy, or make pen and ink changes using the Damage Point Summary, available as a free download from The Wargame Vault and our website. It lists the damage points for all the ships in the Admiralty Trilogy system, as well as background on how we calculate damage points, and the new formula. If you are using ship data from more than one Admiralty Trilogy publication, make sure that the damage points have all been calculated using the 2012 Standard. Annex Notes: The information on the platforms, weapons, and sensors in this annex has been standardized so that it is compatible and consistent with all Admiralty Trilogy games. Equipment that was used in more than one era will have the same statis- tics in all games. The Annex designations are standardized for all three Admiralty Trilogy games: Fear God & Dread Nought, Command at Sea, and Harpoon. Gaps in the sequence are caused by annexes that are not applicable to the era or the product. If there is information in another Trilogy publication that conflicts with the data printed in this publication, use the infor- mation in the product with the newest copyright date, since new information and corrections can change statistics. If you have a question about the conflict, or about any other data listed, please contact us. Except for Annex A, systems are listed in their Annexes alphabetically, first by country, then by name. The ships in An- Samplenex A are listed in traditional order, with capital ships first, followed by minor combatants, submarines,file mine warfare craft, auxiliaries, then civilian vessels. An alphabetical list of ships by class name is provided on the next page. Systems listed in italics never entered service. They existed only in prototype or developmental form.
