Thanks LandMarine...
Great suggestions! Am collaborating with Amaris on new Guadalcanal/Eastern Solomons maps for NAM, while borrowing some of NAM's strategic concepts to use them with BA's 3D tactical engine (NAM is a huge trigger for my experimentation with destroyers, Vorpostenboote, DUKWs and Coastal Guns in Normandy Ninjas

). More info/screenshots here ->

Agreed that destroyer/Vorpostenboote bombard attacks are too effective. My rationale for the first cut was that RN destroyers should be more powerful than Tigers (in reality, S-class HMS Scorpion had 4x 120mm guns, Hunt-class Talybont and Tanatside had 4x 100mm guns, Vorpostenboote carried 88s, Tigers also carried 88s), so I set the APattack values with that in mind. The problem is that BA handles bombard attacks by defaulting to the APattack value in full, and that's too much for a bombard. However, I believe that I can dial that down by adding extra data to the squads.csv file, so expect that in the next update to GJS'44 and Ninjas. See discussion here ->

For now, my recommendation would be to remember that ships are BIG targets, which make them easy for 152mm coastal guns, 88s and even 75s to take a pop at, especially side on. Also, if you haven't tried it yet, they really don't like off map artillery drops. However, as you would expect, their AA defence is high.
St Nazaire & Dieppe. Operation Jubilee eh? Have you got any maps and photo recon of the battle areas? Plus some details on army/naval orders of battle and unit types for both sides? If you do, let's experiment. Sounds like a good one to add to the Normandy Ninjas package (if that's acceptable to you?

) Btw, did you know that the crossword clue "French port" appeared in the Daily Telegraph on August 17th, '42, with the solution "Dieppe" on the 18th, and the raid itself on the 19th...
