What is "retreat decision chance" is, exactly? A simple modifier for AI to withdraw entire fleet when faced with a "stronger" enemy? Or does it (also) affect individual ship decisions to be somewhere else?

I think it is individual ship chance to retreat. Retreat too late is disaster for the ship. The tech is one of the most important for naval country big or small. But the trait is questionable because I don't have more info anywhere.
 
What's the trigger for the Soviet Union to declare war on Poland by itself? Can it, as Germany, be stopped (like with MR-pact)? I noticed that delaying Danzig or war will lead to a Soviet assault of Poland in 1940 if Finland had capitulated.
There is a late Soviet focus tree. 1940 looks quite early, look like the game go to unhistorical setting.

COMBAT_RETREAT_DECISION_CHANCE (22% per hour) affects both
  • individual damaged ships that fall below the HP threshold
  • as well as the entire task force when the strength comparison falls below the aggression threshold
The modifiers "Retreat Decision Chance", "Retreat Speed after initial stage", and "Enemy retreat chance" only affect the case of individual ships* modify this chance multiplicatively.

* this has been fixed in newer patches

I know this is a little unbelievable, but I came here to ask what effect the admiral personality traits, "Retreat Decision Chance" and "Enemy Retreat Decision Chance" have. Amazing timing as I see talk about retreat chance was already in progress. I saw on the defines that there seems to be a default chance of 0.22, but Bitmod's post let me know it is an hourly chance and it effects individual ships and the task forces and reminded me what the retreat decision was based on HP threshold and taskforce strength comparison.

Do the admiral personality traits work and are they additive, like the tooltip seems to imply?

It's just that based on this (as far as I understand it, at least) pretty much every ship will sit in battle deorged with large portion of HP remaining - not necessarily what you want them to do.

Thank you. And actual HP threshold for individual ships is defined by these:
REPAIR_AND_RETURN_PRIO_LOW_COMBAT = 0.6, -- % of total Strength. When below, navy will go to home base to repair (in combat). REPAIR_AND_RETURN_PRIO_MEDIUM_COMBAT = 0.3, -- % of total Strength. When below, navy will go to home base to repair (in combat). REPAIR_AND_RETURN_PRIO_HIGH_COMBAT = 0.1, -- % of total Strength. When below, navy will go to home base to repair (in combat). I suppose? Or is this only for the entire fleet?
(also, seems reversed for combat)

For the fleet as a whole, lacking XPHP should factor into the force comparison. For the individual ships you are right on the money with those defines. The numbers seem reversed because they are not actually based on the repair setting but the aggression setting. I.e. lower aggression settings set a higher HP threshold.

In case anyone was wondering, getting the communist civil war as GB results in the revolters keeping your puppets and faction membership, so don't be in a faction or have puppets if you're aiming for communist imperial federation.
 
Could you give an example?
Sorry for the delay! I originally asked, "Do the admiral personality traits work and are they additive, like the tooltip seems to imply?" I probably should not have said it implies it.

For example, does the Retreat Decision Chance of +25% under the Craven trait add another 0.25 to the default 0.22 chance of retreat for a total of 0.47 chance per hour?

The modifier used to be subtractive* with the base chance but got changed to be multiplicative somewhere between 1.10.5 and 1.11.12. The Craven trait on admirals does work, currently changing the probability to 22% * 1.25 = 27.5%.

*yes, if you test "Craven" admirals in older patches, their damaged ships never retreated, bottoming out at 0.1% retreat chance

Is there an easy way to spot which hull type a ship is made of in the ship designer? I find it cumbersome to get a clear overview of some navies, especially when revisiting old models that are already built in 1936. I've also had similar problems in the fleet view when trying to figure out the foundations for refitted carriers in the Japanese navy. I figure I must have missed some obvious information somewhere.

In the upper section of the designer, you can see the hull types. If you click on one, only the ship classes of the type will be shown.

To see all of them within the type, you may make sure to set a mark on "show outdated".

To get an overview of all ship classes again - and find the convoys which otherwise would not be shown at all - deselect the chosen hull type again.

If you instead wish to see the type of an existing ship, hover over the the ship in a task force to see the name of the class (which often cannot be seen in all it's glory at first glance).

You can also click on a specific ship within a task force (click on the symbol to the left - which also has an typical naval abbreviation like CL for "cruiser light").

I hope i understood your question correctly and could be of help. Sadly the user interface and controls could be a big tad more user friendly. :rolleyes:

...Are you telling me the Smoke Screen Specialist trait used to make your ships not retreat?

And Gentlemanly admirals seldom let _enemy_ ships retreat?

That is hilarious, in a sad way.
