[WIP] IRAI (Intelligent Random AI)

[Jaguar]

Not very clever behaviour from artic convoy escorts (42, feb/mar): against a convoy with usually 10-12 escorts (btw can this be adressed? it´s far from realistic) from a distance about 7-8 km, on surface, just fired torpedoes (very difficult shot) and go away at max speed. As soon as escorts detects torpedoes they went right after sub (probably because it makes a hell of noise at max), never caught me though. Latter I discovered that DDs chase me at 14 kts, my sub does 17...

It works every time, half of the totally unrealistic strong escort stay with the convoy (clever IRAI rule), half go after torpedoes source, but at 14kts they will get naught.

I think the correct speed would be more like max for a few kilometers or something alike.

I'll send you v0.0.32 as of now and you can test and see if the same thing happens

Report:

Used the same tactics already mentioned twice against the same artic convoy (May, 42), but this time with a diferent outcome. The escorts now go at flank speed (20-35kts) to where torpedoes were fired and bunch up there like flies in a manure pile. Still got out unscathed because, knowing something like that might occur, I fired from 9-10km and turned tail very fast.
But a much worst thing happened, as soon as the DDs became aware of the torpedoes the entire convoy changed speed! In both cases it went from 10kts to 5 kts. Dang! There goes my fire solution (in both cases automatic to ensure a hit).

Out of 10 torpedoes fired, 2 prematures detonations and just one hit. All in all: awesome .

Another nice feature is that sometimes a DD dettached itself and did a sweep near my shadowing sub.

TDW, two things for consideration:
1 - There was about 20+ DDs on this particular convoy, around 12 of them went to the exactly place torpedoes were fired and stayed around a tiny area. I guess, given the numbers, they could have searched a wider area.

2 - IMO there are a way too many escorts to each given convoy. I don´t know if it can be changed, but a more likely figure would be 6/10 escorts (DDs, DEs, sloops) and not as many as merchants. At least not in the close escort group.
(I´m going to look on this subject and report latter).


Tactics against this new evil IRAI (so far): fire FaT torpedoes to countermeasure the probable speed change and do it at night. You`ve got to get closer than with regular G7as, about 7-5 km, and must get out very fast (leave G7e in port). If DDs got near dive, change direction, go deep, slow down and pray. (EDIT: forgot to mention stoianm has a good tutorial about it, but he does it while submerged, not sure how it will work against this IRAI version though...).

Agree and I will reduce the numbers to almost half in the upcoming mod with the mines and stuff, depending on the convoy size. This is on my to do list.

Great news! If you need help defining those numbers just ask.

Any advice and suggestion is welcome.

GWX Team used historical Mine Deployment Maps by date and Convoy Configuration for SHIII. I think I have the Mine Maps somewhere.

May want to look in GWX to save some research time.

Good to know about the bunching up. I'll have them do spiral searches instead of bunching up like flies This way there's a better chance they'll detect you

TDW, Can you release your latest 0.0.32 as beta to test?

I will tomorrow. More work to be done on it still

Im done with placing the mines already, now I work only on placing the dolphins and the new ships in the campaign. GWX used also historical maps to set up the mine fields, I did the same. But if you have a mine map used in GWX, please share it, I wanna see if is any major difference from what I did. If you post a map, please do it in the WIP topic here, so we will keep this one clean.

Mein gott, I should be executed to help the enemy!

Nevertheless, glad to help.

Ok, will report in the WIP thread.
