CHS, The AI, V1.5, Problems and a few Answers

[Don Bowen]

I've spent a pleasant evening running CHS and Scenario 15 and comparing the differences. Two things are very obvious:
[ol]
[*] The AI is bothered by the reductions in transport /cargo ship capacity
[*] The move of the 18th Division results in it not being used
[/ol]

I ran both scenarios for several days (until December 12th). Japanese AI and human allied but made no moves for allied (auto sub was on so subs and autos have moved). Then saved game, reset Head to Head, loaded save game and let run until Japanese turn (December 13th positions).

Scenario 15:
Taken: Vigan, Aparri, Laoag, Legaspi, Kota Bharu
Under Attack: Davao, Kuching, Alor Star

Unit Locations:

• 5th Division – Alor Star minus 3741 load points at Taan and 244 at Singora
• 16th Division – on transports enroute Naga
• 18th Division – Near Kuantan minus 2005 load point at Taan
• 48th Division – Laoag
• 55th Division – Siem Reap!
• Imperial Guards – Siem Reap!
• 56th Brigade – Davao
• 65th Brigade – Near Laoag

Ships Sunk – 4 allied, 3 DD at Hong Kong and a Minesweeper at Guam



CHS
Taken: Vigan, Aparri, Legaspi, Alor Star
Under Attack: Georgetown
Note: No landings at Kota Bharu on first day. Task force loaded only supplies, went to Kota Bharu and then turned back. 18th Division, wherefore art thou?

Unit Locations:

• 5th Division – Georgetown minus 9131 load points at Taan and 898 at Singora
• 16th Division – Amani
• 18th Division – Canton
• 48th Division – Aparri minus 17705 load points at Pescadores
• 55th Division – Hex 29,38 approaching Tavoy
• Imperial Guards – Hex 26,40 approaching Victoria Point
• 56th Brigade – Palau
• 65th Brigade – Vigan minus 8290 load points at Pescadores

Note that the 16th and 18th Divisions and the 56th Brigade have not moved. In last night’s test (to May 2, 1942) they still had not moved.

Ships Sunk – 4 allied, Wake, Ariadne Moller, the two at Guam


Conclusions so far:
[ol]
[*] We need to add more transports to pre-formed transport TFs to make up for reduced capacity.
[*] Moving the 18th Division may not work as the AI is not able to adjust.
[*] There is a surprising difference in the use of the 55th and Imperial Guards Divisions. Used aggressively in CHS and not yet used in Scenario 15 (more testing required).
[*] Once the AI gets thrown off track it seems to lose it’s way. In the May, 42 test Davao and Kuching were never attacked.
[*] NO BATTLESHIPS have been sunk at Pearl Harbor in any of the V1.5 test (CHS or Scenario 15).
[/ol]

I’m going to move the 18th Division back to Taan, beef up the pre-formed Task Forces, and run CHS overnight, AI-AI. More later…

Moving the 18th Division may not work as the AI is not able to adjust.

I'm building a custom scenario, and have created several Japanese TF's with troops to invade Attu, Kiska, and Midway on day one (the only way to get the AI to do something little bit different. You will have to manually create the TF at the new location of the 18th Division, and load it on the TF.

Don Im seeing none of these problems in my AI test run of the new CHS scenario. The AI is advancing well and the 18th Division is in Meiktila:

In my test of Pry's Scenario 34....as of 3/26/42 18th Division is also in Meiktila
