Personally, I dont find the 44/45 Kit set or the Battles from that Time frame all that interesting as they were very lopsided and basically just set piece meat grinders for fortified Islands, The US typically suffered over 100% attrition rates for it’s tanks but this largely do to AT gun’s firing at point blank ranges Mines and other close quarters killers, not Japanese tanks that were totally outclassed late war.
My Fondness for Burma, the Japanese Invasion of (42) is largely the Very varied nature of the Allied army there and the Nature of eh fighting there and the terrain, it’s not all jungle, there are urban areas, and rice paddies, and farmland rivers and Roads RR exc.
The Malay peninsula would offer some similar map options as would the Philippines, or Dutch East Indies, but they have fewer Allied forces.
Although in the Dutch East Indies, Java, you would find Australians and Dutch, and there were some American Aircraft there as well, along with British and of course Dutch forces.
But again Burma has:
British/Commonwealth, Chinese, and American forces.
The Japanese have a large assortment of kit that could be included, and again I do feal there armor is far more competitive early war and varied as a result.
Type 97 Te-Ke tankette 37 mm
Type 95 Ha-Go 37 mm
Type 98 light tank 37 mm
Type 97 Chi-Ha 57 low velocity, later 47 mm High Velocity gun
Bearing in Mind that Early War Allied tanks were for the most part poorly protected these tanks could be again, very competitive.
The Japanese also had a very wide array of infantry weapons to chose from.
