As I recall, there were quite a number of Asians in that war - maybe that would help.
Not that many Asians, unless you count allies.
The Japanese were in just one RCT (Regimental Combat Team), and the Filipinos had two (not counting the Scouts in the Islands), but they had to be reduced to one for lack of replacements. The US raised over 300 RCT’s. IIRC the Chinese were integrated but there werent many of them.
There were lots more “Hispanics”, and they were always in integrated units. Some National Guard units were very hispanic. The old folks in Manila say the 8th Cavalry (1st Cavalry Division) in 1945 mostly spoke Spanish, and they liked that. Then there was the New Mexico National Guard 200th Artillery (antiaircraft), which was captured at Bataan. Most of its men were New Mexico “Spanish”, or Indians. Etc.
There were also @50,000 Mexican volunteers that crossed the border to do so. IIRC they could just walk across and enlist. Most I think ended up in the infantry.
Now, Rhode Island would have had very few non-whites in the 1940s, and any black soldiers would have been segregated and very unlikely to be in combat units.
