I need sources for a class project. My group is doing a presentation on the Japanese American forces during WW2.

I know the internet doesn't list everything so if you guys can help, that'd be great.

The info we found covers the 442nd regimental combat team and 100th inf battalion.

We also found hinting at the 522nd field artillery, but cannot find much beyond the fact that they existed and they were a plug to fill holes in the lines
