What American ethnic groups took part in the military effort during World War II?
All American ethnic groups took part in the military effort during WWII. Some of them were not allowed to take as great a part as others (there were segregated units and most blacks weren't put in combat positions, for example), but all of them took part.
As a few examples, we have
- Asians. The Japanese-Americans took part in the war, though they were only allowed to fight in Europe. The 442nd Regimental Combat Team is the most famous example.
- Native Americans. The Navajo "Code Talkers" are the most famous example of this.
- Hispanics. They were not segregated in their own units like blacks and the Japanese-Americans, but many served. 12 Hispanics won the Medal of Honor in the war.
