More than likely, but there was at least one other unit with Americans of Japanese ancestry in WWII, the 442 was the most famous however, they proved their worth, and were one of the most decorated units in the War. Hurray for him regardless of which unit he served in. Still standing up for his rights not to be intimidated! More Americans with that kind of courage are needed!
He was in the 442nd. You the man, Art!
