Yuki, and many of the other young Americans of Japanese Ancestry (AJA), want nothing more than to prove their patriotism by fighting for America, THEIR country.
This story is truly amazing. Reading about what these men endured, how they fought, where they fought, how they were used as assets in the European theater, and how they died was fascinating.
Yuki was fictionally deployed as part of the 100th/442nd Regimental Combat Team, a combat team that in real life was comprised of about 18,000 AJAs throughout the course of the war. They are still the most decorated unit in U.S. military history. Approximately 50% earned a Purple Heart and they suffered a staggering 314% casualty rate.
