WWl
More than 350,000 African Americans served in segregated units during World War I, mostly as support troops. Several units saw action alongside French soldiers fighting against the Germans, and 171 African Americans were awarded the French Legion of Honor.
WWII
Despite a high enlistment rate in the U.S. Army, African Americans were not treated equally. At parades, church services, in transportation and canteens the races were kept separate. A quota of only 48 nurses was set for African-American women, and the women were segregated from white nurses and white soldiers for much of the war. Eventually more black nurses enlisted. They were assigned to care for black soldiers. Black nurses were integrated into everyday life with their white colleagues. The first African-American woman sworn into the Navy Nurse Corps was Phyllis Mae Dailey, a Columbia University student from New York. She was the first of only four African-American women to serve as a Navy nurse during World War II.
Answer:
Because of the Alliance with Serbia, France and Britain, and fear of German expected demands
Explanation:
The reason the Russian provisional government keeps Russian troops involved in World War I after the Russian revolution of 1917 is because of the "of the Alliance with Serbia, France, and Britain."
During this period, Russia still relies heavily on the loans they are getting from Britain and France, and at the same time, they also want to maintain the alliance with Serbia.
The Russian government also feared the kind of demands the German will ask of them if the Germans win the war.
