Answer:
Du Bois's comments on African American military service during World War I would apply to Black military service at any point in the Jim Crow era because of the pervasive racism and discrimination that existed in the United States military and society as a whole during that time. African American soldiers were often subjected to harsh segregation and unequal treatment, both on and off the battlefield. They were often denied access to basic facilities, such as barracks, mess halls, and hospitals, and were given inferior equipment and training. They were also frequently denied the opportunity to serve in combat roles, instead being relegated to menial labor or support positions. Despite these challenges, Black soldiers served with distinction and honor, fighting for their country even as they faced discrimination and prejudice at home. Du Bois recognized the sacrifices and contributions of Black soldiers, and his comments reflect the ongoing struggle for civil rights and equality that African Americans faced during the Jim Crow era.
