What were two things that African-Americans did to help the war effort?

Since this question doesn’t mention a specific war, I will use World War II as an example.

There were ways that African-Americans helped the United States in World War II. Some African-Americans served in the military. African-American units were segregated during World War II. However, these soldiers fought bravely. Some were recognized for their bravery and others made the ultimate sacrifice while fighting. African-American men and women both served during World War II.

African-Americans also contributed to the war effort at home. They filled some of the jobs that were available in factories that produced materials for the war. Some African-Americans relocated to do this. They supported the government initiatives to conserve food. They bought liberty bonds. They also emphasized that in their minds this war was being fought to fight racism at home and abroad. While African-Americans were fighting for freedom in other parts of the world, they still faced segregation and discrimination at home. The Double V Campaign addressed this issue.

African-Americans made many contributions during World War II.
