Answer:
Executive Order 9981 was proclaimed on July 26, 1948 by President Truman. The purpose of this executive order was to end racial discrimination in the United States armed forces, in order to fully include members of the African American ethnic group within them.
As of the enactment of this decree, African-Americans were able to include themselves in the armed forces in the same units and under the same conditions as whites. Previously, their situation was different and inferior, both in terms of rank, salary and rights, and even in terms of specific military tasks and even preparation.
