How did president truman's executive order 9981 show progress toward racial equality?
the order ended segregation in the military.
the order set up integrated military housing for soldiers.
the order dismantled the internment camps for japanese americans.
the order gave medals of honor to injured servicemen of different backgrounds.

The answer is "The order ended segregation in the military."

Step-by-step explanation:

President Harry S. Truman is the 33rd president of the United States of America. He assumed the President's role after the death of Franklin D. Roosevelt (the 32nd president of the USA). Under his leadership, he was able to abolish the issues concerning the discrimination according to race or religion in the USA's military force. This was backed by the "Executive Order 9981," which he issued in 1948.

The "Executive Order 9981" ended the segregation in the military. Before it was issued, the Black Americans were trained differently from the White Americans. The White Americans were given more priority than the Black ones. This means that the Black Americans have to wait and train longer before they became qualified. Later, it was found out that there was actually no sense in segregating both Americans, since they both performed well in the wartime.

Thus, this explains the answer.
