Question

which represents a major effect of changing us military policy on african americans in the korean war?
an executive order ending segregation in the military meant that hundreds of thousands of african americans served in the war.
the promise of full voting rights to anyone who served led thousands of african americans to enlist in the armed forces.
the rescinding of the gi bill led to a major decline in the enlistment of african americans in the armed forces.
a law requiring that all military personnel obtain college degrees meant that more african americans could not serve in the military.

Explanation:

Executive Order 9981, issued by President Harry S. Truman in 1948, ended segregation in the U.S. military. This led to a significant increase in African - American military service, including during the Korean War. There was no promise of full voting rights specifically tied to military service in this context. The G.I. Bill was not rescinded, and there was no law requiring all military personnel to have college degrees.

Answer:

An executive order ending segregation in the military meant that hundreds of thousands of African Americans served in the war.
