What was the purpose of Executive Order 9981 signed by President Harry S. Truman?

Executive Order 9981, signed by President Harry S. Truman in 1948, aimed directly at ending segregation and discrimination within the United States armed forces. The order mandated that all branches of the military provide equal treatment and opportunities for all service members, regardless of race, color, religion, or national origin. This was a significant step towards racial equality in the military, setting the foundation for further civil rights advancements in later decades. The integration of the armed forces was part of a broader movement to challenge and dismantle systemic racism in various sectors of American society.

The other options do not align with the primary intent of the executive order, which was focused on military integration and civil rights, rather than immigration or economic opportunities.
