How many black marines were there in 1963?

In 1963, the number of Black Marines in the United States Marine Corps was relatively small due to segregation policies and racial discrimination that had limited their recruitment and opportunities within the military. Although the exact number can vary based on different sources, it is estimated that there were approximately 5,000 Black Marines serving at that time. The Civil Rights Movement was gaining momentum, which eventually led to changes in policies and increased integration within the Marine Corps.
