CHAPTER 6 (p. 152) New Directions All the services developed new racial policies in the immediate postwar period. Because these policies were responses to racial stresses peculiar to each service and were influenced by the varied experiences of each, they were, predictably, disparate in both substance and approach; because they were also reactions to a common set of pressures on the services they proved to be, perhaps not so predictably, quite similar in practical consequences. One pressure felt by all the services was the recently acquired knowledge that the nation's military manpower was not only variable but also limited in quantity. Military efficiency demanded, therefore, that the services not only make the most effective use of available manpower, but also improve its quality. Since Negroes, who made up approximately 10 percent of the population, formed a substantial part of the nation's manpower, they could no longer be considered primarily a source of unskilled labor. They too must be employed appropriately, and to this end a higher proportion of Negroes in the services must be qualified for specialized jobs. Continuing demands by civil rights groups added to the pressure on the services to employ Negroes according to their abilities. Arguing that Negroes had the right to enjoy the privileges and share the responsibilities of citizenship, civil rights spokesmen appeared determined to test the constitutionality of the services' wartime policies in the courts. Their demands placed the Truman administration on the defensive and served warning on the armed forces that never again could they look to the exclusion of black Americans as a long-term solution to their racial problems.
