The author perennially prepares slender volumes such as this one on American manpower policy. Bedecked with statistics and graphs, they do not make for light reading, but their combination of thoroughness and dispassionate analysis provide an essential grounding for those interested in current manpower issues. This book has even more to offer, because it deals admirably with two sensitive issues: the introduction of women into combat roles and the role of black Americans in the military. The import of the evidence he adduces on the former issue in particular may displease those who eagerly anticipate the day when women can volunteer for the infantry. A good place to look for a fair and balanced treatment of some difficult issues.
