Truman Gibson was quick to point out how segregation had intensified the problem of turning civilians into soldiers and groups into units. The "dissimilarity in the learning profiles" between black and white soldiers as reflected in their AGCT scores was, he explained to McCloy, primarily a result of inferior black schooling, yet its practical effect on the Army was to burden it with several large units of inferior combat ability (_Table 2_). In addition to the fact that large black units had a preponderance of slow learners, Gibson emphasized that nearly all black soldiers were trained near "exceedingly hostile" communities. This hostile atmosphere, he believed, had played a decisive role in their adjustment to Army life and adversely affected individual motivation. Gibson also charged the Army with promoting some black officers who lacked leadership qualifications and whose performance, consequently, was under par. He recommended a single measure of performance for officers and a single system for promotion, even if this system reduced promotions for black officers. Promotions on any basis other than merit, he concluded, deprived the Army of the best leadership and inflicted weak commanders on black units.

Gibson was not trying to magnify the efficiency of segregated (p. 138) units. He made a special effort to compare the performance of the 92d Division with that of the integrated black platoons in Germany because such a comparison would demonstrate, he believed, that the Army's segregation policy was in need of critical reexamination. He cited "many officers" who believed that the problems connected with large segregated combat units justified their abolition in favor of the integration of black platoons into larger white units. Although such unit integration would not abolish segregation completely, Gibson concluded, it would permit the Army to use men and small units on the basis of ability alone.[5-42] [Footnote 5-42: Memo, Gibson for ASW, 23 Apr 45, sub: Report of Visit to MTO and ETO, ASW 291.2 (NT); see also Interv, Bell I.
