The Army Ground Forces headquarters concurred generally with the Gillem Board's conclusions and recommendations but suggested the Army not act alone. The headquarters recommended a policy be formulated for the entire military establishment; only then should individual elements of the armed forces come forward with their own policies. The idea that Negroes should serve in numbers proportionate to their percentage of the population and bear their share of battle losses "may be desirable but is impracticable and should be abandoned in the interest of a logical solution."[6-17] Since the abilities of Negroes were limited, the report concluded, their duties should be restricted. [Footnote 6-17: Memo, Lt Col S. R. Knight (for CG, AGF) for CofS, 18 Dec 45, sub: Army Ground Forces Comments and Recommendations on Report of the War Department Special Board (Gillem) on Negro Manpower, dated 17 Nov 45, GNGPS 370.01 (18 Dec 45); AGF Study, "Participation of Negro Troops in the Postwar Military Establishment," 28 Nov 45, forwarded to CofS, ATTN: Dir, WD Special Planning Div, GNDCG 370.01 (28 Nov 45).] The commanding general of the Army Service Forces claimed the Gillem Board Report was advocating substantially the same policy his organization had followed during the war. The Army Service Forces had successfully used an even larger percentage of Negroes than the Gillem Board contemplated. Concurring generally with the board's recommendations, he cautioned that the War Department should not dictate the use of Negroes in the field; to do so would be a serious infringement of command prerogatives that left each commander free to select and assign his men. As for the experimental groupings of black and white units, the general believed that such mixtures were appropriate for combat units but not for the separate small units common to the Army Service Forces. Separate, homogeneous companies or battalions formed during the war worked well, and experience proved mixed units impractical below group and regimental echelons. The Service Forces commander called integration infeasible "for (p. 161) the present and foreseeable future." It was unlawful in many areas, he pointed out, and not common practice elsewhere, and requiring soldiers to follow a different social pattern would damage morale and defeat the Army's effort to increase the opportunities and effectiveness of black soldiers. He did not try to justify his contention, but his meaning was clear. It would be a mistake for the Army to attempt to lead the nation in such reforms, especially while reorganization, unification, and universal military training were being considered.[6-18]
