For those of you who are interested in the "Detached Enlisted Men's List":I wrote to NARA to ask about its definition.They did not cite the specific reference but sent the following:
"The preceding table[which they did not include] 'Detached Enlisted Men's List' generally consists of trained soldiers of several years service and are organized into a detachment similar to a company and in most instances stationed at an army post.They require very little military instruction other than routine inspection and disciplinary supervision. They are principally on such duties as clerks, chauffeurs, orderlies, stablemen, and mess and supply.While in some cases their duties could be performed by civilians, such action is not considered to the best interest of the service.Corps Area Headquarters are closely in contact with troops, and the personnel on duty thereat, in emergencies, both civil and military, is subject to duty 24 hours a day.In addition, under our mobilizatin set-up, an Army Corps Headquarters is to be organized and take the field from Corps Area Headquarters.The enlisted men now serving at Corps Area Headquarters will provide a cadre of trained personnel for the field organization, which will be invaluable in such an emergency. Returns Section, Miscellaneous Division, A.G.O."
