  • Chemical, biological, and radiological warfare equipment

  • Construction equipment

When this booklet was published, the technical intelligence in the US Army was about eight years old, and technical intelligence requirements had matured. However, this appears to be an inadequate attempt to give guidance to Army forces in the field.

At that time, technical intelligence was divided among a number of organizations in the Headquarters, Department of the Army. The Office of the Assistant Chief of Staff for Intelligence (OACSI) was the General Staff agency in charge of all national-level intelligence related to ground forces. A staff section in the OACSI coordinated the technical intelligence efforts of the army.

The Army Technical Services produced technical intelligence. The technical services were bureaus which supplied weapons, equipment, and services to the Army, managed the careers of officers in the various branches, trained specialists, and organized and trained special purpose military units. There were a number of technical services including the Chemical Corps, the Corps of Engineers, the Army Medical Service, the Ordnance Corps, the Quartermaster Corps, etc. The Quartermaster Corps, for example, developed, procured, and issued clothing and equipment and supplies for the Army; operated the Army burial services; managed the careers of officers commissioned in the Quartermaster Corps; organized and trained specialized quartermaster units for the army; and ran Quartermaster schools.

The headquarters of each technical service was the office of the chief of the service in Washington. For example, the Quartermaster General was the chief of the Quartermaster Corps. The Office of the Quartermaster General was his headquarters and a part of the Headquarters, Department of the Army. Most technical intelligence was produced by staff sections within the offices of the chiefs of the services.
