The members of the committee met periodically with CWS scientists and administrators to discuss policies and problems of research and development. The CWS Technical Committee, also set up in 1920, came into existence as the result of a need for co-ordination among interested branches of the armed forces in the development and standardization of chemical warfare items.On the Technical Committee sat representatives of CWS and of the following Field Artillery, Coast Artillery, Infantry, Air Corps, Cavalry, General Staff, National Guard Bureau, and the Assistant Secretaries of the War and Navy Departments.
