During WW II the Command and General Staff Colleges primary mission was to train large numbers of captains and majors to be staff officers in battalions, brigades, divisions, and corps. To that end, the Army provided copies of documents produced by field units to the College. Operations orders, after action reports, intelligence analyses, logistics appraisals, and similar documents are in the Combined Arms Research Library documents collection. The primary focus was documenting operations at the tactical and operational levels of warfare. This document, administrative order number 1, covers the logistics and supply responsibilities for IX Corps for Operation Olympic, the invasion of Japan.
