Corps Headquarters

An Army controlled one or more (usually between two and seven) Corps. The Corps was a permanent headquarters which controlled as a rule from two to seven divisions. The division was the basic" self-contained" unit of the German Army and its structure varied according to its type. All headquarters were, however, organized according to a uniform system and consisted basically of a commanding officer assisted by a staff. The staffs of corps and higher headquarters were headed by a chief of staff. At all German headquarters, the staff officer in charge of operations was known as " la," the chief supply officer as " Ib," and the chief intelligence officer as " Ic."
