A German infantry division during WWII had three main groupings within its larger structure, the divisional staff, the combat elements and the back-line services. The divisional staff of the division was a part of the headquarters unit of the division. The divisional commander was the leader of the entire division. As such, the commander was in charge of all operations and employments of the division. But in order to function in this position, a divisional commander also needed the help of a staff that would in turn be responsible for a number of different aspects of the division. This staff would help to run and manage the daily affairs of the unit, being responsible for areas like supplies, transport, air liason, and combat support, as well as many others. The staff of most combat divisions was organized into three operational groupings. These three groupings were known as the following.

二戰德軍步兵師是由三大部分所組成：師部參謀、戰鬥單位和後勤單位。師部參謀是師團司令部的組成單位之一，師長則是整個師的指揮官並且負責整個師的部署與行動，但是為了順利遂行而必須有一群參謀針對各專業領域來協助師長指揮。這群參謀協助執行管理師團內各單位的相關日常事務比如：補給、運輸、聯絡空中支援以及戰鬥支援等，參謀群並分成三個領域如下：
