Armee-Abteilung Strantz / Armee-Abteilung C (Army Detachment C) was an army level command of the German Army in World War I. It served on the Western Front throughout its existence.

Armee-Abteilung C was formed on 18 September 1914 from the left (southern) wing of the 5th Army as Armee-Abteilung Strantz, named for the commander of V Corps. Strantz remained as commander of V Corps but was deputised in this post by a Divisional Commander. It was established on 2 February 1917 as Armee-Abteilung C. It was still in existence when the war ended,^[1] serving on the Western Front as part of Heeresgruppe Gallwitz.^[2]

The following Orders of Battle illustrate the growth of the Armee-Abteilung during the war.

By the end of the war, the majority of the units assigned were lower quality Landwehr divisions.

Armee-Abteilung C had the following commanders during its existence:^[5]

• Armee-Abteilung or Army Detachment in the sense of "something detached from an Army". It is not under the command of an Army so is in itself a small Army.^[7]
• Armee-Gruppe or Army Group in the sense of a group within an Army and under its command, generally formed as a temporary measure for a specific task.
• Heeresgruppe or Army Group in the sense of a number of armies under a single commander.
