Structure on formation
On formation in December 1914, XXXXI Reserve Corps consisted of two divisions.[5] but was weaker than an Active Corps
the divisions were organised as triangular rather than square divisions with three infantry regiments rather than four, but had a brigade of two field artillery regiments
Reserve Infantry Regiments consisted of three battalions but lacked a machine gun company[6]
Reserve Cavalry Detachments were much smaller than the Reserve Cavalry Regiments formed on mobilisation[7]
Reserve Field Artillery Regiments consisted of two abteilungen (1 gun and 1 howitzer) of three batteries each, but each battery had just 4 guns (rather than 6 of the Active and the Reserve Regiments formed on mobilisation)[8]
In summary, XXXXI Reserve Corps mobilised with 18 infantry battalions, 2 cavalry detachments, 24 field artillery batteries (96 guns), 2 cyclist companies and 2 pioneer companies.
On 2 May 1915 in preparation for the Gorlice-Tarnow Offensive the corps consisted of 18 battalions, 4 squadrons, 43 machine guns and 108 guns. The corps was organized as follows:
