Many regiments were renamed and assigned to different divisions during the period from 1871 to 1914. Among other changes, the 3rd and 4th Divisions swapped the Colberg Grenadiers and the 14th Infantry Regiment. In 1914, the peacetime organization of the 3rd Division was as follows:
5th Infantry Brigade
*2nd Grenadier Regiment "King Friedrich Wilhelm IV"
*9th Colberg Grenadier Regiment "Graf Gneisenau"
*54th Infantry Regiment "von der Goltz"
6th Infantry Brigade
*34th Fusilier Regiment "Queen Victoria of Sweden"
*42nd Infantry Regiment "Prince Moritz of Anhalt-Dessau"
On mobilization in August 1914 at the beginning of World War I, most divisional cavalry, including brigade headquarters, was withdrawn to form cavalry divisions or split up among divisions as reconnaissance units. Divisions received engineer companies and other support units from their higher headquarters. The 3rd Division was again renamed the 3rd Infantry Division and the 54th Infantry was transferred to the 36th Reserve Division. The 3rd Infantry Division's initial wartime organization was as follows:
*Colbergsches-Grenadier-Regiment Graf Gneisenau Nr. 9
6.Infanterie-Brigade:
*Füsilier-Regiment Königin Viktoria von Schweden Nr. 34
*Infanterie-Regiment Prinz Moritz von Anhalt-Dessau Nr. 42
Grenadier-Regiment zu Pferde Freiherr von Derfflinger Nr. 3
3.Feldartillerie-Brigade:
*1. Pommersches Feldartillerie-Regiment Nr. 2
*Vorpommersches Feldartillerie-Regiment Nr. 38
1./Pommersches Pionier-Bataillon Nr. 2
Late World War I organization
Divisions underwent many changes during the war, with regiments moving from division to division, and some being destroyed and rebuilt. During the war, most divisions became triangular - one infantry brigade with three infantry regiments rather than two infantry brigades of two regiments. An artillery commander replaced the artillery brigade headquarters, the cavalry was further reduced, the engineer contingent was increased, and a divisional signals command was created. The 3rd Infantry Division was heavily reorganized by 1918, losing all of its prewar infantry regiments. These were replaced by lower grade infantry and Landwehr infantry regiments. The division was also weaker in artillery and engineers than most other divisions. These changes reflected the division's primary role as occupation troops late in the war. Its order of battle on January 10, 1918, was as follows:
6.Infanterie-Brigade:
*Infanterie-Regiment Nr. 425
*Infanterie-Regiment Nr. 428
*Landwehr-Infanterie-Regiment Nr. 4
3.Eskadron/Grenadier-Regiment zu Pferde Freiherr von Derfflinger Nr. 3
Feldartillerie-Regiment Nr. 87
Stab Pionier-Bataillon Nr. 112:
*1.Landwehr-Kompanie/Schlesisches Pionier-Bataillon Nr. 6
