In 1938, a new "panzer" (English: tank) "kaserne" complex was constructed on the drill area south of the original garrison hospital along Hartmannstraße. Originally called "Panzerkaserne", it was occupied by the 25th "Panzer" Regiment, along with regimental and department staff, and included a new hospital. It was later renamed "Villers-Brettoneux-Kaserne", after the Second Battle of Villers-Bretoneux in the first world war, which saw the first use of German tanks in battle. The two artillery "kaserne" were also renamed. The original artillery "kaserne", which had been home to the 10th Field Artillery Regiment was renamed "St. Mihiel-Kaserne", after the town of St. Mihiel, France, where the 10th Field Artillery fought for nearly two years during the first world war. The new artillery "kaserne" was named "Rheinland Kaserne", in honor of the remilitarization of the "Rheinland" in March 1936 by the German Army. In total, approximately 48 buildings and structures were erected on the drill square between 1935 and 1938. The outbreak of the second world war brought construction on these sites to a standstill.
