Rohr neglected the tactical training of the army up to the Battle of Verdun. The successful testing of the new methods was carried out by Infantry Regiment No. 187 west of Colmar in the Vosges. The Sturmabteilung Rohr was committed to the re-conquest of the Hartmannsweiler Kopf in December 1915. When its next deployment, the attack on the Hirzstein, failed, it withdrew to carry out more intensive preparations. After completion of the preparations, the place was captured with the help of two regiments inexperienced in battle, Nos. 188 and 189, in January 1916. By successfully employing the Storm Detachment in various sectors of the front, Army Detachment Gaede trained itself and the stationary troops. In December 1915, the first training course in the technique was held in the general's presence on the Schlossberg at Achkarren As a result of its success the detachment was moved in February 1916 to the 5th Army (Crown Prince Wilhelm) to take part in the Verdun offensive.
