The first major offensive led by the new Assault Detachment was during the first days of the Battle of Verdun in February 1916. Storm troops from the Assault Detachment was used in the first wave leading some units into the French trenches, attacking seconds after the barrage had lifted. This generally worked very well, even though it worked much better against the first trench line than against the less well-known enemy rear-area.
On April 1, 1916, the Assault Detachment was redesignated "Assault Battalion Rohr". Around this time it also increased its size from two to four pioneer companies. At the same time, work began on transforming several Jäger battalions into new Assault Battalions.
