Slowed by that engagement, difficult road conditions and fuel shortages, at 4:10 . on October 3 the division was reorganized into two new Kampfgruppen. The right (southern) battle group consisted of the 90th Panzer Reconnaissance Battalion, the 10th Motorcycle Battalion and the 89th Motorized Rifle Regiment. The left (northern) battle group included the 7th Panzer Regiment and one light reconnaissance troop. All of the division artillery was attached to the groups and moving in column with them. Artillery support would be especially responsive because the artillery was moving with the units. The commander and headquarters of the 90th Artillery Regiment moved with the southern battle group and had the radio communications capability to mass the division firepower. Central control of fire in this mobile advance was virtually impossible, however, because the two battle groups would advance too far apart and would face encounters too different and widely separated to permit centralized control of artillery. Fischer ordered the two battle groups to continue to move through the evening of October 3, converging on Mosalsk from two different directions.
While the original concept of Kampfgruppe is usually reserved to the land warfare , some of the German tacticians and strategist applied it also for naval warfare . The most obvious change was the design (units were usually earmarked for operation in advance instead of being organized ad hoc) and the type of units involved (instead of combined arms, different classes of naval vessels were employed). The examples include German Kampfgruppe 5 employed during Operation Weserübung . This unit consisted of the heavy cruiser Blücher , the heavy cruiser Lützow , the light cruiser Emden , 3 torpedo boats and 8 minesweepers carrying 2,000 troops to Oslo .
