 Not entirely satisfactory, significant chassis redesign was required, though this ultimately provided the basis for improvements in the combat tank line as well.To increase space for a unit commander, radio operator, and a FuG 6 radio transmitter with associated gear the rotating turret and main armament of the Panzer I combat tank was removed.A tall, fixed superstructure was installed which contained space for the commander and radio operator to work, and a single ball-mounted machine gun was mounted in the front armor of this to give the tank a measure of defensive firepower.
