The difficult Ariadnan geography does not allow artillery units to rely on supply lines. With ammunition often limited in quantity, it is imperative that the most is made from the salvos available.

To avoid running out of supplies in the middle of a campaign, the unarmed versions of the Traktor Mul have become the equipment and material transport units for Ariadnan advanced forces. Thanks to the great mobility of these machines, Ariadnan soldiers can always count on an extra quantity of supplies wherever they are.
