‘A quantum leap forward’ was the expression used by Lieutenant-Colonel Joachim Geist to describe the successful operational test of the Boxer vehicle in Australia in an article on the German Army website. The “Gruppentransportfahrzeug” (GTFz) is the Boxer version used by the German infantry, which was transported in early February 2010 to the Australian Outback, for an operational test under hot and dry and hot and humid conditions.
