However, this definition can also be blurred because as the war dragged on, the German war machine could produce fewer and fewer half-tracks and or trucks for which the Panzergrenadiers to use, thus forcing many units to rely on horse drawn supplies/weapons. Also adding to the confusion was the fact that in order to increase German troop morale, regular infanterie (Infantry) divisions were renamed to panzergrenadier divisions without strictly being trained as such.
