From the early stages of World War II the German army began to equip their Panzergrenadiers with armoured half-tracks that would support their panzers in action. They developed the excellent Sd.Kfz 251 series, made by Hanomag, and steadily produced them in their thousands, with over twenty versions seeing service in most theatres of the war.
One of the most useful variants was the 8cm Granatwerfer – a version of the Hanomag carrying the standard infantry mortar. The mortar could be moved round the battlefield quickly and in reasonable safety, its armour shrugging off most infantry weapons and shrapnel. The mortar was most commonly removed from the half-track to engage the enemy, however in extremis it could fire from the safely of the vehicle.
