Self-propelled anti-tank and anti-aircraft vehicles were a key element of the Nazi Army during the Second World War. Anti-tank weapons assumed great importance from the outbreak of war as combatants developed ever more effective armoured vehicles and tactics. Some were little more than stopgap solutions, such as mounting the weapons on a tracked vehicle to give enhanced mobility, while others were more sophisticated designs. Examples of the development of tank destroyer technology throughout the war are the Marders, Jagdpanzer 38, and Nashorn. In order to provide much needed fire power, vehicles like the 5-ton Sd.Kfz.6 halftrack mounted Soviet 76.2mm field guns. The Marder series played a key role supporting armoured operations with their anti-tank guns.Anti-aircraft firepower was vital to give protection to troops from increasingly potent Allied ground-attack. The Germans also mounted anti-aircraft guns onboard halftracks such as the Sd.Kfz.10/5 and 10/4 armed with 2cm Flak guns, the medium Sd.Kfz.7/1 halftrack mounting 2cm flak guns, including quadruple flak guns on certain modified vehicles. Later in the war there was the Flakpanzer 38 (t) with a 2cm flak gun, an Sd.Kfz.6/2 Flak halftrack, and the Flakpanzer IV `Wirbelwind` with a rotating flak gun turret armed with quadruple 2cm flak guns.In true Images of War style the authoritative text is superbly supported by well captioned contemporary images.
