Ground reconnaissance was supplemented by air reconnaissance. Moreover, reconnaissance units were supposed to destroy enemy cover forces, secure the flanks and contact lines, as well as to chase the enemy. The means of performing these tasks were reconnaissance tanks and armoured cars, as well as motorcycle patrols. Armoured cars could be divided into heavy armoured cars, constructed on six- and eight-wheeled chassis, as well as light armoured cars with four-wheeled chassis and combat weight up to 6000 kg. The basic German light armoured cars (leichte Panzerspähwagen) included Sd Kfz 221, Sd Kfz 222 and Sd Kfz 223. This book focuses only on the light armoured cars (4x4). Old light armoured cars heavy armoured cars (6x4) and (8x8) will be dealt with in a separated monograph, soon to be published by “Militaria” Publishing House.
