Add-on armour is a form of improvisation of the tank armour usually done by the crew or a maintenance unit in the front lines. Due to the rushed nature of tank technology in World War II, armour once considered adequate on tanks can quickly become obsolete with the introduction of a new gun piece in the field or a new equipment, such as the KwK36 (88 mm) on the Tiger I and the Panzerfaust anti ...
