The Maus has some weak spots, as shown in the picture. First, the lower section of the side skirts, marked in red, can be penetrated by high powered AP rounds, though generally only from directly side on. The turret cheeks can be penetrated by more powerful HEAT, APCR and APDS rounds, as well as some particularly powerful full caliber AP rounds. Third, a 155mm HE round to the commander's periscope, marked in yellow, will overpressure the crew compartment for a one shot kill.
