Description:
NBFZ Heavy Tanks were 1933 Weimar National Defense Forces to the two major military giants in Germany - large orders under Rheinland and Krupp. This "monster" at the time there was two artillery, a 75 mm one 37 mm. In addition, there are two "Dreis" MG13 car machine guns in front and rear vehicles, with a maximum speed of 25 kilometers in the highway. However, although NBFZ has reached 23 tons, the defense is still a crispy shell. The front armor is the thickness of 20 mm, the side and turret layers are only 6 mm! And this "multi-turret" design concept is obviously "wind" with the T-28 multi-gun tanktan of the Soviet Union.

Of course, NBFZ is also a test product in production. Only five real-in-line lines, but the timing of this German multi-gun tank compared to the first tank was a year, enough to be a "old predecessor" of the World War II.

The five NBFZ real vehicles were launched in 1934 to 36. Of course, the Germans did not expect that these old predecessors can act as a championship role, which is undoubtedly just a teaching equipment for early armored soldiers.
