When the construction of the Wehrmacht began, the generals concluded that they would need a vehicle capable of carrying larger loads or larger units of soldiers over larger water obstacles to conduct combat operations. They were supposed to be large watercourses and lakes, but also deep sea bays or straits between the mainland and islands.
It must have happened to you that you found the same photograph of a German tank in two different books or magazines, but each time it had a label with the text assigning the vehicle to a different tank division. Since I am an inquisitive creature, I did not give it and I tried to collect basic data on the marking of tanks, both at the level of higher organizational units such as divisions, and within lower units, at the level of battalions, companies and platoons. Also, a number of photographs of German technology show a large number of different identification marks or flags, which in most cases are often ignored by the authors and some of us are interested in what this means.
