The Tigerfibel and Pantherfibel were crew instruction manuals for the German tanks of World War II, the Panzer VI Tiger heavy tank and the Panzer V Panther medium tank.
Like other manuals designated as Fibel (basic primer), they were apparently intended to summarise what the crew needed to know for day-to-day use of the tank, and to capture their interest. It is well illustrated in comic-style and much of the text is written as poetry in a humorous manner. The Fibel such is remarkably different from the typical tedious style of a German tank manual of that period.
The manuals were approved by Heinz Guderian, the Inspector-General of Panzer troops. In the case of the Panther manual, he issued his approval in the manual's rhyming style, ending with the words, Die Pantherfibel ist genehmigt; wer sie nicht kennt, der wird erledigt (roughly "The Panther fible is approv'd; who knows it not will be remov'd." )
