Comparing: Bat.-Châtillon 25 t AP vs. Leopard Prototyp A

In 1950–1951, engineers of the FAMH company (Compagnie des forges et aciéries de la marine et d'Homécourt) worked on the development of a medium tank with a 90-mm gun and a 25-ton rotating turret. Work was discontinued at the preliminary design stage. Later, all elements of the vehicle were incorporated in the Batignolles-Châtillon 25 t tank.

Prototype developed from 1960 through 1961 as a medium tank for the Bundeswehr, with a total of 26 prototypes manufactured. The prototypes were tested up to 1963. The vehicle was the predecessor of the Leopard medium tank.
