The CSHT Mark I Mastodonte (English: Mastodon) was a Cacertian super-heavy tank developed during the last years of the Siduri War as a breakthrough armored vehicle to breach Syaran defenses in Ruvelka and as a possible component to a planned invasion of Syara itself. Unlike standard Cacertian armored warfare doctrine at the time, which focused primarily on maneuverability, the Mastodonte was very heavily armored. The 305mm of armored plating was designed specifically to protect against the 75mm anti-tank guns commonly used in the Army of the Syaran Republic. However, such protection meant that the Mastodonte’s maximum speed was only 13 km/h.
Ultimately, only two prototypes were built and the Mastodonte was still undergoing testing when the war ended in February 1938 which resulted in the project’s cancellation. One example of the vehicle survives and is on display at the Museum of Armored Warfare in Anzio.
