Big tank, but not a German one

War History Online has an article about a little-known tank:

No, it’s not the Maus, the massive German tank, which was a lot heavier and slightly bigger, but which never went beyond the prototype state and certainly never saw combat. It is the French Char 2c (photo), a seventy ton behemoth in use between 1921 and 1940.
The Char 2C is the only super-heavy tank ever to attain operational status; a super-heavy tank is not simply a tank that is very heavy, but one that is much heavier than regular tanks of its period. The next operational tank to approach its weight would be the German Tiger II heavy tank of World War Two.
The Char 2C had a loaded weight of seventy tons, partly because of its armor– 45 mm at the front, 22 mm at the sides– but much of it just because of its huge size. The armor was among the thickest of World War One-era tanks though, by modern standards, this would be considered thin. It is still easily the largest tank ever to go into production.
With the tail fitted, the hull was over twelve meters long. Within its ample frame there was room for two fighting compartments. The forward compartment was crowned by a three-man turret (the first in history) mounting a long 75 mm gun, and the second, at the rear of the tank, was topped by a machine gun turret. Both turrets had stroboscopic cupolas. The three independent 8 mm machine gun positions at the front gave protection against infantry assault.
The fighting compartments were connected by the engine room. Each track was powered by its own two hundred horsepower engine, via an electrical transmission. Top speed was fifteen km/h and it came with seven fuel tanks, containing over a thousand liters, which gave it a range of 150 kilometers. The suspension contained forty-five interleaving road wheels on each side, making for a total of ninety wheels on the tank.
The tank required a crew of twelve: driver, commander, gunner, loader, four machine gunners, mechanic, electrician, assistant-electrician/mechanic, and a radio operator. Some sources report thirteen, probably due to pictures of the crews that included the company commander.
Over time, the ten tanks were part of several different units. Their military value slowly decreased as more advanced tanks were developed throughout the 1920s and 1930s. By the end of the 1930s, they were largely obsolete, because their slow speed and high profile made them vulnerable to advances in anti-tank guns.
Nevertheless, during the French mobilization of 1939, all ten were activated and put into their own unit, the 51st Bataillon de Chars de Combat. For propaganda purposes, each tank had been named after one of the ancient regions of France.
As their main value was in propaganda, the giants were kept carefully out of harm’s way and did not participate in the September of 1939 attack on the Siegfried Line. They were used instead for numerous morale-boosting movies, in which they were often shown climbing and crushing old French forts. To the public, they obtained the reputation of invincible super tanks, the imagined dimensions of which far surpassed the actual particulars.
Of course, the French commanders knew perfectly well that this reputation was undeserved. When the German Panzerdivisionen, in the execution of Operation Fall Rot, the second stage in the invasion of France, ripped apart the French lines after 10 June 1940, the decision was made to prevent the capture of the famous equipment.
All were to be sent to the south by rail transport. On 15 June 1940, the railway was blocked by a burning fuel train, so it became incumbent to destroy the tanks by detonating charges. Later Goebbels and Göring claimed the tanks were hit by German dive bombers. This lie was to be repeated by many sources. One tank was, nevertheless, captured more or less intact and brought to Berlin in Germany to be exhibited as a war trophy, until it disappeared in 1948.
