Its military value was close to 0, if not negative. The 2C was certainly not superior to even a Panzer II. The 2C was superior to german tanks at the time,they just suffered the same fate as early kv-1s which was they were outnumbered and outmanoeuvred For instance, it was the same weight as a Panzer IV, though more 'compact'.The only operational super-heavy in WW2 (in tiny numbers - 10) was the Char 2C, and it was so bad (designed in the WW1 for trench warfare) that the French avoided as much as they could putting it in harm's way not to give the Germans a propaganda victory. The B1Bis was an heavy, certainly not a super heavy. I mean,the closest we got to operational and serving super heavies were the behemoth tanks and multi turreted ones such as the French Char 2b,they did okay but they were outnumbered so meh,early war there was potential,but by mid war there was basically no hope for them

That is why no super heavy tanks were produced in the Cold War, instead all tanks were turned into main battle tanks.
