A tech demo of an AI-piloted main battle tank goes horribly wrong and the AI is scrapped. Fortunately for the AI, a forge god several worlds over is in need of a new champion.  Now this sentient main battle tank must learn to survive—or even thrive—in a fantasy world with nothing but its wits... and also a System to supply it with more weapons. This story updates at a rate of one chapter each time classified military information is leaked on the War Thunder forums.  The (at time of writing) 13 previous leaks will be accounted for on a convenience basis. Tank You Very Much, or, as its authors have come to call it, Tanksekai, is a crackfic dreamed up by a community of authors including myself, Aest Belaqua, Crownfall, TheLeakingPen, and KnightOfTheGrey.  All military specs in the fic are guaranteed 100% accurate, and every time you dare to correct us, we will make it even more accurate.
