With the unleashing of the TK-7 "Bear" on the market, the Germans were furious at first that the new Russian model virtually outperformed the origional KT-13 in so many areas. The Germans decided to counter this ferrocity by redefining the entire "armor destroyer" concept.
By secrative means, the Germans managed to aquire one of the Russians' TK-7Ds. After putting it through very extensive tests (under secrecy of course), the armor was then dissasembled for a thurough examination. With several lessons learned, the Germans went to work from scratch on a machine that would re-define the term "armor destroyer".
The result was, after much undergound development and testing, the TK-24A. Mounting a whole new armor system composed of new ceramic-metallic hybrids, revised joints, and many other developments that are still classified to this day. In performance trials, the TK-24A matches and exceeds that of medium Axels- and putting it into the heavy category.
During the -24's development, an attempt to steal or destroy the prototype was made by an unknown group of middle-eastern commandoes that resulted in a small battle involving the Prototype and the British 322nd Expeditionaries against three squads of unmarked Chinise ZR-6s. In that battle, German Test pilot Seigfried Annon not only proved the worth of the KT-24A in live combat, but also managed to get himself assigned to the first Armor Hunters squadron.
