The nickname "Strikin' ten-six-six" was created by Captain Yohannes Milenko of the 2,536th Heavy Armour Division. During the First Battle of Xorgraria, the 2,536th came under heavy attack from a Grox AT unit, with six AT weapons for every tank in the Eteno divion. It was only because the 1,066th took a great risk in splitting its forces to flank the Grox AT unit and annihilate it that the 2,536th survived with the majority of their heavy tanks intact.
