The comparative lack of “tank fiction”, especially non-historical tank fiction, compared to other types of thrillers isn’t really that surprising to me, but it is a little bit disappointing. I can see why that’s the case, because tanks have less (literal and figurative) flexibility than dismounted people, and because they can appear in books without being the absolute center of everything.
Still, when it does appear, I tend to like tank fiction. Tin Soldiers, a tank novel extraordinaire, is arguably my favorite post-1991 technothriller. Although this raises the question of how prominent a tank or other AFV needs to be in a book for it to be considered true “tank fiction”, especially once one gets past the easy cases.
