The Kirov novel Eagle Rising, previously reviewed on Fuldapocalypse, has a wargamed out (mostly via the excellent The Operational Art of War) Russian all-out invasion of Ukraine in 2021 with largely realistic OOBs-that ends after a few weeks with the Russians grabbing a chunk of the country but falling short of their objectives and descending into a grinding stalemate. There are of course differences, often erring on the side of spectacle like a brigade-sized air assault into Dnipro at the beginning and, most bizarrely, a counteroffensive crossing the border to hit Belgorod.
It’s described in the book itself after the initial big battles as “All Tyrenkov [the time-traveling Russian leader] has done is buy himself a long war there, and for a lot of blood and steel.”
Like Hector Bywater’s The Great Pacific War, this was strangely prescient in many ways. Even in small details like Ukrainian light infantry succeeding with hit and run strikes. Of course, the background is vastly different, involving a time traveler from the past (Tyrenkov) going forward , seizing control of contemporary Russia, and mistaking a potential future victory for a certain one. But the nuts and bolts are a tribute to both the TOAW simulation and the power of well-designed wargames in general.
