It's not a 1 to 1, but the two core elements of the story are the industrial extermination of an entire ethnicity, and the use of science to build super weapons. The techlevel is late interwar or WWII, best shown by the tank, which is clearly inspired by WWII tanks, not WWI era tanks. The main cast are all officers in the fascist military dictatorship that carried out a war using super weapons against civilians. It's not really subtle.
