In the anime/light novel Eighty-Six, the authoritarian government of the Republic of Saint Magnolia forces the racially impure to fight numerically and technologically superior enemy forces, with the aim of winning their war while eliminating said people, that have been deported to the front to the last man (and woman); most of the public doesn't know about this, even as propaganda and schoolbooks depict the Eighty-Six (so called because they reside in the 86th district of the republic, a military district no one is supposed to enter or exit) as literally subhuman.
The parallels with real life authoritarian regimes are quite obvious here, but none of them went as far as sending only the undesirable to the front, even as the "right" kind of people were readily available. The in-universe justification here, is that the people of Saint Magnolia wouldn't have approved of the war otherwise, so the government has to keep up appearances and feed them the lie of "automated" combat drones that result in no casualties whatsoever (this is, of course, bullshit), while civilians live their usual lives. Is there any IRL regime that could've done something similar?
