I was curious if anyone knows of novels set in a fictional world at war with a technology equivalent to that of WW1/2 in our world. I am generally looking for settings that don't have fantasy or science fiction elements, almost alternate history, but involving a world and countries based on, but otherwise unrelated to, our own.
Some examples from other media include: The video game foxhole and the manga series Groundless – Sekigan no Sogekihei, also the series Saga of Tanya the Evil but I am looking for something without magic.
