Soldiers of the Spanish Civil War (Fictional Work)

This is a broad catch-all category. Fictional characters who served in the OTL version of Spanish Civil War (such as the majority of characters appearing in "The Hill of the Beast") should go here. Those who served in some variant of the war, such as the characters who served in the extended war that was folded into the version of World War II depicted in The War That Came Early, should also go here.
