One of the most unique comics I've read is The Red Star
The Red Star is a comic book series by Christian Gossett set in a sci-fi/fantasy world described by Gossett as "Mythic [Soviet] Russia". The "Lands of The Red Star" were inspired by both Russian folklore and military history. The series is thus heavily reminiscent of a post-World War II Soviet Russia mixing technology and sorcery.
The 'United Republics of the Red Star', often simply called the 'State' in the comic, are shown to be coterminous with the historical Soviet Union in a map at the beginning of the first issue. The main enemy of the first novels, Al'Istaan, is a stand-in for historical Afghanistan and occupies a similar area of the map.
