Spartan Rangers

The origin of the Rangers are unknown, but some of the members may have been soldiers from the Russian Army or from the Russian Special Forces (Spetsnaz) before the 2013 Apocalypse. They may as well have been mercenaries or some sort of other armed forces. However it is known that they have been operating in the Metro since the Great War of 2013. The group has always been lead by Miller  who is often referred to as  "The Colonel". The Rangers have also always been the guard and military force of Polis. However, they also act independently. Rangers seem to be greatly feared by the bandits, Reds and Nazis alike. In the level "Dry", a conversation between a few bandits near the rails can be heard. One bandit mentions how a lone Ranger single-handedly took out large groups of men and how nothing in the tunnels can stop them. The bandit also mentioned that they might not even be human because of their fighting skills. Ironically, upon questioning the bandit reveals the group was killed by a "lone Ranger" outside Riga station - the same bandit outpost taken down by Artyom when he was traveling with Bourbon.
