Americans do Civil War and Revolutionary War re-enactments. The Russians go just a bit further back in time… about a millennium, in fact, when the Rus (what they were called then) were big noise in their immediate neighborhood, busy building the cultural foundation upon which Vlad the Impaler created his domestic and foreign policy.
These folks are obviously having lots of fun. I have to wonder if anyone snuck an AK-47 (another Russian invention) into their saddlebags.
If you enjoy the photos, there are lots more, some fairly fun, here.
