The Opolchenie are Russian militia which served in the Russian armies during the Napoleonic Wars and were especially prevalent in 1812. While mostly engaged in engineering (...digging) field fortifications but some 10,000 were said to be under arms during the battle of Borodino.
With that in mind I made two elements for our game of that huge battle a few years ago.
However I was given some more sprues of what were Warlord Prussian Landwehr (1st Ed) so I decided to add a third more to my militia force. It would take only a bit of scraping removing all the "Prussian" bits and putty adding to some of the pants for the fuller Russian look and of course the full beards as shown in contemporary illustrations.
