RBO first saw the light of day back in 2011 - on the 70th anniversary of the start of Operation Barbarossa. It was played at a number of shows during the 2012 season - my report from that year's Triples is in this earlier post. Since then it had been wheeled out a few more times, most recently last week at the Sheffield club.
Here are John, Graham and Martin apparently engaged in the overrunning of the Soviet Union.
And since I know you want to see the toys again, here they are. All 1/100 scale plastic kits from Zvezda.
