This video shows a sport native to the British Royal Navy. It's in memory of a particular incident during the Second Boer War in which sailors quickly brought a gun from their ship to an inland battlefield over rough terrain. Since that time, teams of Royal Navy sailors have competed against each other by symbolically re-enacting this event. As you can see from the above video from 1997, this involves moving field guns over walls, disassembling them, swinging them across a gap with ropes, reassembling them, and then firing three rounds. And that's just stage 1.
