I was always in awe of the British gun competitions, where
the teams have to dismantle the gun(I don't remember what kind, small maybe 3 pounder?), cross a ditch, go over a wall, through a door way, set up and fire, then go back and set up and fire. Archaic and a good way to lose a finger or two, generally appeared to be something in the way of casualties no matter how well it went.
FIELD GUNNERS: The annual competition at the Royal Tournament gained a reputation as the hardest team sport in the world.
