The plotting table consisted of a large irregularly shaped table
on which was painted a large-scale map of the parts of the UK controlled
by the particular operations room. A small wooden block or
tokenwas used to represent a group of friendly and enemy aircraft,
such as a RAF squadron. Such tokens were moved around on the
plotting table by plotters using croupier sticks.
