Not that I wish to get into an argument, but..............
The Army v Navy match is the last (final) match of the Inter-Services Championship (see
The Babcock Inter-Services Championship | Babcock International Group PLC ). It is not a knock-out, but is a series of scheduled matches in which each of the Services plays the others, culminating in the A v N at Twickenham. Therefore, the last match of the Babcock trophy will always be A v N dear chap!
