Twickenham's Army v Navy clash is the star billing, a rugby match like no other, unrivalled in terms of patriotic fervour and supported by a sell-out crowd, now over 80,000 strong, roaring on the nation's heroes.
The British Army have dominated the annual fixture since the turn of the century, winning the coveted Babcock Trophy on no fewer than 14 of the last 16 occasions, including the last five; but the RAF shook up the status quo last year by securing the overall Championship, their first since 1994. Could the end of the Army's dominating run of four consecutive championships give the Royal Navy the belief that they can lift the Babcock Trophy this year?
