How to organise a military spectacular
Some 2,500 troops and six massed bands will march past the Queen on Saturday to mark her Diamond Jubilee, followed by a flypast of over 80 aircraft.
Two days before the Armed Forces Muster at Windsor, members of the RAF Regiment, Coldstream Guards and Royal Navy are practising the guard of honour at London's Wellington Barracks, led by the Royal Marines Band.
