Dressed in their Ceremonial Day uniforms, 176 service men and women will take part as flag bearers in 100 Team Welcome Ceremonies and 805 Victory Ceremonies.
The personnel have been chosen through a Ministry of Defence nomination process, highlighting those who have seen sporting or operational achievements or are involved in their local community.
London 2012 Organising Committee Chair Seb Coe said: ‘The flag-raising duties at Olympic and Paralympic Games are seen as honour, but we are in fact honoured to have these inspirational men and women be part of London 2012.'
About the Ceremonies
The Team Welcome Ceremonies will formally welcome over 200 Olympic teams and over 170 Paralympic teams to the Games, and include the protocol of raising flags.
Victory Ceremonies take place after a medal event finishes and provide a chance for athletes to formally celebrate their success. Following the award of medals, the flags of the athletes' countries are raised, while the national anthem of the country of the winning athlete is played.
Lieutenant Alex Davis said: ‘I am very proud to have been selected to represent the Royal Navy and contribute to the Olympic and Paralympic Games. This is a once-in-a-lifetime opportunity and I am really looking forward to being involved in London 2012.’
Squadron Leader Lee Cobley said: ‘My father represented Great Britain at Melbourne 1956 and Rome 1960 so the Games hold a special fascination for me.
'As a keen athlete and organiser of RAF Squash for many years it always feels good to put something back into sport, and what greater way is there than assisting at the Olympic and Paralympic Games?’.
