London 2012: Lord Coe applauds armed forces Olympic efforts

London 2012 Chairman Lord Coe has called the armed forces and their involvement in London 2012 one of the "defining features" of the Olympics.

He was visiting a few of the more than 18,000 military personnel providing security at games venues - both in and outside London.

As Clive Myrie has been finding out in the Olympic Park, the troops have also been receiving warm support from members of the public.
