King's Troop Royal Horse Artillery's Captain Jonathan Brooks says the Royal Family were 'out in full force' to celebrate a 'moment in history' with the Queen's Platinum Jubilee.
Captain Brooks said Queen Elizabeth II is a 'huge inspiration to all of us'.
'(The Queen) puts duty ahead of everything else and she really fills the heart of the nation,' he told Sky News host Piers Morgan.
'So to be able to be there and be a big part of marking this historic occasion and hopefully making her proud is unbeatable.'
