The Grenadier Guards are the most senior infantry regiment in the British Army. Celebrating their 350th anniversary in 2007, they are are probably best
recognized as one of the five regiments of Foot Guards who stand watch outside Buckingham Palace come rain or shine. It is easy to forget – as you see them
changing the guard to the sound of a military band – that this regiment has also been involved in almost every major British campaign since its formation
through to the present day. Guarding the Queen takes viewers behind the scenes to see what life is really like for these celebrated soldiers.
