In this sense the ancient ritual of ‘guarding’ is a charade – or a piece of very interesting ‘theatre’ that constitutes a living history. These guards are professional soldiers trained to fight on the modern battlefield – but also ‘volunteer’ to learn all the required skills to ‘march’, ‘stand’ and ‘patrol’ just like a British Infantry Soldier did during the 17th, 18th and 19th centuries. Once upon a time – soldiers in the British Army used march into battle dressed in these uniforms and behaving in this manner – whilst advancing on the enemy standing in straight ranks and moving slowly but precisely forward with fixed bayonet! As the dead and wounded in the front-line fell to the ground – soldiers in the supporting ranks would move up and take their place without effecting the momentum of the attack!
