what is the point of trooping the colour
Trooping the Colour Trooping the Colour is an old ceremony whereby a battalion would fall in by companies and the colour-party would "troop" or march the colours through the ranks so that every man would see that the colours were intact. This was done before and after every battle. This ceremony has been retained through time and is today largely ceremonial.
Flag of Italy Some have attributed particular values to the colours, and a common interpretation is that the green represents the country's plains and the hills; white, the snow-capped Alps; and red, blood spilt in the Wars of Italian Independence and Unification. A more religious interpretation is that the green represents hope, the white represents faith, and the red represents charity; this references the three theological virtues.[2]
