"They are intended to symbolise the Monarch’s and her nation’s gratitude towards members of the armed forces for their exceptional loyalty and devotion to duty.
But an inspection of the Queen’s New Year and Birthday Honours list has revealed that the honours are awarded far more frequently to officers than to ordinary soldiers.
In the most recent New Years Honours list there were 52 awards issued to members of the Army and Army reserve, but of these 48 went to officers and warrant, or non-commissioned, officers, with only one awarded to a staff sergeant, one to a colour sergeant, one to a sergeant and one to a rifleman.
There was a similar ratio in the Royal Navy, where 21 awards were made to officers and Warrant Officers and only three to more junior ranks."
