The Queen's Commisson is awarded to all officers of the British, Canadian, Austrailian and New Zealand armed forces. It represents Queen Elizabeth II's trust in Her new officer, and sets out his special responsibilities.
Most Commissions are fairly similar. The following text is that which is contained in my own commissioning scroll:
