British Army Oath of Allegiance
All soldiers must take an oath of allegiance upon joining the Army, a process known as attestation. Those who believe in God use the following words:
I (your name), swear by Almighty God that I will be faithful and bear true allegiance to Her Majesty Queen Elizabeth II, her heirs and successors and that I will as in duty bound honestly and faithfully defend Her Majesty, her heirs and successors in person, crown and dignity against all enemies and will observe and obey all orders of Her Majesty, her heirs and successors and of the generals and officers set over me.
Others replace the words "swear by Almighty God" with "solemnly, sincerely and truly declare and affirm"
