Swiss Guards are Catholic Swiss nationals who have completed training in the Swiss army before applying to the Vatican. Their oath of office is:
"I vow to faithfully, honestly and honorably serve the reigning Pope [name of Pope] and his legitimate successors, and to dedicate myself to them with all my strength, ready to sacrifice, should it become necessary, even my own life for them. I likewise assume this promise toward the members of the Sacred College of Cardinals during the period of the Sede Vacante of the Apostolic See. Furthermore, I pledge to the Commandant and to my other superiors respect, fidelity, and obedience. I swear to abide by all the requirements attendant to the dignity of my rank."
