Pontifical Swiss Guard

The Pontifical Swiss Guard, also known as the Papal Swiss Guard or simply Swiss Guard, is an armed force, guard of honour, and protective security unit, maintained by the Holy See to protect the Pope and the Apostolic Palace within the territory of the Vatican City State. Established in 1506 under Pope Julius II, it is among the oldest military units in continuous operation and is sometimes called "the world's smallest army".

The Swiss Guard is recognised by its Renaissance-era dress uniform, consisting of a tunic striped in red, dark blue, and yellow; high plumed helmet; and traditional weapons such as the halberd. Guardsmen perform their protective duties in functional attire and with modern firearms. Since the assassination attempt on Pope John Paul II in 1981, the Guard has placed greater emphasis on its nonceremonial roles and has sought more training in anti-irregular military counterintelligence, commando-style raids, counter-sniper tactics, counterterrorism, close-quarters battle, defusing and disposal of bombs, executive protection, hostage rescue, human intelligence, medical evacuation, reconnaissance, tactical driving, tactical medical services, and tactical fast shooting by small arms.
