Pontifical Swiss Guard

The Pontifical Swiss Guard is a minor armed forces and honour guards unit maintained by the Holy See that protects the Pope and the Apostolic Palace, serving as the de facto military of Vatican City. Established in 1506 under Pope Julius II, the Pontifical Swiss Guard is among the oldest terran military units in continuous operation, having been integrated into the UNSC Army following the Interplanetary War and continuing to operate well into the 26th century.
