After the May 13, 1981 assassination attempt on Pope John Paul II by Mehmet Ali Agca, a much stronger emphasis has been made of the Swiss Guards' functional, non-ceremonial roles. This has included extended training in unarmed combat and with issue SIG pistols and Heckler und Koch submachine-guns.<br /><br />Pope Julius II founded the Guard in 1505 to provide a constant core of soldiers to protect the Pope; the Swiss mercenaries were an obvious choice. The official founding date is given as January 21, 1506. The force has varied greatly in size and has even been disbanded. The soldiers' most significant action was on May 6, 1527 when 147 Guards, including their commander, died fighting the forces of Charles V. Since 1859 they have been the only mercenary group permitted under Swiss law.<br /><br />
