The HMKG is organized as a light infantry battalion of six companies : Each of the rifle companies takes turns in carrying out guard duty at the royal residences in between other duties . The majority of Guardsmen are National Servicemen who are posted to the regiment after their basic training . On arriving at the battalion from basic training , they spend their first five weeks in ceaseless drill practice , hand-to-hand fighting , physical training , close range firing and case solving exercises before they are allowed to perform their first duties outside the royal palace or around the Royal Family 's country residence . In addition the guards practice specialized operations within their platoons , and whenever a company becomes the oldest unit within the battalion ( longest period of conscription ) , the company enters service as gardestridsgruppe ( guard battle group ) , GSG , with a 72-hour emergency response time . The mission of the GSG is classified , but it was used during the 22 July attacks on Oslo in 2011
