[1] The first ceremonial unit, the 318th Guard Battalion, was established in Bratislava on the basis of the order of the Ministry of National Defense of Czechoslovakia on 27 October 1968.

In addition to being and honor guard for the leadership of the Slovak Socialist Republic, it also performed guard services for the Communist Party of Czechoslovakia and the Government of Czechoslovakia.

After the establishment of the Slovak Republic on New Years Day in 1993, the battalion was transformed into the Castle Guard Regiment, which provided a public duties detachment which would become a separate unit on 1 March 1993.

The uniform also features elements of Slovak folk art, such as a hat with a plume and a cord ornament.

Soldiers of the battalion (mostly NCOs) are for ceremonial occasions armed with a 1080 mm flintlock rifle with steel barrel and a bayonet.
