The Special Operations Battalion (Croatian: Bojna za specijalna djelovanja), or popularly BSD was founded on 8 September 2000 when the Special Combat Skills Center from Šepurine and the 1st Croatian Guards Brigade (Croatian: 1. hrvatski gardijski zdrug, a component of the 1st Croatian Guards Corps) were amalgamated. It ceased to exist in 2014, when it was transformed into the Special Operations Command.
