Kos's hiring was announced following the appointment of former Slovenian Olympian Marko Dolenc as the head of the national biathlon assembly at the Ski Association, which oversees the national team.

In addition to Kos, Dolenc has appointed former Slovenian biathlete Janez Ožbolt as head of biathlon teams.

The overhaul comes after the departure of Uroš Velepec as head coach and a vote of no confidence to the leading officials of the national biathlon assembly by representatives of clubs earlier this month.

Slovenia's best biathlete, Jakov Fak, also recently publicly indicated that he was in favour of a change at the helm of the team, feeling that this would be beneficial for his results.

Kos returns to Slovenia after having served in various roles with the Slovenian team from 2000 to 2014.
