Skidskyttelandslagets translates to "biathlon national team". Byström comes from the Norwegian national cross-country team, though he has worked for the Swedish national biathlon team before as a coordinator.
The Swedish national biathlon team has reconstructed its organisation. They did not have a national team manager before, which Anders Byström has been appointed to. The new head coach, as you have written, is Johannes Lukas.
According to Secretary General, Ingemar Arwidson - "The National Team Manager is a new role that we now establish. The idea is that Anders will be responsible for a leading and coordinating role for the A-, Development and Youth teams in order to maximize our resources. He will also be responsible for the national team selection and long-term planning. Anders is a really good leader and I am happy to bring him to the team".
