Highlights / Abstract
• This article examines how the transboundary coordination capacity between the military and the police has changed since the terrorist attacks in Norway in 2011, focusing on transboundary coordination capacity.

• We address changes in the arrangements that regulate how the police can ask for assistance from the military during a crisis and how the military and the police cooperate to implement the regulations designed to protect important public buildings and facilities.

• The processes and the outcome are analyzed from a hierarchical perspective, a negotiation perspective and an institutional perspective.

• A main finding is that there are a lot of transboundary coordination challenges, which can mainly be explained from a negotiation and a cultural perspective.

• Both path dependencies and negotiations constrained the process and led to incremental changes.

• In the field of terrorism there is a grey-zone between the military and the police resulting in a turf wars between the ministry of Justice and Public Security and the Ministry of Defense of who is responsible for what.
