In extreme situations, the police have limited time to react when a threat or a situation arises suddenly. Situation awareness has been identified as a key factor for success in how tactical decisions are made. This helps the police to perform secure and legally correct interventions and decisions. We collected the primary data from 21 interviews with police officers, supplemented by literature and documents. We analyzed the relationship between tactical methods and situation awareness. The purpose of the article is to explore the relationship between police tactics and police officers’ work with situation awareness. Situation awareness has been studied through the lens of the Swedish police general tactical explanation model. We discuss how the general tactical explanation model provides the conditions for the police officers’ explanations to achieve situation awareness. We conclude that if the general tactical explanation model is applied during tactical interventions there are better possibilities to achieve situation awareness.
