13 -Endsley defines team SA as the degree to which each team member possesses the SA required for his or her responsibilities [1]. SA is vital to individual performance, and team SA is critical to good team performance. Team members may have different subgoals in a given trauma resuscitation. **Team SA can be subdivided into 2 types: (1) shared SA, in which team members possess the same SA and (2) complimentary SA, which represents unique, specialty-specific SA necessary for good team performance** [ref id.] (Fig. 1). **Actionable SA** is  realized by integrating SA-support with decision-support functionalities, so that actions can be initiated and guided efficiently and effectively (e.g., see ASSISTANCE's Chemical Hazard module that displays information about gas distributions, its current and predicted future states , with explicit affordances to set safe approach and evacuation routes [2].

22 +How the environmental states are perceived, understood and predicted are determined by the experience and knowledge of the concerning team member. Humans develop and share **mental models** that support both the interpretation of situational conditions and the activation of appropriate behaviors and decisions. This can concern for example the spatial layout ("mental map") of an oil factory, its hazards ("explosive gases"), and the related fire operational procedures (ventilation closure, boundary cooling, ...).  It should be noted that

19 19  * **Situational Awareness Global Assessment Technique (SAGAT)** is a widely used method by periodically freezing the test use case (e.g., a simulation) and querying participants about the status of the environment. There is also a version (Team SAGAT) for assessing shared situation awareness [3-5].
20 20  * **Situation Present Assessment Method (SPAM)** measures SA by requiring participants to answer queries about the environment in real time. Team SPAM focuses on real-time queries to multiple team members to assess their collective awareness [5-7].
21 21  * **Teamwork Situational Awareness Rating Technique (TSART)** is a subjective measure of distributed (team) situation awareness in which team members rate their awareness of other team members’ activities and intentions [8].

38 +Enhancing SA is a primary claim for both our drone and sensor interventions. Participants acknowledged that tools like drones can indeed **enhance situation awareness and efficiency**, but **context matters**. In fast-paced scenarios, they favored minimal setup and real-time feeds for immediate SA, whereas in longer operations more detailed analysis was acceptable. Crucially, responders want technology to support their SA //without supplanting their judgment//. Maintaining **human oversight** of autonomous systems was deemed important so that the team’s situational understanding remains aligned with reality.

1 +Ik zou figuur1 eruit willen halen. Het is naar mijn idee goed om consistent een onderscheid te maken over de kennis die iemand bezit en de geactiveerde gesitueerde kennis ("situationeel bewustzijn"). tijdens de taakuitvoering. Het figuur zorgt voor wat verwarring. In de tekst is het goed verwoord.
