analyses, analysis was made in two steps: first the influence of reliability level of the alarm for all scenarios together and then, scenarios were separated to two groups: with UAV feed and without UAV feed due to understanding that using display from UAV changes operators' scanning pattern (Ophir-Arbelle et al., 2012). The interaction between reliability level of the alarm system and the presence of the UAV display is shown in Fig. 3. Method. In 4 operational scenarios, 40 participants, all infantry soldiers with combat experience, were asked to detect and identify suspicious vehicles entering and leaving a hostile building via an interface that presented video feeds derived from unmanned ground and aerial views (Fig. 1). A visual alert system (yellow rectangle, Fig. 2), in one of four levels of reliability: High level, Medium level, Low level and no alerts was available. The alerts conveyed the occurrence of events that required operators' immediate attention.
