+<h2>5. Target prioritization on threat level</h2>
+
+<p>Targets can be detected of different types in one DetectionItem. Depending on the type of the Target, a different threat level applies in an Air to Ground combat context.
+SAMs are of a higher threat than normal tanks. So, if the Target type was recognized, the Recces will select those targets that form the biggest threat first,
+and will continue this until the remaining vehicles with the lowest threat have been reached.</p>
+
+<p>This threat level prioritization can be activated using the method <a href="##(AI_DESIGNATE).SetThreatLevelPrioritization">AI_DESIGNATE.SetThreatLevelPrioritization</a>().
+If not activated, Targets will be selected in a random order, but most like those first which are the closest to the Recce marking the Target.</p>
