I'm curious how the map works in terms of spotting an enemy. In the video, I saw the Viper under Tube and it didn't appear on the map. So, what registers as seeing an enemy for it to appear on the map (or your agent to trigger the voice line of seeing an enemy)? Is it the duration of seeing them, or seeing the head of the enemy (because Viper's head was covered by Tube)?

Sry for shit English and video quality
