Well, how do they "scan" motions in the first place? Imo, humanity does not have much tech to get about it.
This sophisticated device uses a variety of detectors and advanced computer algorithms to identify moving enemy units.
My idea is to research Motion Scanner after we get hands on Mind Probe.
Lore and Justification:
Since Mind Probe reads creature's stats by probing into its "brain" (Live or Cyber). Mind Probe pretty much can estimate distances to any readable target or simply read its location on map. Key difference between Mind Probe and Motion Scanner would be similar to that of antenna - MindProbe is strictly directional and able to focus on the object at far distances while MotionScanner is
omni-directional thus its range is really limited but detection is more like WiFi-covered area.
I searched the forum but did not see that MScanner was ever dependable on Mind Probe research however it brings novelty and explanation to that item.
