And these are for regular infantry. By the 2011 Abbotabad raid, PNVGs were already a reliable system in JSOC...imagine what they've been using in the 10 years since that we don't know about.
Yes its the same general concept, but what's happening in ENVG is more than fusion of image output, its using onboard software advanced enough that its able to identify outlines of objects and personnel on the fly, aiding rapid target engagement.
The outlining is not even dependent on body heat and it manages to identify even the radio antennas without ever confusing them with the background or just any moving thing. That's a result of software taught by advanced machine learning.
