In case anyone else finds this interesting, the DOD has night vision goggles which have nearly-zero latency (all analog), amplify much better than digital cameras, and emit very little external light (hard to spot by adversaries).

This veritasium video at 12:00 shows how these goggles work: https://www.youtube.com/watch?v=UAeJHAFjwPM

That said I wouldn't be surprised if someone in the DOD was buying them for general tech exploration though.
