John and Doves,
It looks like China has the edge on unmanned nuclear Tanks:

Russia also has AI Tanks:

One wonders if Rev. 9:14-19 is somewhat of a description of these tanks. Too hard to tell yet.
It must have been hard for John the Revelator to describe modern warfare without the vocabulary we use today.
(But it's a lot better than if I had tried.)
Maranatha,
