If the concept is to inject uniformed enemy soldiers with poison during times of war, I would have to think this is a violation of the 1993 Chemical Weapons Convention and/or the 1972 Biological Weapons Convention, even though it's a delivery system not seriously anticipated at the time those agreements came into being.
Scary stuff that people have not only conceived and planned this sort of thing, but appear to be seeing it through actual completion.
Yes, it is scary because while the justification might originally be for use against enemy forces, the end result would be a tool for this current leftist government and deep state to employ the capability against their POLITICAL adversaries. IMO, a crime of aggression, war crime, and potential crime against humanity. The pretext of “capability against some foreign enemy” is bullshit, IMO.
