I served as a strike cell attorney in Baghdad during the Daesh fight (Operation Inherent Resolve).

Specific criteria are classified, but the U.S. military systematizes the four LOAC principles: military necessity, distinction, proportionality, no unnecessary suffering.

Positive identification goes only to the first two principles, and—while I don't know specifics—the DoD's "human in the loop not on the loop" AI philosophy makes me think that AI won't satisfy PID by itself. In addition to that, all munitions targets would have to meet CDE in accordance with CJCSI 3160.01. In my experience, there is typically a CDE expert as well as a lawyer involved in every targeting decision.
