Human soldiers kill civilians and other soldiers on the same side. It is called "friendly fire". It is horrible, and should be avoided, but humans are more likely to make this kind of mistake more than a computer or AI model.

Based on?
The JSM has at least one multicore computer + IR camera + RF homing for target identification (plus GPS, terrain matching/following and inertial for navigation). It can automatically identify not only the best target (and recognize and ignore decoys etc), but also the optimal weak spots to impact.
Heck, check the American drone war crime video Wikileaks published. The one that made the USA so angry that it decided to attack and destroy the journalists.
With the USA the stats are available and no valid excuses exist to throw the data away. The US military is not defending itself and is supposed to be the most powerful, advanced (tech and policy) and professional military in the world. They are the best case scenario for the human drone operators' performance one has. And yet:
A computer is unlikely to go "colonel Kurtz".
