What jumps out is that they do not know who they are killing at all most of the time and that the results are seriously inadequate. There needs to be a rule change. We need to know the name.
That will end the pressure to shoot first. We may even acquire actionable intelligence at the same time. Folks need to be reminded that innocents are not a shooting gallery and such casualties naturally produce more enemies.
The drone is a wonderful war tool not so is the gun. Both need target surety at least and that demands patience.
From the numbers quoted, it is plausible that they got less than thirty five military targets which is similar to the number of sniper targets whose military value is certain.
The drone is excellent for look and loiter operations and that should be the focus. True targets of opportunity will be rare and better produced by sniper teams watching choke points..
