Some searching led me to this report from an NGO called "AirWars" [1] which, in connection with The Guardian, reports that "at least 22,679, and potentially as many as 48,308 civilians, have been likely killed by US strikes".

You can't bomb an apartment without also hitting the neighbors. And while we know the US has the the technology to hit a car driver without (physically) hurting the passenger, we also know that this is not the type of technology deployed regularly.

I don't think a drone operator would be naive enough to believe that they are killing exclusively military targets and no one else.
