It doesn't. Mosul's civilian population were Iraqi citizens, the conflict was much larger, lasted a lot longer, used smaller munitions, resulted in a lot more military deaths and significantly less civilian deaths. This is despite the enemy being significantly better trained, better equipped, better logistics, years of preparation and less intelligence by the anti-ISIL coalition.
> resulted in a lot more military deathsYeah, they lost a lot of infantry forces and it's probably the reason there were less civilian deaths.
