On January 21, 2016, even after the Coalition airstrikes and battlefield losses from previous offensives, it was estimated that ISIL still had up to 10,000 fighters defending Mosul, which would require 24,000+ highly trained Iraqi soldiers to dislodge from the city.[52] On January 23, 2016, it was reported that 400+ ISIL fighters had been killed in clashes with the Peshmerga and other local forces, during the past few days.[53]
