10,000 troops took months to take out 300 ISIS fighters...
Why am I NOT optimistic?
A rule of thumb:
To overcome an enemy position, you need a minimum of the next larger formation.
So the battalion (~300), will need a regiment (1000+) or greater, to displace.
This being an unconventional urban battle, plus not taking excessive chances...
squad, platoon, company, battalion, regiment, brigade, division...
