Let's see-- -
54,000 Iraqi government forces,
40,000 odd Pesh Merga,
Various US Army and USMC artillery units firing in support,
Coalition air pounding the bejayzus out of the environs and approaches to the city.
3 to 8 thousand IS madmen in the city.
A million or so civilian inhabitants give or take 100k.
IMO this is going to be a near run and protracted thing.
The ISF clearly like to win battles without fighting.
IMO IS's most likely CoA (course of action) is to seek to make a prolonged and suicidal defense of the city taking advantage of the ISF's great sensitivity to its own casualties. A thousand man stay behind force, indifferent to their casualties, fighting from ruined buildings and also indifferent to civilian losses can make a prolonged and expensive fight.
It is sadly amusing to see how favorably the Borgist media gaze benignly at the approaching spectacle while howling in rage at the impending defeat of their jihadi friends at Aleppo. pl
