(From the introduction:)
Major changes with the previous editions are the units, with new Order of Battle and factors. The units also are now mostly "two steppers". The combat table is also different at all, with separte combat tables for coalition and Militant Islamic.
The scenarios are two, one against Iraq and Al Qaeda, and the second also against Iran and Iraq. Turkish and Syrian intervention is possible in both scenarios.
The Advanced rules cover Strategic targets, Airstrikes, Special Operations Forces, Command and Control and Additional Forces
