going to be? let's say they rye take ramadi and go to mosul. how will that be different? >> mosul will be very tough. general, as the general knows better than anybody, much larger iraq, second largest city. i think it's fair to say that the tactics that will be used will be similar. they will have to basically cut off the isis supply lines in and out of the city. that will keep isis from being able to reinforce itself. also keep isis fighters from being able to run away. cut off the supply lindz, begin to encircle the city, and move closure and closure. you are already seeing stepped up coalition air strikes in that area.
