This is ASB. The Iranian Army as stated was at the time like a chicken with its head cut off. They were undoubtedly brave but lacked the leadership to really take strategic offences like the one needed to take Basra.
Well, that's part of the reason I made this an AHC too -- I'm looking for a PoD (preferably after 1980) that would allow Iran to take the city, preferably still win the Battle begun 1982. Also, the OP asks that Iran takes Basra -- whether and how they hold it is another matter...
