What kind of AA missiles do the insurgents have?

The Independent reports:

A missile fired by insurgents from the ground probably destroyed an RAF Hercules C-130 cargo plane in Iraq with the loss of 10 British special operations servicemen, an interim report by Ministry of Defence accident investigators has revealed.

The inquiry team will now have to determine whether the plane was brought down by a heat-seeking missile designed to reach aircraft at high altitude or was a lucky strike by insurgents using a Sam (surface-to-air) missile which normally has a range of less than 10,000 feet.
