1.The former Seals were on CIA contract who asked permission to aid the consulate and were denied a couple of times before they decided to do what was needed.
2. There were four people who went to the aid of the consulate, not two. We do not know the names of the other people.
3. There were several attacks that were fought off successfully. The two former Seals were killed by mortar fire. One of them was manning a heavy machine gun at the time.
More details are sure to come out. There were a number of survivors.
Who said they were under CIA contract? It could be, but has that been confirmed or is it assumed?
