I always thought it a little strange at that point in the movie, that the delectable Eva Green - supposedly sister to the uber-Christian King of Jerusalem and wife of a Templar Lord - fetches up in the company of a load of black-clad saracen bodyguards. Who are never seen again.
It's a very dramatic entrance, which is justification enough. But it doesn't make much sense... Although looking again at the still, I see they do have the Jerusalem heraldry on their shields, so maybe...
