Well, If I understand it correctly, the former seals were working for a private security firm, (Blue Mountain). Therefore, their boss would be their superior in the security firm - not the CIA or Pentagon.
But any military assistance they might have received would not have come from their security firm employer. Any request for assistance would had to have gone to the CIA, or some military command.
The statement concerning what the acting CIA director would testify to was fairly vague: that the CIA did not ask for any military assistance, no specificity as to what CIA location, but some commentators interpreted it to be CIA headquarters.
Maybe it has been made more clear somewhere today.
Blue Mountain is reportedly a British firm. Last report I saw stated it was a firm that specialized in pop star celebrity security, not embassy security.
Of course, the only other Blue Mountain company I know of sells greeting cards.
