No, they are not providing armed security, other than protecting themselves whenever they move around. There's no stand-alone force protection role other than what everybody does all the time to defend themselves.
I can't go into the specifics, sir, but they conduct operations to support and assist Iraqi security forces in ensuring that any pockets of ISIL or Daesh do not re-emerge. It's the connection of intelligence to activity. Then, where necessary, if the Iraqi security forces need to act, whether it's to conduct a detention operation, to seize or arrest someone, or to attack, they're supported in terms of their planning of those operations.
