The head of the organisation is Colonel Casey, who not only manages and runs the entire force, she also works with International Rescue and its operatives when the situation calls for it - she has recruited the skills of Parker to break into a vault to rescue a scientist (The Hexpert) as well as for their undercover operation (Undercover). There are times however they do get in the way of a rescue attempt by International Rescue (Earthbreaker) and occasions where they have called the Tracys to offer them assistance (Chain Of Command and Up from the Depths Part 2).
