Members of the SWAT Team of the Portland Division of the FBI prepare to enter the interior of a ship during counter terrorism training, May 2013.
The Portland FBI SWAT team specialize in maritime tactical operations and regularly conduct training aboard vessels.
The maritime role requires special training in boarding techniques, such as vertical fast-rope insertion from helicopters, and boarding from small boats such as rigid hull inflatable boats.
Close Quarters Combat (CQC) in the often cramped and labyrinthine interior spaces of large vessels presents unique challenges to tactical operators.
