Ultimate Force

It's a baptism by fire when new recruits Jamie Dow and Alex Leonard join the SAS's elite fighting force team. Hot on the heels of an explosive hostage-rescue exercise in the regiment's Killing House, Red Troop led by charismatic Sergeant Henno Garvie is called to take command of a bank siege. This time the life or death situation is dramatically and tragically real.

Red Troop of the SAS is back in action when a ship docks at Southampton with a suspicious crew. Jamie and Henno sneak on board to plant a tracker, but the operation goes wrong - they lose radio contact with base and are forced to kill a man. Caroline poses as a customs officer to help them escape, but events get out of control and a tremendous gun battle leaves Red Troop in the firing line.

In Season 3 of this program, terrorists take passengers hostage on a Hong Kong-bound plane, Henno faces down the Al Qaeda and more.

During the fourth season of this program, Red Troop monitor a suspected weapons dealer who leads them into an armed stand-off and more.
