Michael Stonebridge

Colour Sergeant Michael Stonebridge is one of the two series protagonists, alongside Damien Scott, since Project Dawn. In the series, Stonebridge is an Ex-Royal Marine and SBS (Special Boat Service) Commando working for Section 20, and is married to his wife Kerry. Despite this, Stonebridge has an affair with Section 20 officer Kate Marshall. In Project Dawn, Stonebridge is assigned to collect Damien Scott to identify Latif, a mysterious terrorist. Their working relationship begins somewhat rocky due to the duo's polarising views on tactics. He ends his affair with Kate, but soon afterwards, Kate is killed in a bomb, and Stonebridge temporarily loses focus on his job. When Kerry announces she is pregnant, the wife pressures Stonebridge to leave Section 20. After foiling Latif's Project Dawn, Stonebridge decides to resign.
