 Sullivan Stapleton plays Damien Scott , a former United States Delta Force operator who is familiar with the antagonists of the second series , and an acquaintance of John Porter . He is recruited by Section 20 to help Sergeant Michael Stonebridge find and rescue the kidnapped Porter . Stapleton describes Scott as cocky , rebellious and arrogant , and that it was good to have somebody like him in Section 20 because " he is the one that usually goes in first and takes the bullets , whereas Stonebridge arrives at the last minute and saves the day . " The actor opined that Scott is chosen for the dangerous role because he is daring and does not have any immediate family members who rely on him . Of Scott and Stonebridge 's working relationship , Stapleton said " they have a professional respect for each other " but start to annoy each other . When the actor first read the script for Project Dawn , he saw himself for the role as Scott . Because Stapleton is an Australian actor , he had to speak with an American accent throughout the series . He was wary whether he did it right because he barely worked with Americans on the show , but believed he did okay when HBO , the network that operated Cinemax , was satisfied with it . Stapleton has signed up for another Strike Back series should it be commissioned .
