Sky has today announced that Martin Clunes, Dougray Scott and Robson Green will appear in the fourth series of Strike Back.
Currently filming on location in South Africa and Hungary, the new ten-part series will air on Sky1 this summer.
Green (Soldier Soldier) will play Lt Colonel Philip Locke, a commanding officer in chief will join the Section 20 team, while Clunes (Doc Martin) will play Sebastian Gray, a former MI6 agent turned independent intelligence officer working in Beirut. Scott (Mission Impossible II) will play James Leatherby, a wealthy rogue operative and self-styled war junkie.
Robson Green commented: "It is great to be working alongside 'Section 20' and being part of an 'Elite Team' for Sky. Strike Back is a quality drama with incredibly high production values."
Series 4 will see Section 20 will pursue a deadly terrorist network from Colombia to Beirut to Europe where they uncover plots reaching to the West.
Philip Winchester and Sullivan Stapleton will return as counterterrorism operatives Sgt. Michael Stonebridge and Sgt. Damien Scott, with Rhona Mitra also back as Maj. Rachel Dalton.
