Ultimate Force
Ultimate Force is a British television action drama series that was shown on ITV, which deals with the activities of Red Troop of the SAS (Special Air Service). The first episode was broadcast on 16 September 2002, and a total of four series were produced. The series starred Ross Kemp as central character Staff Sergeant Henry 'Henno' Garvie. The show was initially described as a star vehicle for Kemp, who had been lured away from the BBC to ITV with a multimillion-pound contract. Kemp appeared in every episode of the four series. 
The series was co-created by Chris Ryan, a former British SAS soldier who was a member of the famous Bravo Two Zero patrol during the 1991 Gulf War. The series was produced by Bentley Productions.

Background
As well as his behind the scenes role, creator Chris Ryan appeared in the first series of the show playing Blue Troop leader Johnny Bell. 
A number of the cast featuring in the first two series did not return to appear in the third series, resulting in a change of characters.
Domestically, the change of format seemed to produce diminishing returns for ITV. The third series was abruptly taken off air by the network midway through the run, only to return a few weeks later. The show was then moved to Saturday evenings at 9 p.m. A similar fate awaited series four, which was pulled after just two episodes. The three remaining episodes of the fourth series were not originally shown on ITV, but shown on ITV4, in January and February 2007. ITV showed the remaining three episodes of the series over a year later, starting on 18 May 2008. The DVD of the fourth series had previously been released on 25 September 2006. ITV then announced there would not be a fifth series, partially due to low ratings—hence the cutting of series three and four midway through their runs—whilst many of the stars moved onto other projects. 
Ross Kemp went on to host a series of documentaries following the progress of British Army troops in Afghanistan, whilst both Sam Callis and Christopher Fox joined ITV's police serial drama The Bill portraying both Sgt Callum Stone and DS Max Carter respectively from 2007 to the end of 2010. Notably, a large number of plotlines throughout the series were left unanswered: most notably, the killing of Iain Macalwain by Henno, the conflict in Pete Twamley's marriage, and the murder of Jamie Dow's step dad, who is hinted to have been killed by Ricky Mann. DVD sales of the first two series resulted in more than £700,000 of revenue by the arrival of the third series, with both regular and limited edition sets making the top ten of the television sales charts. The series has also been aired in 120 countries, ranging from Europe to Southeast Asia.
