After six tense tours in Ulster, McCallion gave up everything to move to South Africa in the hope of qualifying for the highly elite South African Special Forces. Having succeeded in joining the Recces, McCallion was involved in plots to assassinate Robert Mugabe and Joshua Nkomo.

Michael Asher served in Northern Ireland with the Paras at the height of the IRA campaigns of the 1970s. He witnessed the result of using highly motivated assault troops in 'peacekeeping operations'. His depiction of the strengths and weaknesses of the British Army's elite airborne forces comes from his personal experience of what it was like for ordinary soldiers. From the Paras to the SAS and then service with the Special Patrol Group in Northern Ireland, Michael Asher's military odyssey eventually led him to leave the forces for a new life in the Sudanese desert. 

Peter Ratcliffe served in the SAS for 25 years. Blooded in Oman in the 1970s, he also saw action in Northern Ireland, in the Falklands War, and in the Gulf campaign. From his early days in the Paras to his time as Regimental Sergeant-Major in the Gulf, he has lived and fought by the motto 'who dares wins'. Eye of the Storm is his insider's account of that exceptional career. 

Former SAS soldier Big Phil Campion tells it like is in this brutally honest account of his insanely dangerous life as a private military operator. From playing chicken with a suicide bomber in backstreet Kabul to taking on pirates with his bare hands, this is true-life action-packed drama at its best. 

Simon Chase's life is a maze of burner phones, encrypted emails, secret meetings and weaponry - all devoted to executing missions too sensitive for government acknowledgment. Working for British government entities, the CIA's Special Activities Division and other official bodies, Chase has been on the trail of bin Laden in Afghanistan, protected allied generals in Iraq, and been part of an operation directly related to the attack in 2012 on the US consulate in Benghazi.

Rob Driscoll, former sergeant with 42 Commando, Royal Marines, served tours in Iraq, Kuwait and Kosovo. A born leader of fighting men, with the medals to prove it, he also endured three tours in Afghanistan. The third of those will go down in history as one of the UK military's darkest hours, for it marked the first time a British serviceman has been tried for a murder on the battlefield since the Second World War.

In early summer 1982 - winter in the South Atlantic - Argentina's military junta invades the Falklands. Within days, a Royal Navy Task Force is assembled and dispatched. This is the story of D Squadron, 22 SAS, commanded by Cedric Delves. The relentless tempo of events defies belief. Raging seas, inhospitable glaciers, hurricane-force winds, helicopter crashes, raids behind enemy lines - the Squadron prevailed against them all, but the cost was high. 

It is difficult to find another soldier's story to equal Captain Darrell Watt's in terms of time spent on the field of battle and challenges faced. Even by the lofty standards of the SAS and Special Forces, one has to look far to find anyone who can match his record of resilience and valor in the face of such daunting odds and with resources so paltry. In the fight, he showed himself to be a military maestro. After 12 years in the cauldron of war, his cause slipped from beneath him, and Rhodesia gave way to Zimbabwe.

3 PARA was the first unit into Helmand in 2006. Sent on a peace mission, it became engaged in a level of combat that had not been experienced by the British Army since the end of the Korean War.

This is a dramatic, and often moving, insight into the leadership of soldiers at the sharp end of war.

Sultan Gadaffi has escaped from Libya with a fistful of dangerous secrets. The British Government want ex-Special Forces operative Steve Range, the go-to man for any Black-Ops missions, to lead an ultra-covert mercenary group to seize him from his near-impregnable desert stronghold.

The story of one of the Afghanistan war's most decorated units and their 15-month ordeal, culminating in the Battle of Wanat, the deadliest battle of the war. A single company of US paratroopers - calling themselves the "Chosen Few" - arrived in eastern Afghanistan in late 2007 hoping to win the hearts and minds of the remote mountain people and extend the Afghan government's reach into this wilderness. Instead, they spent the next 15 months in a desperate struggle, living under almost continuous attack, forced into a slow withdrawal, and always outnumbered by Taliban fighters.

We all have break points to face - at the gym, in the office, in our personal lives - those moments of self-doubt where we have to dig deep and find something within to grab hold of and push us through. Ex-Special Forces soldier Ollie Ollerton has faced his own break points, and now he tells us the lessons he has learnt along the way. From survivor of a freak childhood attack to elite fighter, Ollie's incredible story features high-speed shoot-outs, counter-terrorism and humanitarian heroics.

Summer 2006, Afghanistan: an apparently deserted village, and a rapidly ticking clock... The relentless Taliban ambush which followed saw several British soldiers dead, two armoured vehicles destroyed - and Corporal of Horse Michael Flynn awarded an MC to go alongside his Conspicuous Gallantry Cross.

They were branded as cowards and accused of being the British Special Forces Squadron that ran away from the Iraqis. But nothing could be further from the truth. Ten years on, the story of these sixty men can finally be told. In March 2003 M Squadron - an SBS unit with SAS embeds - was sent 1,000 kilometres behind enemy lines on a true mission impossible, to take the surrender of the 100,000-strong Iraqi Army 5th Corps.

In Helmand province in July 2006, Major Adam Jowett was given command of Easy Company, a hastily assembled and understrength unit of Paras and Royal Irish rangers.
