A captain in 29 Commando, Johnny Mercer served in the army for 12 years. On his third tour of Afghanistan, he was a joint fires controller, with the pressurized job of bringing down artillery and air strikes in close proximity to his own troops. Based in an area of Northern Helmand that was riddled with Taliban leaders, he walked into danger with every patrol, determined to protect them. Then, one morning, in brutal close-quarter combat, everything changed....

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. Mick Flynn has never backed away from a challenge.

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.

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. Undermanned and suffering from equipment shortages, 3 PARA fought doggedly to win the break in battle. Numerous gallantry decorations were awarded, but they were not without cost. This is a dramatic, and often moving, insight into the leadership of soldiers at the sharp end of war.

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.

Born ‘a ragged-arsed kid from the backstreets of Glasgow’, McCallion joined the Paras to escape a miserable home life and find the family he longed for. 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.

From its early beginnings in World War II, the Special Air Service (SAS) has won renown in some of the most dramatic, dangerous and controversial military special operations of the 20th century. It is a secretive and mysterious unit, whose operations and internal structures are hidden from the public eye. Now, one of its longest-serving veterans offers a glimpse into the shadowy world of the SAS. Rusty Firmin spent an incredible 15 years with 'The Regiment' and was a key figure in the assault of the Iranian Embassy in London in May 1980. 

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. Their mission was to hold the District Centre of Musa Qala at any cost. Easy Company found themselves in a ramshackle compound, cut off and heavily outnumbered by the Taliban in the town.

As a senior non-commissioned officer of Delta Force, the most elite and secretive special operations unit in the US military, Command Sergeant Major Tom Satterly fought some of this country's most fearsome enemies. Tom is a legend even among other Tier One special operators. Yet the enemy that cost him three marriages, and ruined his health physically and psychologically, existed in his brain. Told through Satterly's firsthand experiences, it also weaves in the reasons for his career-long battle against the most insidious enemy of all: post-traumatic stress.

What makes an ordinary but highly educated Englishman, with no previous military training, decide to travel and fight in one of the most brutal conflicts on the planet? Desert Sniper is an extraordinary true account of one man's journey from well-meaning volunteer to battle-scarred combat sniper, placing himself daily in the line of fire to fight one of the greatest evils of this new century.

Kim Hughes is the most highly decorated bomb disposal operator serving in the British Army. He was awarded the George Cross in 2009 following a gruelling six-month tour of duty in Afghanistan, during which he defused 119 improvised explosive devices, survived numerous Taliban ambushes and endured a close encounter with the Secretary of State for Defence.

For the first time, a blistering, highly charged account from the man known as 'Marine A' who was at the centre of the controversial murder of a wounded Taliban fighter. His case led to an unprecedented wave of public support which raised over £800,000 to fund his appeal. The nerve-shredding situations Sgt. Blackman operated within, under sustained attack for long periods, living in the unrelenting horror of a theatre of war, took their toll mentally and physically.

On October 3, 2009, after years of constant smaller attacks, the Taliban finally decided to throw everything they had at Keating. The ensuing 13-hour battle - and eventual victory - cost eight men their lives. Red Platoon is the riveting firsthand account of the Battle of Keating, told by Romesha, who spearheaded both the defence of the outpost and the counterattack that drove the Taliban back beyond the wire and received the Medal of Honor for his actions.

At 24 years of age, U.S. Army Ranger Sean Parnell was named commander of a forty-man elite infantry platoon - a unit that came to be known as the Outlaws - and was tasked with rooting out Pakistan-based insurgents from a mountain valley along Afghanistan's eastern frontier. Parnell and his men assumed they would be facing a ragtag bunch of civilians, but in May 2006 what started out as a routine patrol through the lower mountains of the Hindu Kush became a brutal ambush.

In April 2006, the elite 3 Para battlegroup was dispatched to Helmand Province in southern Afghanistan. They were tasked with providing security to reconstruction efforts, a deployment it was hoped would pass off without a shot being fired. In fact, over the six months they were there, the 3 Para battle group saw near continuous combat, one gruelling battle after another, in what would become one of the most extraordinary campaigns ever fought by British troops.
