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. 

This book is Harry McCallion's blistering account of the history of Britain's war against the IRA between 1970 and 1998. From new insights into high-profile killings and riveting accounts of enemy contact, to revelations about clandestine missions and the strategies used in combating a merciless enemy, Undercover War is the definitive inside story of the battle against the IRA, one of the most dangerous and effective terrorist organisations in recent history.

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.

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. 

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....

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.

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. Saed is defended by Tuareg warriors armed to the teeth with stolen NATO hardware. If Range's team can somehow overcome them, then they will earn themselves gold bullion worth $500 million.

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.

In the summer of 2006, Colour-Sargeant Kailash Limbu's platoon was sent to relieve and occupy a police compound in the town of Now Zad in Helmand. He was told to prepare for a 48-hour operation. In the end he and his men were under siege for 31 days - one of the longest such sieges in the whole of the Afghan campaign.

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. 

In July 2009 Geraint (Gez) Jones was sitting in Camp Bastion, Afghanistan, with the rest of The Firm - Danny, Jay, Toby and Jake, his four closest friends, all junior NCOs and combat-hardened infantrymen. Thanks to the mangled remains of a Jackal vehicle left tactlessly outside their tent, IEDs were never far from their mind. Within days they’d be on the ground in Musa Qala with the rest of 3 Platoon - a mixed bunch of men Gez would die for.  

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. 

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.

It takes a tough mind-set to be a successful sniper, to be able to dig in for days on your own as you wait for your target, to stay calm on a battlefield when you yourself have become the target the enemy most wants to take out. Craig Harrison has what it takes, and in November 2009 in Afghanistan, under intense pressure, he saved the lives of his comrades with the longest confirmed sniper kill - 2,475 metres, the length of 25 football pitches.

Among You is the gripping real-life story of a soldier serving on the front line in Iraq and Afghanistan, and an unforgettable, unflinching account of the effects of post-traumatic stress disorder. Jake Wood lives parallel lives: encased in the glass tower of an international investment bank by day, he is also a dedicated TA soldier who serves on the front line during the invasion of Iraq, later returning to the war zone to conduct surveillance on insurgents.
