What does it take, both physically and mentally, to join the worlds most respected-and feared-military units? Lewis looks at the origins, training, tactics, weapons, and achievements of regiments such as Britains SAS and Paratroopers, the US Navy SEALS, Delta Force, Army Rangers and Green Berets, Russias Spetsnaz, and the Israeli Special Forces, as well as the codes that bind their members together.

In deepest Siberia, two American scientists are on a mission, to expose the secrets of the woolly mammoth. Their search will lead them to one of the greatest mammoth finds ever uncovered.

The 2013 discovery in Siberia of the best-preserved mammoth yet has quickened the pace of one of the most ambitious and controversial projects in science: the cloning of the woolly mammoth. This one is unlike any mammoth found before; when it was dug out of the permafrost, a dark red liquid oozed from the frozen body. Speculation is rife: could the liquid be mammoth blood? And does the freshness of the mammoth's flesh mean that a clone is now achievable? This documentary follows an international team of mammoth specialists and cloning scientists as they carry out a historic autopsy in Siberia, and follows those who strive to bring these iconic giants of the Ice Age back from extinction. As the animal is carefully dissected and its tusks are examined, the programme reveals the life story of this mammoth in forensic detail.
