Elite women soldiers prepare for South Pole expedition
Lieutenant Jenni Stephenson, who is based at the Army's Larkhill Barracks in Wiltshire, is preparing for a very special challenge.
She is one of seven elite women soldiers about to trek across the South Pole unaided as part of their extreme endurance testing.
The team has just returned from a trial run in Norway where they practised digging out snowholes, being rescued from a crevasse and cross-county skiing.
