Robert Langdon grew up on Billa Kalina Station in the South Australian outback. In 1989 he joined the Australian Army where he served for 15 years before transferring to the Army Reserves. He served as a Section Commander on Operation Plumbob to the Solomon Islands in 1999 and Operation Lorosae in East Timor in 2000. Robert was awarded the Australian Active Service Medal with East Timor clasp, the Infantry Combat Badge and the United Nations Medal for his service overseas. In 2004 he began work as a private security contractor in Iraq and Afghanistan and worked with the US Army, civilian contractors and in medical evacuations. In 2008, Robert was employed in Afghanistan by the U.S. company, The Four Horsemen International. His job was to supervise security operations for the company on such tasks as guarding food and supply convoys, and medical relief expeditions. After serving seven years of a twenty year sentence in Kabul's infamous Pol-e-Charkhi prison, Rob was pardoned by the Afghan President in mid-2016 and returned to Australia. He has always maintained his innocence.
