Captain Tom Sawyer, aged 26, 29 Commando Regiment Royal Artillery, and Corporal Danny Winter, aged 28 and from Zulu Company 45 Commando Royal Marines, were killed by an explosion on 14 January 2009. Both men were taking part in a joint operation with a Danish Battle Group and the Afghan National Army in a location north east of Gereshk in central Helmand Provence. The MoD subsequently confirmed that the men died as a result of a 'Blue on Blue (Friendly fire)' incident, thought to involve a Javelin missile.[http://www.timesonline.co.uk/tol/news/world/asia/article5586166.ece]
