LONDON  - Nearly half of Britain's troops have regularly considered leaving the country's armed forces, a major survey published Wednesday by the Defence Ministry showed. The research is likely to add fuel to accusations of military overstretch in Britain, which has 7,800 soldiers committed to Afghanistan and a further 4,000 stationed in Iraq. According to the survey, 47pc of Royal Navy and Army personnel said they "regularly feel like leaving the (armed forces) for good", while 44pc of Royal Air Force respondents expressed similar feelings, compared to 37pc in the Royal Marines. Overall, 45pc of armed forces personnel said they were not happy with the level of separation from friends and family, with 38pc of respondents saying it made them more likely to leave the military, though 47pc said it made no difference. Asked to rate morale in their particular section of the armed forces, 72pc of RAF personnel said morale was either "low" or "very low", compared to 64pc expressing similar opinions in the Royal Navy and 59pc in the Army. Just 38pc of respondents in the Royal Marines, however, said morale was "low" or "very low". The survey was carried out between July and October 2007, and questioned 8,857 members of the British armed forces.
