Disturbing footage of Apache attack helicopters killing people in Afghanistan is being shown to frontline British soldiers in Kill TV nights" designed to boost morale. The discovery of the practice ... casts fresh questions over the conduct of soldiers deployed abroad and has provoked a furious response from peace campaigners. Andrew Burgin from Stop the War ... described it as the "ultimate degradation of British troops", comparing it to the desensitisation to death of US soldiers in the final stages of the Vietnam War. The footage ... shows ground troops at the British headquarters in Helmand province, Camp Bastion, gathered for a get-together said to be called "Kill TV night". It shows an Apache helicopter commander admitting possible errors of judgement and warning colleagues not to disclose what they have seen. "This is not for discussion with anybody else; keep it quiet about what you see up here," he says. "It's not because we've done anything wrong. But we might have done." Much of the footage is along the lines of the now infamous video of a US Apache helicopter strike on civilians in Baghdad in 2007, first released on WikiLeaks last year. In one clip an Afghan woman is targeted after a radio dialogue between pilots refers to her as a "snake with tits".
