Col Borton also said that a shortage of batteries meant that in an effort to save power, junior commanders were often forced to turn the radios off until they came under attack. He added: "The only way to tell how much power a battery has left is to remove it from the radio – that's a serious design fault. In a bid to preserve power, my section commanders only have their radios working when they are in contact. As far as I am concerned, Bowman is astonishingly bad; it is a broken system," he told commanders.
