"When you're involved in a war it's the old saying 'if your name's written on the bullet, there's nothing you can do about it'. So you just banished it from your mind. Of course I was scared on some occasions and anyone who says they aren't scared during an operation probably isn't telling the truth. I know about six people who had no fear. Literally none. Whether that was due to a lack of imagination or because they'd conquered it, I don't know. In fact one was Iain Duncan Smith's father, who was one of my closest friends. But during a war, people are taught to kill and they have the blessings of the authorities to do so, so if it's your life or somebody else's, you want to be quite sure it's not yours."
