As Israel encircles Gaza City, the Israeli Defence Forces (IDF) is conducting what we in the British Army call Fibua, or Fighting In Built-Up Areas. Less ceremoniously, it’s known as Fish – fighting in someone’s house – or Fish and Chips – fighting in someone’s house and causing havoc in people’s streets. But the flippant name belies the danger – and terror – of these operations.
My taste of Fibua came in 2004 during tank operations in Al Amarah in southern Iraq. While my experience might be a little out of date, the fundamentals of urban combat for tanks haven’t really changed. The tank is a formidable weapon. But when you’re inside one you feel anything but assured: it is impossible to see enough and adequately get your bearings when you have the turret hatches closed down. All you have to go on are the letter-box sized periscopes around your commander’s cupola ring, and the constrained image from your gunnery sight.
