Israelis' invulnerable, 60-tonne robot bulldozer force to double

From the article: "The regular D9, from Caterpillar, is an imposing brute. It weighs nearly 50 tonnes - reportedly more than 60 with IDF armour - boasts better than 450 horsepower, and is generally equipped with a normal bulldozer blade at the front and a "ripper" delving tool at the back. The Black Thunder unmanned version is fitted with cameras and remote actuators, and can operated unmanned or with a driver as may suit."
