Caterpillar is a U.S. American firm that manufactures and provides bulldozers and civil engineering tools. It sells bulldozers to the Israeli army that are weaponised and used in the systematic demolition of homes and civilian infrastructure as part of the Israeli army's doctrine of urban warfare. The Caterpillar sales are covered under U.S. military aid to Israel. Caterpillar bulldozers have been used in war crimes in South Lebanon, the West Bank, and the Gaza Strip. They have also been used to demolish Palestinian homes in the West Bank as an arbitrary punitive measure and to build the Separation Wall and illegal settlements on occupied Palestinian land.
The Israeli army used unmanned D9 bulldozers (Dawn Thunder) in the December 2008 attacks in Gaza, and has been using an unmanned version of the company's smaller vehicles (Front Runner) which are specially developed for urban warfare.
In June 2012, Caterpillar equipment was used in the construction of the Tel Aviv-Jerusalem high speed rail. The train's route crosses the Green Line near the Palestinian villages of Bet Surik and Beit Iksa, close to Jerusalem. The tools were documented working on the 3A tunnel site, a of the railway which passes on Palestinian land.
