In short: Originally a civilian earthmover, the Caterpillar D9 has been transformed by the Israel Defense Forces into a heavily armored combat vehicle. Known as the Doobi, it serves as a critical asset for engineering tasks, yet its role in demolishing structures and clearing terrain has sparked intense global human rights scrutiny.

Introduced by Caterpillar Inc. in 1954, the D9 bulldozer was initially adopted for civilian engineering in Israel before being recruited for military service. Over decades, the Israel Defense Forces (IDF) modified the machines to withstand hostile environments, adding armor, machine guns, and grenade launchers. The latest generation, the D9R, features a powerful engine and a crew of two: an operator and a commander. These machines are operated by the TZAMA units of the Combat Engineering Corps, performing tasks ranging from minefield clearing and route opening to the construction of fortifications.

The vehicle's military utility is matched by its controversial legacy. During the Second Intifada and subsequent conflicts in Gaza, D9s were used to demolish thousands of Palestinian homes and structures, a practice critics and organizations like Human Rights Watch have labeled as potential collective punishment or war crimes. The destruction has led to significant displacement, with tens of thousands left homeless. High-profile incidents, such as the 2003 death of activist Rachel Corrie, who was killed while protesting a demolition in Rafah, have fueled international condemnation and legal pressure on Caterpillar Inc. regarding its supply chain.

In response to these concerns, several institutional investors have divested from Caterpillar, citing the company's alleged complicity in human rights violations. For instance, Norway's sovereign wealth fund, the world's largest, divested from the company in 2025 due to its involvement in the occupied territories. Despite this, the IDF continues to modernize its fleet. Recent advancements include the deployment of the remote-controlled 'Panda' D9T and the integration of the Iron Fist active protection system, designed to defend against anti-tank missiles. The D9 remains a potent symbol of the intersection between industrial machinery and modern asymmetric warfare.
