The Israeli Armored D9 — nicknamed Doobi (Hebrew: דובי; lit. teddy bear) — is a Caterpillar D9 bulldozer that was modified by the Israel Defence Forces, Israeli Military Industries and Israel Aerospace Industries to increase the survivability of the dozer in hostile environments and enable it to withstand heavy attacks.

The main IDF modification is the installation of an Israeli-made armor kit which provides armor protection to the mechanical systems and to the operator cabin. The operator and commander are protected inside an armored cabin ("the cockpit"), with bulletproof windows to protect against bombs, machinegun, and sniper fire. The IDF also developed a slat armor add-on to deflect RPG rounds.

The IDF uses the D9 for a wide variety of engineering tasks, such as earthworks, digging moats, mounting sand barriers, building fortifications, rescuing stuck, overturned or damaged armored fighting vehicles (along with M88 Recovery Vehicle), clearing landmines, detonating IEDs and explosives, clearing terrain obstacles and opening routes to armored fighting vehicles and infantry, as well as structures demolition, including under fire.
