The Caterpillar D7 is based on a civilian bulldozer with some improvements for military use. The military version of the D7 is produced by Caterpillar Defense & Federal Products company. In the U.S.Army, the main role of this bulldozer is earthmoving.

The D7G can be equipped with a detachable blade. Various blades can be fitted. The most common are short and straight blades without side wings and universal blades with side wings, which allows carrying more material. Also, there are angle blades, two-way blades, and so on. Some D7 dozer are fitted with a rear-mounted rake attachment.

The US Army used armored D7G to clear minefields and unarmored D7G and D7H for earthworks. The armor was developed by the Israel Military Industries (IMI). Later, the US Army developed a remote-controlled version of the D7G for mine-clearing applications.

The D7G is operated by a single operator and is powered by a Diesel engine developing 200 hp. It has a weight of around 23 tons and can run at a maximum road speed of 15 km/h.
