The M-9 Armored Combat Earthmover is an amphibious, fully tracked vehicle used to prepare firing positions for artillery, tanks and other weapon systems. It features an 8.7 cubic yard scraper bowl and bulldozer blade. The hydro-pneumatic suspension allows the front of the vehicle to be raised, lowered or tilted to permit dozing, excavating, rough grading and ditching. It has a two-speed winch with a 25,000 pound pull.
The M-9 ACE has two smoke grenade launchers for its own protection and also provides chemical-biological protection for the operator. It is equipped with an aluminum structure, which protects against small arms fire and artillery fragments.
