The M88 HERCULES (Heavy Equipment Recovery Combat Utility Life Evacuation System) tracked armored recovery vehicle is built on a unique chassis modified from the previous-generation M60 Patton tank, and can tow or winch any American vehicle out of trouble, up to and including the 70-ton M1 Abrams battle tank. They also carry a hoist and boom with up to 35 ton capacity, for operations like engine changes in the field.
Production of the much-improved M88A2 variant began in 1994, and has continued steadily. HERCULES ARVs serve in a number of countries. Iraq is the latest addition to the type’s operating roster, via refurbishment of former US Army vehicles. In July 2011, the US military ordered more.
