Move Over AAA, Make Way For This 140,000-Pound-Capacity Hauler
From pulling the statue of Saddam Hussein down in 2003 to clearing vehicles hit by roadside bombs to its rebuilding tasks in Afghanistan today, the M88A2 Hercules performs many labors. This is the tow truck our military calls into action when one of our M1 Abrams main battle tanks needs a ride on the hook.

The M88A2 is based on the M88 and M88A1 medium-weight recovery vehicles designed in the ’60s by Bowen McLaughlin York. The vehicle’s chassis is based on parts used in the M48 Patton and M60 tank. The key upgrades of the M88A2 (from the M88A1) include improved power steering and braking, an updated electrical system, and increased horsepower.
