With a ground clearance of 48 cm (18 in.), the Abrams tank can climb over obstacles that are 1.07 meters (3.5 feet.) high and 2.74 meters (9 feet) wide. They can ford rivers up to 1.22 meters (4 feet) deep without preparation , and up to 1.98 meters (6.5 feet) deep with the use of a fording kit. The new T-158 tank track has a longer life span than earlier track, and the removable rubber pads make it more cost effective.
On November 27, 2004 an Abrams tank was badly damaged from the detonation of an extremely powerful improvised explosive device. The IED consisted of three M109A6 155 mm shells, with a total explosive weight of 34.5 kg, that detonated next to the tank. The tank's driver received lethal injuries from shrapnel.
