The Assassin demonstrates its maneuverability.

Because of its high ground clearance and climbing abilities, the MW-77 is able to advance across grades and terrain inaccessible to the common tank. It is equipped with a turbo-charged 2400hp JTU MV 992 diesel engine providing a power to weight ratio of 75.5hp/t. The transmission has a planetary gear train and a hydrodynamic torque converter. It is also equipped with hydro-pneumatic suspension and internal torsion bar springs. The suspension system also provides vehicle attitude control or "kneeling" capability, which increases the main gun depression angle to a maximum of minus 30 degrees.

It is also the first vehicle to incorporate RAMTAC speed-hydraulics, used in conjunction with gyrostabilizers.
