What is the primary function of lower gears in the JLTV?

The primary function of lower gears in the JLTV is to provide more torque for driving. Lower gears are designed to amplify the power generated by the engine through increased torque, which is especially beneficial in off-road conditions or when the vehicle needs to navigate challenging terrain, such as steep hills or rugged environments. This increased torque helps the vehicle get moving from a standstill and maintain control while ascending or descending inclines.

In contrast, higher gears are typically used for achieving greater speeds but may lack the power needed for challenging driving circumstances. The use of lower gears enhances the vehicle's ability to perform in various tactical and operational scenarios, aligning with the military's need for versatility and reliability in the field.
