The MULE is a man-portable tripod-mounted or shoulder-fired unit which incorporates a laser range-finder/target designator which works with all laser-guided weapons now under development. It is used to locate targets and to guide laser-guided projectiles to their targets. It can track moving targets and combine range, azimuth, and elevation into a digital message to be sent to the tactical fire control center. The major components are the Laser Designator/Rangefinder Module and the Stabilized Tracking Tripod Module. A supporting item of equipment is the North Finding Module.

The system is capable of operating on 24 volt DC rechargeable batteries, or from 24 volt DC vehicle power using an external power adapter. It can effectively range a moving target to 3,000 meters, and a stationary target to 5,000 meters.
