U.S. MW-81 Bulldog prototype.

The MW-81 Bulldog is an Ambulatory Surveillance Vehicle (ASV) designed for all-terrain, all-weather and night capabilities. Its role is to provide a mobile quick deployment and deep insertion capable, multi-sensor, battlespace awareness asset for small unit tactical reconnaissance teams, fire support coordinators, and special reconnaissance forces.

It features advanced mobility (all terrain, highly agile, hybrid electric drive, exceeds JATRAN capabilities), survivability (suppression of all signatures, camouflage/concealment treatment), sensor suite (on-board, extended range, multi-spectral imaging and sensing, target acquisition, target designation), and command and control (long range, secure, positioning/navigating, cooperative engagement tactics) capabilities.The Bulldog was designed for long range Reconnaissance, Surveillance and Targeting Acquisition (RSTA) missions in cooperation with Small Unit Operations. In addition, it provides strategic mobility to reach and engage the threat, tactical mobility for effective use of fire power, fire power to defeat soft and armored targets, and battlefield survivability to carry out combat missions.

When operating using only stored electric power, the MW-81 is capable of silent movement and silent watch.
