Evidence & current status
Army original-programme capabilities and the current XM marketing offer are kept separate. Additional autonomy and mission roles described as future capabilities are not treated as fielded.
MUTT is General Dynamics Land Systems' ground-robot platform underlying the US Army's Small Multipurpose Equipment Transport programme. Its primary purpose is to carry soldiers' equipment and provide mobile electrical power. The Army's early programme description included a substantial production order, while GDLS now describes S-MET as delivered and fielded.
The control concept includes a handheld remote, teleoperation and a following tether. These practical forms of assistance should not be collapsed into a claim that all vehicles conduct fully autonomous resupply. GDLS describes more advanced mission roles as future or configurable capabilities, rather than established equipment on every Army transport robot.
The manufacturer now markets MUTT XM, a newer eight-wheel hybrid-electric platform with expanded mobility and payload ambitions. XM is recorded as a related offering, not evidence that the Army's original S-MET fleet has been replaced or that its specifications have changed. The figures below identify the Army's original public S-MET capability description. In particular, the distance-and-time requirement is a duty-cycle statement, not proof of uninterrupted driving for three days at maximum load and speed.
