サージェント・スローター
The vehicle first appears in "G.I.Joe" #51. A Dreadnok-led escape by Zartan from Joe Headquarters leads to a multi-vehicle chase through the swamps. The Thunder Machine's weapons severely damages Heavy Metal's MAULER tank and easily knocks aside Crankcase's A.W.E. Striker. It comes down to Cross Country and Sgt. Slaughter on the HAVOC vehicle chasing the Thunder Machine. Thrasher's driving skills, weaponry and willingness to take suicidal risks allow the Dreadnoks to temporarily escape the HAVOC. Sgt. Slaughter actually finds them later but the team's disguise skills are sufficient to fool him.
