The Type 94 Gas Scattering Vehicle was a variant of the Type 94 Tokushu Keninsha adapted to chemical warfare. The purpose of the trailer was to disinfect the area contaminated by the Type 94 Gas Scattering Vehicle. The armament of the TK was removed and the tank was sealed to protect against the chemical agents. The trailer contained a decontamination agent. A release vent was located on the lower rear. When in use, the trailer would release a bleaching agent to counteract the chemical/biological agents.
