Dear staff at Offworld Industries,
Please remove the ZSL-92 and change the ZSD-89 to the machine-gun variant.
First, the ZSL-92 is outdated equipment. The Chinese PLA is currently phasing it out and has been selling it to African and Southeast Asian countries.
Second, although a cannon-armed variant of the ZSD-89 does exist, it was introduced around 1990 and produced in very small numbers. It was never officially fielded by the Chinese military. All ZSD-89 vehicles currently in service with the Chinese armed forces are machine-gun variants.
