If there is a big God that can edit the script, refer to the Dismounts Script file (https://forums.eagle.ru/showthread.php?t=109676&highlight=mbot), you should be able to do it.
This script file can only play with the map that he gives. If we edit the map to add new vehicles, the added vehicles will have no effect.
Can you edit the script file again, so that the new vehicle will be effective.
