"Drive away the train with fuel for our tanks"
does this order mean to assault and reroute a train charged with fuel in order to use the fuel for the tanks?
It is impossible to determine because too many of the phrases and words have multiple meanings. "Drive away" could mean to take control of the train and go somewhere, or it could mean repel the train, prevent it from getting closer. "Tanks" could mean fuel containers or armored vehicles.
