Denise Crosby and Judson Scott previously appeared together in Symbiosis (1988). In both productions, Crosby plays an incorruptible law enforcement officer with a troubled past, while Scott plays the villain-of-the-week.
Although the tank in this episode is not an amoured stagecoach, by referring to it as a "battle wagon" the writers really must be making a reference to The War Wagon (1967).
