The Police Tank is a vehicle that appeared in the episode "Bart Stops to Smell the Roosevelts" when the police was surrounding the school. It had a much important role in "Much Apu About Something", where it was used during the parade for the statue. Bart pulled a lever on the fire truck, which sprayed water on the officers.
Chief Wiggum attempted to use the tank against the fire truck, but the tank rolled over foam, which caused it to lose control. The tank rolled out of control before crashing into the Kwik-E-Mart and causing the store to collapse.
- This vehicle is not a tank, it's technically an APC.
