Ghost in the Shell: Stand Alone Complex S01E02 - Testation

A prototype intelligent tank built by Kenbishi Heavy Industries suddenly activates. The military, which was not entirely decided about approving the purchase, is unwilling to intervene in the incident and Section 9 is called in for assistance. Section 9 sends Tachikomas to hunt down the vehicle and he plans to fire on it where there are no residential buildings. But despite his efforts, the tank keeps rolling. It looks as though it's headed towards a specific destination. Where is it going? And for what reason?
