This is the area where ATP Officers can train with their Air Treks.

This area is filled with an obstacle course full of rails, walls, ledges, and high drops.
It was made to try and resemble different urban environments, so as to be used to such courses.

There is also a section of the area to practice with shooting ATP guns against moving targets while on AT's.
These targets are merely moving mannequins that keep cycling along a fixed underground conveyor. These targets are constantly switched out when damaged too hard and using physical force against them is not allowed.
