AATIS

The Anti-Aerospace Tactical Intercept System, commonly referred to as AATIS or the Iron Shield, is a networked system of stationary turreted mass-driver cannons that serves as a defense against hostile spacecraft on some UEG colonies, either in lieu of, or in conjunction with orbital weapon platforms.
== History ==
AATIS networks were constructed on numerous SATO colonies and member worlds, including Harvest, Mirial and Vekta. During the Fleet Week Ambush on September 15, 2541, the UIR coopted the AATIS network in Kaname city and turned it against the UNSC ships participating in the Fleet Week parade, successfully shooting down several frigates and destroyers before UNSC forces regained control.
