The UIR Anti-Air Turret were weapon batteries used by the Union of Independent Republics as a defense system against invading COG aircrafts. These four-barrelled emplacements fired large flak rounds at sufficient quantities.
Although they are unable to target high-altitude aircrafts like anti-air missiles - due to the limitation of flak rounds - they still pose a threat to low-altitude aircrafts such as King Ravens and diving Petrels.
Battle of Aspho Fields
During the Battle of Aspho Fields, dozens of these turrets were seen attempting to shoot down oncoming COG aircrafts. Although they weren't physically seen, their flak rounds were. Whilst the weapons manage to shoot down a large number of King Ravens, a few carrying Dominic Santiago and Victor Hoffman's squad managed to safely land and stole the Hammer of Dawn plans, thereby ending the Pendulum Wars.
Assassination of Ukkon
One year after the Hammer of Dawn Strikes, Gabriel Diaz went to Vasgar to find intelligence and materials needed to take down Ukkon. In major UIR military facilities such as the UIR Chemical Weapons Depot, several of these Anti-Air Turrets were present, albeit broken and disabled.
