Technology & Combat Characteristics
By AD 2307, the mainstay mobile suit of the Human Reform League (HRL), the Tieren Ground Type, has been in use for over a decade and a variety of variants have been developed. The Tieren Antiaircraft Cannon Type is one such variant and it specializes in anti-air combat. With the mainstay mobile suits of the two other blocs (the Union and the Advanced European Union) being flight type units, it is only natural for the HRL to create an anti-air mobile suit.
The Tieren Antiaircraft Cannon Type is mainly used for defending the HRL's bases and its orbital elevator. It is armed with various anti-air weaponry, including the Quadruple 155mm x 50 Caliber Rapid Fire Anti-Air Cannons on its head, four 4-tube Anti-Air Missile Launcher, and a 60mm 6-barrel Liquid-Cooled Vulcan Gun. It also has a Composite Search System for detecting airborne enemy units. Soldiers on the field prefer to call the mobile suit by its nickname "Ciwei" (which means "Hedgehog" in Mandarin Chinese).
History
In AD 2306, the HRL conducted a massive military exercise in preparation for the next year's 10th anniversary of its Orbital Elevator's electricity transmission. As the exercise near its end, a siren suddenly sounded. In the air, four mobile suits resembling the AEU-05 Hellions were spotted. Like the other audiences in the VIP stand, a young Robert Spacey panicked and ran. As he ran to the center of the VIP stand, he met Deborah Galiena, a representative of the United Nations, who told him in a cool and collected manner not to worry as the 'Ciwei' would be deployed soon. As if hearing her words, the Tieren Antiaircraft Cannon Types appeared out of a hanger and their anti-air cannons immediately fired in rapid succession, destroying the enemy units in an instant. An announcement was then made to calm the audience down, and at the same time, Robert heard Deborah muttering to herself that all this was just a show by the HRL.
Sometime after the defeat of Celestial Being in AD 2308, the HRL's Orbital Elevator came under a terrorist attack. A bomb in a luggage bag went off and soon after, three AEU Hellion-type mobile suits operated by terrorists approached the Orbital Elevator for a suicide attack. The HRL quickly deployed the Tieren Antiaircraft Cannon Types, which shot down two of three enemy units, with the last unit destroyed by the GNY-002F Gundam Sadalsuud Type F (piloted by Hixar Fermi) that was hiding in the waters nearby.
