In Brief: The Attack Unit consists of two 80mm semiautomatic cannons that can be mounted to a number of Helic Zoids (and the Zaber Fang), giving them needed additional firepower.

Weapon Type: Twin Shelled AZ Cannons
Ammunition: 80mm solid shells
Rate of Fire: Semiautomatic

Description: The three Empires: the Zenebas Empire, the Guylos Empire, and the Neo-Zenebas Empire had a way with extremely heavily armored, mass produced field command Zoids. Long before the Blade Liger was ever dreamt of, Red Horns and Iron Kongs were rolling onto the field of battle. This was always a problem for the Helic military, but they reasoned that there was little they could do about it but send their own larger Zoids, such as the Gordos, to duke it out with the heaviest of enemies. When that failed, the handy Helic talent of air superiority came in useful. While this was never really enough to give the Helic Republic an upper hand, it did stop their troops from being slaughtered on the field of battle for a while.

The Hybrid Vulcan Cannon changed everything. Zaber Fangs mounting the weapons were the least of the concern of the Republicans: Iron Kongs, Red Horns, and the new Guylos weapon, the Dark Horn, were entering the field armed with the Hybrid Vulcan Cannon. When one of these massive Zoids lumbered through, the Helic regulars, mostly equipped with Command Wolves or other lighter Zoids, could no longer hope to have any staying power in a fight. Dodging and relying on armor were concepts of the past. There was no time to call in an airstrike or a mortar barrage or a larger Zoid. Even missiles became less effective as 60mm shells knocked them from the air. You had to beat the enemy then and there - or you would die trying.

So, the Helic response to the Hybrid Vulcan Cannon was a pair of AZ 80mm cannons - semiautomatic and mounted to the meanest and humblest of the Helic Zoids...and a few lesser-armed higher-performance designs too. Hardly Zoid-destroying weapons, but hardly insignificant, and able to be used on the move, letting Zoids run and gun against more heavily armed foes. The Zaber Fang gaining the ability to carry the Attack Unit was a product of reverse-engineering, and later carried over to the competitive battling circuit.

On the Cannon Tortoise, the Attack Unit cannons point wherever the mortar cannon is pointing. On the Command Wolf, Whitz Wolf, and Zaber Fang, the Attack Unit can pivot 90 degrees either direction horizontally (like a turret), and up to 20 degrees up or down. On the Houndsoldier, concerns about higher-speed stability led to the Attack Unit mounting as a fixed weapon, pointing wherever the Zoid does—however, unlike the Buster Cannons it replaces, the Hound need not worry about recoil. On the Godkaiser it mounts one barrel on either shoulder and they can turn independently, with a 45 degree horizontal and 10 degree verticle incline, though they are facing forwards.

And now, thanks to the transfer of many old Helic designs into the public domain following their merger with the ZBC, this part is available to the common pilot.
