Designed alongside CP-24, the Active Shield Unit was the second idea for improving little baby Zoids. Give them better defence, and while you’re at it, offense too seemed to be the general idea of this modification. Mounted onto the hips of the Snipe Master, Helcat and Spinosapper, and the shoulders of the Hammerrock are two large multi-panel shield generators. They can fold in half, revealing a tough armour plate on the back of the generators, about equal to the Spinosapper’s armour. However, to create the shield, the panels must open, and this is when they can be attacked.
The generators create a unique dome-shaped shield that is designed to allow the equipped Zoid full freedom of movement, while providing pseudo-omnidirectional protection. This flattened dome covers the articulated shields with less than half a meter of overlay. Because of how large the panels are, the shield all the way around is as strong as a Shield Liger’s, but be warned, because it also draws just as much power, and on Zoids like these, that will tire them out pretty quickly. Use the shield carefully and judiciously and it will be your eternal friend. Use it willy-nilly and it will punish you for being so careless. It is worth noting that the shields are on arms capable of pointing them in just about any direction on the zoid's flank, are rather sturdily-constructed, and vaguely resemble the Breaker's articulated shields.
Yeah. Not subtle at all.
The CP-25 also provides a set of weapons that can beef up any Zoid they’re equipped to. The first weapon is a tri-barrelled impact cannon. This cannon has a smaller calibre than the standard ones, measuring in at AZ88mm. The three barrels are also splayed slightly apart, increasing the chance of one shell hitting, but severely reducing the chance of them all hitting the target. The maximum effective range of this weapon is 150 meters, and it mounts on the tail of the Snipe Master, facing backwards, on the left wrist of the Hammerrock, and replacing the 115mm Machine Gun of the Spinosapper, facing backwards. On the Helcat it is absent.
The next set of weapons are two ARZ 45mm cannons. These are standard cannons with the usual projectiles, and they fire at a rate of three shots per second each. They are fixed forward on the wrists of the Snipe Master, the shoulders of the Spinosapper and the front shoulders of the Helcat, adding much needed dependable firepower. On the Hammerrock, these cannons are missing. The final pair of weapons are two TEZ 25mm Cannons that operate in basically the same way as the ARZ cannons, but with a slightly reduced range and a faster firing rate of five shots per second. These mount on the back of the Snipe Master, to either side of the scope package, on the back of the Hammerrock, replacing the missiles and pointing backwards for rear defence and on either side of the back-mounted guns on the Helcat.
