Piranha 4

The Piranha 4 is a 20-ton striker that fights close in, cruising at 97 km/h and topping out near 151 km/h on its 180 XL fusion engine, a 3072 field refit of the 3051 original. Where that original packs six Machine Guns into the left torso and six into the right, this configuration mounts four Machine Guns and a Machine Gun Array in the left torso, and four Light Machine Guns with a Light Machine Gun Array in the right torso. The center torso's ER Small Laser is replaced by a targeting computer, while the twin ER Medium Lasers in the arms carry over unchanged. It is a field refit built at various sites rather than a factory-line product.
