The v-188 Penetrator is both a mobile and immobile weapon. To achieve (some) mobility, the weapon is mated atop of a 440 Super-Heavy Armoured Chassis. These treaded vehicles while heavily armoured, offer limited protection against enemy fire. Power for the weapon is provided either by an onboard energy cell or by a towed energy capacitor trailer (power trailer). What may or may not be a surprise, the Rebel Alliance has acquired a small number of v-188s either through theft or via the black market.

    According to unsubstantiated rumours, the Rebels have mounted their v-188s on modern repulsorlift vehicles. In reality, they employ the same conveyance as the Empire, except with a few modifications. It must be noted however, that the small number of v-188s deployed to "regular field units" in conventional theaters and SpecForces receive the conveyance. Those v-188s kept at Rebel warehouses generally remain dismounted. Unlike Imperial 440s, the Rebels have added repulsor motivators to increase mobility. Additionally, the Rebels have equipped their mobile v-188s with a separate fusion generator allowing for unlimited fire. Meanwhile fire rate and fire control improvements were had due to high-efficiency rechargers, and targeting computer upgrades.
