Nothing is known about the Active Sledge's design, but it apparently has a total length of 90m with its ice-breaking equipment fully deployed.
Not much is known about the Active Sledge's technology, though it can be assumed to possess the systems common to every Object. It is apparently an amphibious second-generation Object, designed for invasions in maritime areas with thick ice. Aside from its main cannon, it has a various powerful ice-breaking equipment, such as blades, rotating chains and a spike, among others.
Operating together with the 29th Mobile Maintenance Battalion, the Active Sledge's Elite is the older sister of the Snow Quake's Elite. The two are famous for their rivalry and quarrels, with the Active Sledge's Elite acting playful towards her rebellious younger sister.
The Active Sledge was one of the three Objects deployed to fight against the 24th Mobile Maintenance Battalion and its Object, the Indigo Plasma. Its mission was to cut off the retreat of the enemy Object from the sea, while the 37th's Baby Magnum and the Snow Quake attacked it directly from land.
The Active Sledge tried to join the fight after the Indigo Plasma damaged the Snow Quake's propulsion device, but it was suddenly greatly damaged and sunk by the Indigo Plasma's dummy models, which had been hiding underwater.
