This paper model is a SnowRam with optional Luggage, based on the sci-fi TV series Battlestar Galactica, the papercraft was created by Revell-Fan. There are 1:18, 1:24 and 1:32 three scale versions. A Snowram is a landram that has been altered for use in arctic environments. Starbuck uses the top-mounted turret to shoot down a Cylon Raider on Arcta. That snowram is later accidentally disabled by Haals' laser pistol.
A Landram is a tracked vehicle used for ground operations, typically shuttled to a planet via a shuttle. It is capable of holding crew and cargo, and is equipped with a top mounted turret weapon. A landram was used for the initial scouting of Carillon. They were later used to evacuate civilians and warriors from the "pleasure resort" on the planet.
A landram is deployed to the surface of Kobol. A version of the landram modified for use in frigid climates is the snowram.
Another modified version, this time without the cabin and open to the air, and presumably without Colonial markings, appears in "The Magnificent Warriors". It is stolen by agents of the Sheriff in Serenity. [Source: Battlestar Wiki]
