The Polar Battle Bear is a 1.4 ton snow vehicle deployed by the Joe team for use in Arctic climates and/or heavily snowed-in areas. The Battle Bear is built from high grade steel for durability in the field, giving it an effective material strength of 10. It's not the most roomy vehicle or even very well insulated from the environment, but it definitely gets the job done. The Battle Bear has these capabilities:

Bullet-Proof Windshield: the front of the Polar Battle Bear (and thus its driver) benefits from the presence of an acrylic composite, bullet-proof windshield. While this windshield doesn't provide the entire vehicle additional protection against attack, it does offer +2 defense versus attacks from the front to both the Polar Battle Bear and its Joe driver.

Heat-Seeking Missiles: mounted on the two steering skis, these surface to surface miniature missiles are quite effective in striking their targets in the icy northern (or southern) wastes. Each of these missiles can strike a target to inflict intensity 10 damage, though if the Polar Battle Bear's driver strikes a single opponent with both rockets at once, they inflict +1 damage.

Lightning Speed: sort of a misnomer, this function details the mobility of the Polar Battle Bear. Propelled by two powerful treads driven by a 160 H.P., rear-mounted v6 engine, with steering controlled by two front-mounted skis, the Battle Bear can achieve speeds of approximately 42 miles per hour, though this may vary slightly depending on the number of passengers and terrain involved.

Quartz Halogen Headlamp: the front of the Polar Battle Bear is equipped with a powerful quartz halogen lamp, allowing its driver to see the terrain before him even in the darkest of nights. The lamp illuminates the area in front of the Battle Bear with intensity 8 light, and if used cunningly, it can be utilized to inflict a blinding attack upon an opponent...

Passengers: strictly speaking, the Polar Battle Bear is a one man vehicle - it can be considered an oversized, heavily armed snowmobile when you get down to it. However, the back of the Battle Bear has been fitted with a 'rear battle deck', which allows up to two riders to latch on to the Battle Bear wherever its driver takes it. It's not a comfy ride, but it's faster than walking...

Roll Bar: this special steel bar, wrapped over the driver's seat of the Polar Battle Bear, offers protection to its driver regarding rolls and crashes. It wouldn't shield him from, say, a bomb blast, but if the Battle Bear gets struck or toppled somehow, at least its driver will benefit from +2 protection against the resultant damage applied to the vehicle.

Synchronized 50mm Cannons: fitted with a 650 round drum of ammunition, these twinned 50mm cannons can inflict devastating damage upon enemy personnel, vehicles, and fortifications. They fire to inflict damage as would a +7 weapon per deadly burst, and can dish out punishment for quite a while considering the exceptionally large amount of ammunition available to them.

Once he had rejoined the G.I. Joe team, admittedly a little bit after his fellow Arctic troops did, Frostbite started tooling around in an updated version of the Polar Battle Bear. This 'new' vehicle, which he named the Rock Slide, is much more heavily armed than its predecessor, when you get down to it, as it has added a rather large rocket launcher situated immediately behind the driver's seat, which has these capabilities:

Rotary Multi-Missile Launcher: the chief difference between the Polar Battle Bear and the Rock Slide is, of course, this exceptionally large rocket launcher. This thing is loaded with four powerful rockets, each of which track a target by his heat source (easy to find in the Arctic), and inflict intensity 10 damage to whatever they hit - and anyting else within striking (near missile) distance.
