The term HK-Tank refers to a wide variety of Skynet's ground-based combat Hunter-Killer vehicle. Developed from the original T-1, the HK-Tank is several stories tall and vaguely humanoid in overall shape, possessing a rotating, conning tower-like "head", two steel "arms" equipped with twin-barreled directional plasma cannons, and two "legs" consisting of massive individual tank treads. While formidably armed, the HK-Tank can be easily destroyed by a well-placed demolition charge.
