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.
With the increase of effective anti-HK tactics used by the Resistance to not only disable these units but to scavenge them for heavy weapons, power sources and armor, Skynet has started equipping some units with crew compartments, containing concealed endoskeletons to counterattack the human assault teams.
Kyle Reese and another Resistance soldier were trying to toss canister bombs to destroy an HK-Tank. Kyle tossed the charge successfully, but the other did not, and was killed by the HK-Tank. The HK-Tank was destroyed after a while when running over the charge tossed by Kyle.
Terminator 2: Judgment DayEdit
Terminator: The Sarah Connor ChroniclesEdit
Terminator: Resistance Edit
Several HK-Tanks are deployed by Skynet with at least two fought as bosses. One in the ruins of Los Angeles and another in the final battle against Skynet. The first HK-Tank is destroyed without support by stunning it with rocket launcher while also shooting it from behind at an exposed panel. This, along with several certain security codes obtained from them, enables the Resistance to reprogram and utilise one HK-Tank for themselves.
- Both the HK-Tank from the first two films have a few differences from each other, for instance, the HK-Tank from The Terminator has only a one plasma cannon on each arm, while in Terminator 2: Judgment Day, the tank seems to be equipped with two plasma cannons now, might be a bit inconsistant to the design but it might have been a small change to make the two films feel different in the future war.
- A different type of HK-Tank appears in the video game Terminator 3: War of the Machines. This variant lacked a "head" like the original model and instead had a cluster of large sensors on its front. It's arms extended out further than the original model and mounted triple plasma cannons. It is also much smaller.
- There is a concept art of the HK-Tank for the film Terminator Salvation. This version of the HK-Tank resembles an oversized version of the T-1 in Terminator Salvation. Note that this HK-Tank is mounted with miniguns just as well as the T-1.
- In Terminator Salvation, the defense turret at the perimeter of Skynet Central appears to be a modified HK Tank with its treads removed, while the torso mounted onto the wall. This allows it to rotate and effectively destroy incoming targets, but leaves it as stationary defense.
- The HK-Tank in Terminator Salvation game is an earlier model of the tank. It is armed with dual plasma cannons and dual machine guns. Unlike its successors, this HK-Tank did not have a visible head.
