Special Abilities

Tracked (Ex): The T-1 GAAV travels on heavy tracks, allowing it to ignore difficult terrain entirely.

Trample (Ex): As a full-round action, the unit can move up to twice its speed and literally run over any opponents at least one size category smaller than itself. The T-1 GAAV merely has to move over the opponents in its path. The creature does not need to make an attack roll; each creature whose space it moves through takes damage. A target of a trample can make a REF save (DC 12) for half damage. If it attempts the save, it can’t make an attack of opportunity against the trampling T-1 GAAV due to the creature’s movement. The T-1 GAAV can deal trample damage to a given target only once per round.


The original prototype for the various Hunter Killer tanks, this was originally created and sold to the US military to be used as a semi-autonomous unit. It was designed to be sent in ahead of infantry units into hostile territory, as it could also enter most regular buildings.

After Skynet began its war to exterminate humanity, it used the base model of the T-1 to easily create more of the unit, incorporating a fully autonomous primitive AI, which allowed it to be deployed with simple instructions, which it would do its best to accomplish – or until the unit is destroyed.

Physically the unit is approximately six feet in height, and nearly eight feet in length. It weighs over 500 pounds. It moves about on treads, giving it excellent mobility over rough terrain, and it is armed with a pair of multi-barreled Gatling guns. The unit carries 5000 rounds of ammunition, which is stored inside its torso in special canisters, which are hardened against damage, in order to prevent a cook-off which would otherwise destroy the unit.

As stated, the unit has a primitive AI, giving it the ability to make battlefield decisions without having to contact Skynet. As long as it has a basic mission parameter, it will work diligently and to the best of its ability.

Thanks to how easy it is for Skynet to construct these units, they are still built and sent into the battlefield. The same resources needed to create a single tank, or even a handful of Terminators can construct multiple T-1 GAAVs.
