The Jackal is a terran unit in StarCraft II.

Overview
The Jackal is a fast vehicle similar to the Vulture, equipped with four wheels like a buggy and armed with a flamethrower.

Game Unit
The Jackal's weapon targets only ground units. It does splash damage in a line, targeting one unit but striking all units along the line. The attack is well-suited to destroying weaker units such as marines. However, it does 10 damage, making it quite ineffective against single units. A recommended tactic is to use the Jackal as an ambush unit, positioning it on high ground to attack units below it.

The Jackal must stop in order to attack. The weapon strikes targets instantly. However, units that move out of the flame take less damage. The attack does not damage allied units.

The Jackal is produced from the factory with no other requirement, meaning an attached nuclear reactor can double the rate of production.

The Jackal has 75 hit points, down from 125 hit points, with a slight increase to movement speed. This renders the Jackal both fast and fragile. The Jackal is fast enough to chase down enemy units and easily reposition itself.

Upgrades
The Jackal has an upgrade which doubles its attack range.
