Mechanical

Mechanical units are composed of a biological and mechanical component. Most mechanical units are vehicles with a Terran driver. The Protoss Dragoon is another example which may be cybernetic in nature.

Due to their biological components, mechanical units are vulnerable to some special abilities, such as a Queen's Broodling attacks. However, they are immune to some special abilities which can affect organic units, such as the Science Vessel's Irradiation ability.

Due to their mechanical component, they are vulnerable to abilities like a Ghost's Lockdown ability.
