Ghost

"You call down the thunder and I'll reap the whirlwind."

- Terran Ghost

Ghosts are Terran covert operatives known for their psychic abilities.

Overview
Ghosts were chosen from psychically-gifted individuals who successfully completed the Ghost Program's rigorous training and augmentations. These individuals then served as commandos and assassins. Standard Confederate practice was to implant Psychic Dampeners into all Ghosts as a safeguard against insubordination. , however these implants could be disabled.

Ghosts channelled their psionic energies through their Hostile Environment Suit, a specialized skinsuit laced with psi-sensitive artificial muscle fiber, to augment their physical capabilities. A cloaking device and requisite power supply were frequently issued as well.

At the fall of the Confederacy, the standard Ghost armament was the C-10 Canister Rifle, firing 25mm HE rounds in addition to more specialized ordnance such as lockdown missiles.

Ghosts were frequently tasked to locate targets for and provide targeting for tactical nuclear strikes. Their reconnaissance role was aided by cybernetic enhancements to their eyes.

Spectres

 * See: Spectres

After the Brood War some Ghosts were exposed to terrazine gas, a substance known to drive genetic mutation in psychics. This was part of General Horace Warfield's Project Shadow Blade, which also used covertly-acquired Protoss technology as part of its research. The result were "enhanced" Ghosts known as Spectres.

StarCraft
Ghosts are support units, best trained for their special abilities. Against Terran and Protoss opponents a small number of Ghosts can cripple an army with Lockdown. On the offensive, the judicious use of Cloaking can get a Ghost close enough to launch a devestating nuclear strike. Detectors are critical to guard against infiltrating Ghosts since it is difficult to spot the tell tale 'shimmering' that cloaked units exhibit for such a small unit, especially when the Ghost is not moving.
